Sap Data Cleansing Process Steps

Data Cleaning In Six Steps

SAP Data Quality Management, microservices for location data: Basic Address Cleansing

The first step before starting a data cleaning project is to first look at the big picture. Ask yourself: What are your goals and expectations?

To achieve those goals youve set, next, you must plan a data cleanup strategy. A great guideline is to focus on your top metrics. Some questions to ask:

  • What is your highest metric looking to achieve?
  • What is your companys overall goal and what is each member looking to achieve from it?

A good way to start is to get the key stakeholders together and brainstorm.

Here are some best practices when it comes to create a data cleaning process:

Introduce Temporary Process Fixes

The existing supplier management process creates data issues that are targeted by the prepared data cleansing activities. Digital transformation will possibly bring tighter data governance, preventing the appearance of data issues, but it will only come into effect with go-live. However, on approaching the deadline with almost 100 per cent vendor data quality requires a temperate patch to the legacy processes for stopping the leaking tap.

Introducing in such temperate fixes requires an analysis of the existing process in order to understand precisely how incorrect data enters the system or is being corrupted or duplicated during some BAU process. It is not uncommon for the supplier evaluation and onboarding process to emerge and evolve with the organisation therefore, processes are not always adequately formalised for the analysis. Datanovel can help to discover, map, and analyse the existing process, evaluate steps that should be temporarily fixed, and provide tools for minimising the impact to cycle time.

Process fix implementation for a legacy process is a change management challenge which should be avoided when data can be fixed at the ETL process level during data migration. Usually, a process fix is the only solution when the data becomes irreversibly changed, removed or added without a compliant review or verification.

What Is Data Cleansing

Data cleansing is the process of resolving issues with duplicate data and making sure that such issues don’t occur in the first place. This includes double-checking the system’s data quality and addressing all problems: starting with data extraction from SAP and satellite systems, followed by automatic and manual checks in Microsoft Excel or other data visualization programs, and completed with system update during a business interruption.

Guide To Data Cleaning: Definition Benefits Components And How To Clean Your Data

When using data, most people agree that your insights and analysis are only as good as the data you are using. Essentially, garbage data in is garbage analysis out. Data cleaning, also referred to as data cleansing and data scrubbing, is one of the most important steps for your organization if you want to create a culture around quality data decision-making.

Why Is Clean Data Important

Business operations and decision-making are increasingly data-driven, as organizations look to use data analytics to help improve business performance and gain competitive advantages over rivals. As a result, clean data is a must for BI and data science teams, business executives, marketing managers, sales reps and operational workers. That’s particularly true in retail, financial services and other data-intensive industries, but it applies to organizations across the board, both large and small.

If data isn’t properly cleansed, customer records and other business data may not be accurate and analytics applications may provide faulty information. That can lead to flawed business decisions, misguided strategies, missed opportunities and operational problems, which ultimately may increase costs and reduce revenue and profits. IBM estimated that data quality issues cost organizations in the U.S. a total of $3.1 trillion in 2016, a figure that’s still widely cited.

Have Confidence In Your Data

Youve done it! Your master data has been successfully migrated to SAP S/4HANA, and you can now make a fresh start with a clean database without legacy data.

A well-planned changeover with cleansed data has several positive developments. These include, for example:

  • Improved performance of SAP S/4HANA
  • Optimized business processes
  • Less disk space required after cleanup
  • Easy administration of the database
  • Lower running costs for space in the main memory
  • Fewer resources for the changeover and reduced overall operating costs

Your hard work and advance planning has therefore paid off. To prevent its benefits from fizzling out, however, it is advisable to ensure that the data quality remains consistently high. Even if it seems arduous: take time to complete a regular quality check. Have duplicates crept in again? Are any data records incomplete or incorrect? This not only affects the material master data. Remember that all master data can change regularly, due to relocations or changes in company name, for instance.

The time that you spend on quality control and maintenance of your material master data is therefore well invested if you want to work with it to optimum effect.

Data Profiling Vs Data Cleansing Whats The Key Difference

SAP HANA Academy – Smart Data Quality/Integration: Procedure Transformations [SPS09]

In a data quality system, data profiling is a powerful way to analyze millions of rows of data to identify errors, missing information, and any anomalies that may affect the quality of information. By profiling data, you get to see all the underlying problems with your data that you would otherwise not be able to see.

Data cleansing is the second step after profiling. Once you identify the flaws within your data, you can take the steps necessary to clean the flaws. For instance, in the profiling phase, you discover that more than 100 of your records have phone numbers that are missing country codes. You can then write a rule within your DQM platform to insert country codes in all phone numbers missing them.

The key difference between the two processes is simple one check for errors and the other lets you clean up errors.

Data profiling and data cleansing arent new concepts. However, they have largely been limited to manual processes within data management systems. For instance, data profiling has always been done by IT and data experts using a combination of formulas and codes to identify basic-level errors. The mere profiling process would take weeks to accomplish and even then, critical errors would be missed. Data cleansing was another nightmare. It could take months to clean up a database, including removing duplicates . While these methods may have worked for simple data structures, its next to impossible to apply the same methods on modern data formats.

Get Rid Of Unwanted Observations

The first stage in any data cleaning process is to remove the observations you dont want. This includes irrelevant observations, i.e. those that dont fit the problem youre looking to solve. For instance, if we were running an analysis on vegetarian eating habits, we could remove any meat-related observations from our data set. This step of the process also involves removing duplicate data. Duplicate data commonly occurs when you combine multiple datasets, scrape data online, or receive it from third-party sources.

Remove Duplicate Or Irrelevant Observations

Remove unwanted observations from your dataset, including duplicate observations or irrelevant observations. Duplicate observations will happen most often during data collection. When you combine data sets from multiple places, scrape data, or receive data from clients or multiple departments, there are opportunities to create duplicate data. De-duplication is one of the largest areas to be considered in this process. Irrelevant observations are when you notice observations that do not fit into the specific problem you are trying to analyze. For example, if you want to analyze data regarding millennial customers, but your dataset includes older generations, you might remove those irrelevant observations. This can make analysis more efficient and minimize distraction from your primary targetas well as creating a more manageable and more performant dataset.

As weve covered, data analysis requires effectively cleaned data to produce accurate and trustworthy insights. But clean data has a range of other benefits, too:

Key to data cleaning is the concept of data quality. Data quality measures the objective and subjective suitability of any dataset for its intended purpose. There are a number of characteristics that affect the quality of data including accuracy, completeness, consistency, timeliness, validity, and uniqueness. You can .

Reevaluate Your Processes And Techniques

Expect to periodically reevaluate your data cleansing processes that you run in 2021. As you acquire other businesses, add new data systems, and redesign your services, your data needs will change.

You will want to repeat steps one through four to get your existing data cleaned to fit your new goals while ensuring the best data cleansing processes remain unchanged. At this time, update your strategy and get your data governance involved.

Is There A Real Problem With My Data

Simple validation of the supplier master data is an excellent starting point for checking the data quality.

In order to undertake such assessment, Datanovel offers a ‘magic button’ a self-serve Excel tool that takes your vendor file and validates the data, counting a percentage of lines ready for migration. This means that this data will fit into the new system because of its correct format and structure. .

However, validation will not indicate every issue . Therefore, whenever the tool shows an overall readiness rate below 95 per cent, it is recommended that a complete health assessment of the vendor file is conducted by verifying all essential information with official databases. Datanovel is here to help you with such a health check, and you pay no fee until you request another report .

Data Hygiene How Often To Do It

The data hygiene of our clients ‘and potential clients’ business databases is not a topic that we can leave alone. No good manager should assume in advance that employees of various departments have never made and will not make mistakes when entering new data or that everyone will adhere to uniform recording standards. Error is a human thing, so it simply has to be time for data cleansing in the enterprise. Either it should be performed by a properly trained employee , or we should outsource this task to an external company specializing in this subject, preferably one that has an ISO / IEC 27001 information security certificate.

How often should data hygiene be carried out in the company? Well, it depends on the size of the base. Medium and large enterprises with a large number of records should repeat data cleaning every 3-6 months. For smaller companies, it is enough to do data hygiene about once a year.

Type Conversion And Syntax Errors

SAP HANA Academy – Smart Data Quality: Data Cleanse Transformation Basics [SPS09]

Once youve tackled other inconsistencies, the content of your spreadsheet or dataset might look good to go. However, you need to check that everything is in order behind the scenes, too. Type conversion refers to the categories of data that you have in your dataset. A simple example is that numbers are numerical data, whereas currency uses a currency value. You should ensure that numbers are appropriately stored as numerical data, text as text input, dates as objects, and so on. In case you missed any part of step two, you should also remove syntax errors/white space .

Data Cleansing Step : Filling Missing Data Vs Erasing Incomplete Data

The next step in database hygiene is preventing the possession of incomplete data. Anyone who works with data at least a little knows well that the information, in addition to being reliable and up-to-date, should also be complete.Incomplete data contaminates the database, lowering its business quality.As an example, let’s take the database of B2B contractors addresses, which are saved in CRM in the following format: voivodship, commune, postal code, city and street.

Let’s assume that in our system we want to have only complete company addresses, i.e. complete data sets . We can approach this topic in two ways:

  • delete all records that have an empty value in any field ,
  • complete incomplete records , and only what cannot be retrieved with a supplement remove.
  • Of course, we decide to clean the database the second way.In order to facilitate this task and perform it fully professionally, it is necessary to define some repetitive and exhaustive rules that will apply to this data set in turn. They take the following form:

    After applying the above set of rules, our cleaned database of company addresses looks like this:

    What Kind Of Data Errors Does Data Scrubbing Fix

    Data cleansing addresses a range of errors and issues in data sets, including inaccurate, invalid, incompatible and corrupt data. Some of those problems are caused by human error during the data entry process, while others result from the use of different data structures, formats and terminology in separate systems throughout an organization.

    The types of issues that are commonly fixed as part of data cleansing projects include the following:

    Data Cleansing Step : Cleaning Up Duplicates

    After standardizing the data format, the next step in data cleaning is to check whether our database has some duplicates that could not be detected earlier due to a different save format.After conducting such an analysis, we discover that in our original database it was possible to find two records with the same tax number: 7540335340 and 754 033 53 40.Our table, after removing duplicates from it, looks as follows:

    The above example is limited to finding duplicates by values in one column. In practice, however, some data defines a unique record with more data arranged in different columns. For example, you can search for duplicated people by first name and last name, and in this case use two separate columns – one for the first name and the other for the last name.

    Build A Data Map For The Target Supplier Profile And Create An Instruction

    Components Data Cleansing Process  Stock Photo © vaeenma #196379600

    The system’s standard supplier profile is not a data map . The typical supplier profile in the ERP/S2C/P2P system provides hundreds of fields in which to store any type of supplier information with the primary purpose of enabling flexibility for fitting in any kind of processes in any sector. In practice, only a small number of fields is typically needed to run a specific business successfully. The designer of the target data model ought to understand both the company and the existing practices, and how these will improve after the transformation.

    The target data map must explicitly indicate what field is for which data element and what fields are not used. Some fields should be used for the supplier’s information, whereas others should be used internally during supplier onboarding and evaluation processes. These include risk level evaluation, approval process, pay priority, and tax classification and others. Moreover, such business information should be specified, although this cleansing is usually performed with input from various business functions, designed logic, and with standard ETL tools. It is unnecessary to contact the supplier and enter business data manually into the system therefore, cleansing of business information is beyond the scope of this article.

    The target data map must be compatible with both the legacy system’s supplier profile and the supplier profile target system. Where field naming differs, the connection between the two must be specified.
