The module also supports tracking the movement of goods and managing inventory levels while optimizing the procurement procedure. But is this why you should migrate your data to SAP MM? Even if you want to, how are you going to do it?

Let’s keep reading to find out more about it.

Reasons to Migrate Data in SAP MM

There are several reasons why you should migrate your data to SAP MM. We have explained three of them here. But if you feel we’ve missed anything, comment below.

1: Ensuring Data Integrity

Data migration can ensure the accuracy and completeness of data transferred from legacy systems or other sources. This helps organizations maintain data integrity and consistency across different systems while increasing productivity. 

2: Minimizing Data Loss

Data migration can also help minimize data loss during the transition from one system to another. By carefully planning and executing the data migration process, organizations can ensure that critical data is recovered during the migration.

3: Supporting Business Processes

The data migration process will also help support business processes by ensuring data is available in the new system as required. This includes information on the inventory, suppliers, customers, and other critical business functions.

Note: Migrating data to SAP MM can take some time to complete. Sometimes, you might have to wait a week or so to get it done. However, we’ll ask you to be patient and, if possible, go for a specialist. With them onboard, the process will undoubtedly be a success.

Migrating Data in SAP MM – A Step-by-Step Procedure

When it comes to migrating your data in SAP MM, it’s a must that you use the right tool and method. Here’s what we usually do when transforming the information correctly.

Step – 1: Planning the Migration Procedure

The first step of any migration procedure is to map the entire process accordingly. This’ll involve – identifying the data you want to migrate, creating a migration strategy, and ensuring the source of data properly. Also, if you have some stakeholders in your organization, be sure to inform them about the plan. This will help you capture the other company-related requirements. And you will be transparent to them from your side as well.

Step – 2: Data Extraction

Once the planning is done and dusted, you must start your journey by extracting the data you want to migrate. It must be performed on the source system by carefully using the tool designed to comply with it. The procedure will include –

  • Identifying the data (that you want to migrate) carefully 
  • Creating the required queries to extract the information accordingly

The extracted data will be saved in a flat-file format such as CSV or Excel to make it easier to clean the same properly. It can be done manually or through a tool.

Step – 3: Cleaning and Preparing the Data 

Before the data can be loaded into the SAP MM system, it must be cleaned and prepared. This involves removing duplicates, correcting errors, and ensuring the data conforms to the required format. Tools such as Excel can be used for this purpose. The data preparation or cleaning procedure should be done in a step-by-step manner. This way, it’ll be easier to find out where you went wrong and take care of it quickly.

Step – 4: Creating Master Data

The next step is to create the master data in the SAP MM system. This involves creating new data records for items, suppliers, and other master data objects. The master data can be created manually or using automated tools such as (Legacy System Migration Workbench).

Step – 5: Loading Data

Once the master data is in place, the next step is to load the transactional data. This involves creating and uploading data files in the SAP MM system. The data files can be created manually or using automated tools such as LSMW. Remember, the time required for this step will be related to the amount of information you’re transporting. So, be patient.

Step – 6: Validating Data

After the data is loaded, it must be validated to ensure it has been loaded correctly. This involves checking for errors, duplicates, and missing data. Various tools, such as Excel, can be used for this purpose. You can also do it manually. But it will take you much time to complete, and you might also make a mistake or two.

Step – 7: Testing

Once the data is validated, the next step is to test the system to ensure that the data is being used correctly. This involves running test transactions and comparing the results with the expected results. If it comes with something negative, return to the beginning and find out where it all went wrong. 

Once the testing is complete, you may take the system and go live with it. It will involve migrating the users to the new system and ensuring that they have access to the required data.
