I am an SAP Data migration consultant who has dealt with the load of master and transactional data in several projects. The purpose of this blog is to explain how the material inventory balance can be loaded in SAP S/4HANA with the new tool Data Migration Cockpit (transaction LTMC).
How inventory balance was loaded with ECC 6.0
With SAP ECC6.0 and previous versions it was common to create an LSMW object that is linked to a recording with transaction MB1C using movement type 561.
The file could include all materials and quantities to be loaded for the inventory balance. This file had to adapt to the file structure defined in the LSMW.
Why approach with ECC 6.0 no longer possible
With SAP S/4HANA this is no longer possible as MB1C is no longer used with SAP S/4HANA.
Besides this, with SAP S/4HANA it is not recommended to use LSMW any more, as there is a new data migration tool called Data Migration Cockpit, which provides file templates that we will fill to perform the data migration.
Steps to load material inventory balance with Data Migration Cockpit
First the consultant has to set the migration key date for the transactional data load and enable that company to transfer the stock. We will see this message when trying to load the file, asking to use transaction SAPFINS_MIG_CTRL.
OSS note 2907958 shows there is a typing error on the long text message. The correct transaction code should be FINS_MIG_CTRL_1 – as I am loading with latest version 1909.
The person responsible of loading the stock needs to fill the load template with the materials, plants, storage locations, quantities and specifying possible different stock types, vendor or customer numbers.
After this it is now possible to load the file for stock with LTMC. The object to use is Material inventory balance.
We need to upload the file with the inventory.
The file needs to be activated.
Now the transfer process can start.
The data will be validated by LTMC.
Some mappings might be needed if not done in previous object loads within the same LTMC project.
Once finished the consultant and the users are able to check the stock has been loaded.
Other SAP ECC6.0 transactions like MB03 are not available any more in SAP S4 HANA, so it is possible to use MIGO to check the material document created with the load. MMBE will show the stock for each material.
As summary, the Data Migration Cockpit tool helps to save time creating recordings and LSMW objects and provides file templates that are easy to fill with the information provided with them.
