Inventory Data Loads

Hello Guru,

There is a need and we have to delete all years of historical data in SAP BW and pull it again. I re-searched a lot before starting the steps and found no. of useful documents.

The one I am folloiwng is this one Concept of Inventory Management, Full data loading steps and cleaning process, and Data Testing of Inventory Data in SAP BW.

However, I do have a question.

In the document in Step 2 & 3 author has given different Tcodes to fill set up tables for BF and UM.

2LIS_03_BF using T-code – OLI1BW

2LIS_03_UM using T-code OLIZBW

My question is, Is it Ok if I fill set up tables for Both BF and UM at the same time? or do I need to wait for UM?

Thanks

Prashant
