How data in BW cube 0ic_c03 changes ,when materials from different Storage locations moved completely to one storage location in ECC.

Dear BW Gurus

i have a similar kind of problem ,where in ECC  clients are moving materials  from different storage locations to one storage location as they wanted to implement Warehouse management..But already in BW system we have delta loads going to this everyday from BF and UM extractor to 0ic_c03 cube.In this case how to handle the materials shifting to  storage locations in ECC,what would happen to  BW.What kind of data comes in to BW after running the program in ECC.please suggest as i am handling inventory cube since couple of days never worked on inventory.

Example (currently in ECC)

Plant Sloc Material qty

001     01     v0001     4

001     02     v0001     6

After running the program in ECC ,during downtime

Plant sloc Material Qty

001     01     vooo1     10

001     02     v0001     0

What happens to data in BW already.And in which form data is loaded to BW in deltas from same system after downtime.

Thanks in Advance.
