hi,
Exemple:
3PL storage location = 3000
Plant storage location = 2000
Plant storage location for STO = 1000
You do your STO from 3000 to 1000.
You can define your special GR process with a special WM movement that goes from storage type 902 to A01.
Then you move the goods with LT09 into B01 and this will automatically do a transfer from storage location 1000 to storage location 2000.
When you do a purchasing for storage location 2000, hen you do a normal 902 -> B01.
