Guy,
update on this, not sure why the first time it didn't work correctly but now it is. So for item a I have a PO issued for 100pcs in the purchasing and receiving warehouse 1003, in the inventory warehouse 1000 I have the item requirements set to transfer and warehouse 1003. I changed the SS setting to 3000 and ran MRP, it now shows a planned purchase order for 2,600 pcs which is correct. It also shows a planned transfer which is a new thing, I am not sure what to do with the planned transfer. The transfer is showing 2,777 pcs,.
