Can I assign diffierent GL to movement type 601(GI) and 459(return to bl ?

dear friends,

we have GL50000 (cost of goods sales) assigned to both movement type 601(goods issue) and 459( transfer posting from return to bloked stock).

My question is :

1. Can I assign different GL to these two types of goods movement?

2. in which configuration can I find movement key , such as 601 behind a transaction, such as goods issue?

Your advice will be deeply appreciated.

Thanks,

Linda
