IDOC to inform about posted GR (goods received)

Hello,

I have to create an IDOC when GR is posted to inform another system about this goods movement.

The IDOC that I found is ACC_GOODS_MOVEMENT, but this lools like an IDOC which is used to initiate the GR posting and here I am the other way round.

So, is there any IDOC I can trigger from the output determination to get the expected result?

Or is there a possibility to use an exit where I can build a structure (like Z-idoc) to call here a RFC?

Your help is appreciated!

Best regards

Dirk
