What you are passing in Invoice indicator ?
- INVOICE_IND- If you are posting a credit memo it should have value as 2.
1. I'm not sure which material document to choose. I have two GR entries available, one is with movement type 101 and the other one is with movement type 122.
I think only use 122 when Invoice is not posted. You post credit memo for movement type 161 which with reference to return po created separately.
If you still want to post credit memo Invoice_Ind = 2.
But what you will do the material document that have 102 in it ?-- that is cancellation of 101 document ?
101- You can post invoice with Invoice_ind=1
2. If there were multiple Goods Receipts, how do I submit them to the bapi ?
Do I need to submit two records in ITEMDATA parameter for the same PO line with different Goods-Receipt reference?
Do you have GR-IR Indicator checked in the PO - then I would recommend one document at a time..
Do you try to post multiple even you do not have GR-IR indicator checked. This will make easy to trouble shoot and document mapping.
3. If there were multiple Goods Receipts, how do I know if an vendor credit invoice has been created for the Goods Receipt document in the past?
You can check PO history table EKBE. It have various You have to pass indicator as 2- Invoice receipt. When you validate indicator -SHKZG= H .. means that number is credit memo .. in RSEG table of invoice number you find material document number -LFBNR and LFGJA as well as LFPOS
