Separating receipts of category AH by confirmation key "BT" and "LA" for GATP check and BOP

[thomas_schulze2]

Hello experts,

we have a specific requirement for GATP availability checking and wanted to see if someone can help.

Business Case: we use GATP to confirm sales orders for trading goods and run a daily BOP for all open orders. The checking rule control contains receipts of type AH (PO memo). The category AH unfortunately is being used by SAP for 2 different (sub)cases in ERP:

1) supplier sends an order confirmation for the PO --> BF turns to AH in APO (date may change)

2) supplier sends a shipping notification for the PO --> AH remains AH in APO (but the date may change)

Now we want to use the AH elements for ATP which are of my 2nd case only (supplier has send a shipping notification after processing the Goods Issue) but not the ones of type 1). There are multiple reasons for this but the primary argument is that the environment with the external sourcing is fairly volatile and the region/location wants to use only the date of the AH element as a valid receipt once the shipping notification defines the receipt date - but not the order confirmation from the supplier on the AH element - which is of no good quality.

I've not seen an easy separator on AH elements in APO (if you check RRP3 for example) to identify if it is of case 1) or 2). If someone has an idea of how to separate them - next question is how do I tell the ATP check to ignore the "unwanted" AH elements. SPRO for GATP has no explicit enhancement spot mentioned where I can influence the receipts side of the ATP controller.

Thanks for any hint !

Regards

Thomas
