Hello GTSizans,
I have observed a gap in SAP GTS SPL functionality. If we manually change the BP address in a document in ECC system, then it overlooks the negative list entry or block for the BP in GTS.
That means if a business user changes the ECC document address, it generates a new address number in GTS system & hence it overlooks negative list entry for this BP and also BP block.
So by changing the address we may erroneously do a transaction with a blocked partner or negative list partner. Unfortunately no solution available in standard SAP GTS.
