I've got a problem with publishing Master Agreement from Sourcing to ERP. In Sourcing, in Document Links appeared an External reference (Agreement in SAP ERP) with wrong title (#1 instead of documents ID). I' ve checked it in ERP and there is no agreement created. Then I used transaction bbp_es_analyze to check if and what kind of data arrived in ERP. There were 3 Line items with Unit Price set as "0". I've deleted them and tried to publish it once more, but then there was another Error: "Internal assigment of number is not defined (please, enter the number)". I think it is connected with that wrong number- #1. Probably deleting this External reference and publishing this MA again should help but i can't delete this. I've already checked forum and found some useful topics e.g. http://scn.sap.com/thread/3234283 but my MA can't still publish in ERP. Do you have any idea what else could I do or how to delete that wrong external reference?
