I´ve got a problem regarding transaction MBRL.
I read in several discussion and also some SAP-Notes that it is possible, to do a vendor return delivery for a material document which is linked to a non-stock material purchase order. I was able to create a return vendor in transaction XK02 and maintained shipping conditions, delivery plant, incoterms and also the necessary partner functions. After that I created a purchase order with account assignment category 'K' for cost center and no material, which is our normal way to do non-stock material purchase orders. When I tried to do MBRL for the material document after MIGO with "Create delivery" checked, I got the error message no. M7279 with the error "Data for creating a delivery is incomplete (Loading Group)".
After some google search I discovered several SAP-notes which gave me some clues about the issue but I´m still not able to get over that error. (622873, 849409, 1011713)
The problem is, that there is no field for the Loading Group in the vendor master data only in the material master data. But I got no material !!!
I hope I was able to give a good overview over that problem and hopefully there aren´t that many mistakes in the text so that u are able to understand the issue and give me some advice.
With kind regards!
