Im trying to import an item, which could be bought at multiple suppliers.
The easiest way is to import into
But for the first step i would like to use the ItemPreferredVendors, AND Business Partner Catalogue Numbers (Identification 73 - substitutional catalog num).
The next step would be a check if the catalog num allready exists, and add this supplier as a preferred supplier.
Any idea's on how to complete this?
Thx in advance
