Multiple unique indentifiers or GLN codes...

 
 
Error:
Multiple unique identifiers and/or supplier GLN codes are being used
 
Explanation:
A price list is imported per supplier. The supplier is indicated by means of the SellerGLN. Only 1 GLN can therefore be present per import file.
One price list can be imported per import. Therefore there can only be one PriceListIdentifier in the import file.
If there are multiple values for PriceListIdentifier or SellerGLN, this error message will occur.
 
 
Solution:
Split the import file or change the column PriceListIdentifier and/or SellerGLN so that it contains only one value.
You can check or request GTINs/GLNs at GS1.
