uploading vendor master data using std.batch input program in lsmw.
here while uploading partner function data from flat file,
for partner function VN ,i am getting the error message as
partner function VN(vendor) must be unique in vendor master record.
only by having a manual interaction we can continue the process.
so,without manual interaction how could i solve this problem.
Sounds like you try to assign partner role VN more than once to a vendor. This is not allowed by your customizing settings.
If this is the reason, then solution is: don't upload multiple VN partner roles.
