Importing vendors to existing AML entries
Got a weird error and stuck out with knowledge base. I have previously imported AML for a listed of Part numbers via Excel import from spreadsheet method.

Now I want to add in a vendor for those AML lines. I assumed I would be able to just modify this sheet and reimport in.
![]()
Action options from help guide is just add and delete, there is no update.
This is the error message that results, it did validate however:
Description: Description: Specified sourcing status for the manufacturer part conflicts with its existing value
(com.ptc.windchill.suma.ixb.SuMaIxbHndRB/SUMA_AMLPREFERENCE_VALUE_CONFLICT) wt.ixb.publicforhandlers.LogHelper$IxbException: Specified sourcing status for the manufacturer part conflicts with its existing value
There was no row associated with this. I think its telling me that you have an existing entry so I cannot import another one. I tried removing the status but this is required. So what is the process? I should be able to import multiple vendors to a single manufacturer so this import should not fail. Do I have to first delete then re-add? Any anyone done this before?
