I would recommend creating an Import Scenario for AM215000 (Engineering Change Order) and testing it with your sample data first.
If you encounter any issues with the mapping or importing specific fields, please share the details, including the errors you receive and the mappings you have tried. This will help the community better understand the issue and provide more targeted guidance.
I’m sure the community will be happy to help you work through any specific challenges you encounter.
@dales60 ECO and BOM are almost identical. Fastest way would be to Create a new import scenario and insert the mapping from the ACU Import BOM. Add the ECO ID above the BOM ID.
There are a couple date fields and the Requestor field on the ECO that are not on the BOM, but the upper and lower tables are the same. Just re-purpose the data provide for the BOM import, unless you are already using it, of course.
