Error occurring while using Export Import functionality for bill of material in Windchill 11. Importing modified bom after replacing an item in the bill of material throws an error as attached. Please find the BOM also attached. I had raised this issue earlier also when we were using Windchill 10.2 but at that time PTC closed the case saying that this issue is fixed in Windchill 11 and can not be done in Windchill 10.2. Please resolve the issue ASAP as this functionality helps in reducing the time for BOM change by a huge amount.
