@alien4u @creece update on my work order script. The record.transform api is is working to create the assembly build and this this also changes the document status on the work order from released to built. The problem now is that I get an error that reads 'Please configure the inventory detail for the assembly item.' This seems to be required to create the assembly build. It seems the inventory detail is not a field, but a subrecord. Can you script with these?
