Thank you, the only field I was missing was the Sequence of the Scheduled resource aka ECOOpDtl#OpDtlSeq
Once I added that in with 10 for all since that’s what they are, it would update them correctly. I wish there was an error stating I was lacking info for the field to update properly.
Well, this was one of the more difficult ones to get templated correctly as I recall when we loaded all the MoMs in the Custom division.
Went from DOS based DB with mostly a flat bill to Epicor I created a few spreadsheet tools to enable easier creation of indented BoMs I would auto convert to flat DMT template that loaded straight into Epicor
