One of those days. Took me an age to find the relevant table. Eventually copped on to myself and reached out to a pal in the US who didn’t even have to look at Resource Descriptions to tell me. For those in the same boat – here’s the answer.
When you create a newDynamics GP Manufacturing Order based on a Sales Order the link information is stored in table IS010001 (ICONrol Sales Order Line). Remember that each sales item line on a sales order will create an individual manufacturing order to make that product. So this table also stores the sales order line item sequence number.
A quick query (where ???? is the manufacturing order number) would look something like:
SELECT SOPNUMBE, LNITMSEQ FROM IS010001 WHERE MANUFACTUREORDER_I = ‘?????’
Additionally table WO010032 (Manufacture Order Master) may contain the Sales Order number in the DSCRIPTN field – if users haven’t overwritten the Description field when the manufacturing order is created.
Hopefully save someone some time!
