Service connect workflow- Customer shipment

Hi

So i’m building my first service connect workflow with data coming from external database to make customer shipments.
I can successfully make Shiphead, but in the sub-workflow where i loop through shipment rows based on external db query i have problems.
Every net call i have tried will give me “Operation completed successfully” when adding new shipment line, but in reality nothing is written do epicor db. Shipments are in epicor, but with no lines.
I followed trace results, and use the same net calls. Tried Update, UpdateMaster, UpdateExt- all of them give the same results: Operation successful, but nothing really happens.

Has someone done a workflow for creating customer shipments that they would be ok to share, so i can learn where i made a mistake?

Thank you in advance.

Check the tracing in Service Connect, if the correct data flowing in the sub-workflow or not.

Make sure the RowMod has the correct value in it
