Dear Community, 

I would like to ask you, maybe you know the answer to our problem.

We try to establish API communication between Apps10 (Update and Dell Boomi. We have issues with updating PO header and lines.
IFS update methods are not working. We tried the Purchase Order Handling methods:
for PO header update -">" Update PurchaseOrderSet
for PO no part line update -">" Update PurchaseOrderSet-">"LineNopartArray
for PO part line update -">" Update PurchaseOrderSet-">"LinePartArray

The projection is on, we tried the Create methods and they are working fine.

I checked this page: 

but this was not help.

Thank you very much in advance of any suggestion!

Best regards, 

Balazs
