IDM Attachment Mandatory through extension

shahad · 2025-03-20T07:24:31+00:00

There was an error rendering this rich post.

Can anyone help me to correct the script below? I want to make the IDM attachment mandatory.

long nr.of.documents
nr.of.documents = dom.idm.list.documents.by.attributes("MDS_EntityType","ShipmentRef","MDS_AccountingEntity", "infor.ln.5100","Shipment_Reference",txinh200.orno)
        if nr.of.documents = 0 then
          message("No Attachment found. Please upload and proceed")
        endif

Below is the JSON script from Context Viewer
