[Help] - Update UDO using DI Server

[Former Member]

Hi experts, I'm trying to update my record in UDO but I've received this error:

<env:Reason><env:Text xml:lang="en"> [@DOO_OITM.DocNum] , 'Field cannot be updated (ODBC -1029)'</env:Text></env:Reason>

When using Add command. It can successfully add new record.

My UDO is a Document type. Here's my XML for the update:
