Workflow Issue - Delivery address XML Reference workflow - Error

Hello All,

I am an ABAP developer, with very limited knowledge in Workflow, and I am stuck with an ongoing issue for quite sometime. We have a scenario where we need to a workflow triggers for a specific UNDATED sales order lines (identified by values in VBAP-Zfield ) in R/3 box, and it carries an XML request (probably mails it) to a SAP CRM destination, which would now update some CRM tables and generate a Call list in the SAP CRM box. This is one flow that used to be fine, but has stopped working since the past few months may because of some change, which is not yet identified. as multiple projects are working on the same boxes.

To elaborate -

1 - We have a SALESORDER_CREATEFROMDAT2 Idoc creating the SO, where in, based on a CUTOFF date condition, (if it is in the past), a VBAP-ZFIELD for the corresponding line is set to a value (08).

2 - This event is expected to trigger a workflow for the Undated order/Delivery resolution , which would then create an XML doc for the SO and send this across to CRM box

3 -This will then update a Ztable. This will be handled by a batch job in CRM to generate a call list.

Now we are facing a problem in the second step here, where in the activity - 'BCKGRD: Create XML_DOC for SO: xxxxxxxx' is completing successfully, but having a failure in the next step  - 'Delivery address XML Reference workflow - ERROR'

This is how the detailed workflow log looks -

I've also attached a screenshot for the errors, if that gives a clue.

Request all the workflow experts to help me with a solution, or an approach towards a fix.

Thanks & Regards,
