Facing error with Purchase Requisition workflow approval in AX 2012

Hi All,

I am facing an error with Purchase Requisition workflow approval in AX 2012

I am running Purchase Requisition Workflow. It is running fine till Submission.

When i am clicking on Approval . An error is coming

Stopped (error): Function SysControllerOperation.dobatch has been incorrectly called. Batch group does not exist.”

I have provided all the necessary batch groups.

I am not able to figure out from where this error is coming and how to resolve it.

Can anybody please help in resolving this error.

Thanks in Advance
