How To Fix CNV_PE435 - Grouping would lead to the creation of multiple documents

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_PE - General messages for posting engine

• Message number: 435

• Message text: Grouping would lead to the creation of multiple documents

What causes this issue?

Function module AC_DOCUMENT_GENERATE is theoretically capable of
creating multiple FI documents at once. However, this is not supported
by the Posting Engine.
The Posting Engine supports 1x1 and Nx1 assignments of worklist item(s)
to FI document, but 1xN or NxM is not supported.
The system found that grouping each transfer list (of all worklist items
belonging to the same group ID) into one single grouped transfer list,
would lead to different values (&V1&, &V2&) in field &V3&. This however
would lead to the creation of multiple FI documents.

System Response

Error

How to fix this error?

Change the defined transformation so that field &V3& has the identical
value for all worklist items with the same group ID.
Alternatively you can deactivate <ZK>Grouping</> for this transfer
method. Then you can process each worklist item individually.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
