• Message type: E = Error

• Message class: FMCF -

• Message number: 404

• Message text: FM account assignment of item/acct assgmt &1 is not in multiple selection

What causes this issue?

A parked FI document or purchase order is assigned to several accounts
assigned to different FM account assignments.

System Response

A parked document can only be deleted completely. Likewise, purchase
orders and purchase requisition items can only be flagged as fully
completed.
The program deletes the selected parked document (or closes the
selected document item), even if individual document items (individual
account assignment lines) do not correspond with the FM account
assignments selected and issues a warning in the output list for such
documents/document items.

How to fix this error?

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

Procedure for System Administrators

You can avoid such situations by making sure that parked FI documents
and purchase orders and purchase requisition items assigned to several
accounts are always only assigned to one FM account assignment.
