SAP Error Message - Details

• Message type: E = Error

• Message class: UCF3 - Messages for Rounding

• Message number: 009

• Message text: Method step &1: Items in this step do not have the same category

What causes this issue?

You have attempted to assign a set of items to the method in step &v1&.
This specific range of items cannot be processed together for accounting
reasons. This kind of problem occurs, for example, when a selection
range contains balance sheet items from both the assets side and the
liabilities side. Computation of this kind of assignment is not feasible
and therefore invalid.

System Response

The method cannot be executed for the assigned items.

How to fix this error?

Change the definition of the method so that the assigned items for each
selection range reflect a complete and homogenous set of
accounting-related items (such as all asset items in range 1, all
liability and equity items in range 2, and so forth).

Procedure for System Administrators
