• Message type: E = Error

• Message class: FMCU - Customizing for budgeting in FM

• Message number: 055

• Message text: Account assignment elements optional for posting before BCS activation

<ZH>&CAUSE&</>
&V2& account assignment elements are optional for posting with FM area
&VI&.

System Response

The account assignment elements involved can be set to "Mandatory" in
BCS.
Since at least BCS was activated (&V3&), those accounts assignments are
mandatory for posting.
The activation of BCS is not mandatory and is only checked for certain
programs (which need to choose between BCS and FBS implementation).
It is possible to work with BCS if it is not activated (test phase when
FBS is still the main tool) or if the activation takes place in the
future.
If BCS is used prior to the activation year, an error could occur.

How can this happen?

BCS activation year 2003
Blank allowed for functional area until 2002
For BCS, the functional area can be set to "Mandatory", as it is
mandatory for posting after 2002.
If a posting is done for fiscal year 2002, an error could occur.
If data comes from posting, the functional area could be initial blank.
Therefore it will not be possible to define it for the budgeting
address.
This is considered incorrect by BCS (as the functional area is
mandatory). The posting will be rejected.

How to fix this error?

This is just a warning message.
The risk is minimal, as posting should only update the budgeting in BCS
, after BCS activation.
Addditionnaly, it is possible to derive the value of the optional
account assignment(s), within the derivation tool (dummy value could be
used for fiscal years before the year of BCS activation).
