How To Fix FKK_CTR008 - Incomplete derivation from field &1: Posting not possible.

FKK_CTR008 - Overview

• Message type: E = Error

• Message class: FKK_CTR - FI-CA: Central Functions

• Message number: 008

• Message text: Incomplete derivation from field &1: Posting not possible.

What causes this issue?

During the document check, the system has determined that the account
assignment in field &V1& has not been derived or has not been derived
correctly for document item &V2&. Before the document check, the account
assignment receives the value &V3& after the checking the value &V4&.
The incomplete account derivation can be due to one or more of the
following reasons:
The function module FKK_FKKOPK_ADD_CO_DEFAULT_DATA that proposes CO
account assignments was not called up or was called up to early.
You have implemented an event in a custom-designed manner during the
posting of the FI-CA document to fill the CO account assignments in
cost-relevant G/L account items such as for example a cost center or a
profit center. You do not derive or incorrectly derive dependent account
assignments such as the business area or segment.
A custom-designed substitution is active in Controlling (transaction
OKC9). The substitution has been called at the same time as account
assignment derivation. The segment or business area were not derived as
designated in the substitution because certain prerequisites were not
fulfilled for the substitution. The substitution has been called up
again during the document check. If the prerequisites for the
substitution are then fulfilled, another derivation is carried out for
the field &V1&.

System Response

You cannot post the document. The segment and business area have to have
already been derived in full at the time of account assignment
derivation.
No other value may be determined at the final check, since changes are
not transferred to the document at this point.
An incomplete account assignment derivation in the segment or in the
business area brings about differences between the totals records and
the G/L documents when the associated reconciliation key is transferred
to the General Ledger because the General Ledger or Controlling derives
this account assignments once again during transfer.

How to fix this error?

Check how the segment or business area is to be filled or from which
other CO account assignments they are to be derived. If a custo
m-designed implementation of an event or a substitution is active in
Controlling, check the implementation.
If the error occurs in an SAP program and you are neither using
custom-designed implementation nor a substitution, please create a c
ustomer incident.

Procedure for System Administrators

You can set the message category for this message by means of the
transaction OBA5 in work area FKK_CTR.
The message is hidden in the standard system, it can however be set in
the dialog or background as an error message. This is advisable if you
repeatedly define the differences in the business area or segment when
the General Ledger is reconciled (transaction FPG2).
A triggered error message prevents the posting from taking place, this
enables you to analyze why the account assignment derivation is
incomplete.
