SAP Note 27096 - FCS: Costing maintenance routings IA16

Symptom:

In program "SAPLKKCK", the exception "NON_ZERO_DATE_EXPECTED" was triggered by a RAISE statement.
The processing was terminated because the exception is not trapped by a higher-level program in the call hierarchy.

The termination occurred in ABAP/4 program "SAPLKKCK" in "CK_F_CO_OBJECT_PLAN_DELETE".
The main program was "RMIAPL20".

Cause and prerequisites

The interface parameter CKCOUEB_IMP-DATUM is not set due to a missing value in transfer structure CAUFVD-GSTRS

Solution
