SAP Note 25782 - Cycle maint.via menu works without auth.

Symptom:

A user only has the authorization "Set operating concern"
Despite this, the user can create cycles or change existing ones via Actual postings, Assessment, Cost center costs, Cycle, Change or Create from Profitability Analysis.
After the new entry or change, the following error message occurs:
No authorization for transaction KEU2.

Cause and prerequisites

Authority check in the wrong place in the program.

Solution
Insert the points indicated by "WKB 11.09.1995.
Also create message KH787 with transaction SE91:
You have no authorization for maintaining cycles
Maintain the long text:
U1 &CAUSE&
AS You have no authorization for the maintenance of cycles.
U1 &SYSTEM_RESPONSE&
AS You cannot perform this function.
U1 &WHAT_TO_DO&
AS Please contact the person responsible for authorizations if you
want to perform this function. The function is protected by the
authorization object: "Profitability analysis: Data transfer into
CO-PA" activity &V1&.

This correction makes sure that cycle maintenance can be called from the initial screen, but that no further screens can be processed.
