SAP Note 26792 - Allocation: Problems with several cycles, segments

Symptom:

If an allocation with several segments or cycles is carried out (collective execution), this might result in incorrect results.
The following list displays an overview of all problems already discovered in this context:

1. The first segment contains a dimension which does not occur at all in the second segment. Nevertheless, the data is updated in the second segment for this dimension although, by definition, the data is to be summarized via this dimension.
Example:
1. Segment contains the sender dimensions RBUSA, RACCT and RCNTR and the receiver dimension RBUSA.
2. Segment only contains the sender dimensions RBUSA and RACCT and the receiver dimension RBUSA. Although the data is to be summarized via the cost center, the cost center is updated in the 2nd segment (inheritance problem)
This error does not only occur in connection with several segments within a cycle but also with the collective execution of several separate cycles. The reason for this is that an allocation run is regarded as a unit from a programming point of view.

2. With the distribution, the values are redistributed from one account to another account although the account should remain unchanged. This 'incorrect posting' can also occur with any other field.
This error occurs when two or more cycles are started with the allocation collective execution, where one cycle is to process less or other dimensions than another cycle (see above example).

Cause and prerequisites
Solution
Generally, only segments which process the same dimensions should be defined in one cycle. For the collective execution of several cycles, this requirement should also be met for all the cycles.
If errors occur anyway, these can actually only be corrected by distributing the cycles in question, which contain several segments, between several cycles with only one segment.
Since the errors also occur with the collective execution of several cycles, these cycles must then also be started individually.
