Overview allocation method
Check whether assessment can be used instead of periodic reposting, as this leads to considerably better system performance.
- You can use assessment if the origin of the primary costs is not important. If required, you can use multiple assessment cost elements for differentiation.
- Periodic reposting is recommended if the origin of primary costs is important, but the partner object does not need to be displayed directly. The partner information, however, is not lost. Proof of origin is always possible via the line item document.
- If you do need to show the partner object directly in the report, you must use distribution. The data volume will grow significantly for the proof of the partner objects, particularly in large distributions.
Note that the data volume generated for past periods will grow with increased numbers of periods. Especially in reporting and for data backups, it is important to keep the data volume generated by allocation to a minimum. For this reason, assessment or periodic reposting are to be recommended.
For performance reasons, you should not use more than 50 segments in one cycle. If necessary, define multiple cycles. A larger number of segments per cycle is only necessary for extensive iterations.
Also: For performance reasons, never use more than 10,000 relationships in an allocation cycle. If you require more than that, you must plan a mass test of the allocations beforehand.
From a sender cost center with 100 sender cost elements, allocations are made with one segment to 500 receiver cost centers.
The following numbers of sender and receiver totals records result from the different allocations that must be written in the processed period:
|Allocation Sender totals recds Receiver totals recds|
|Assessment 500 500|
|Periodic reposting 100 500 x 100|
|Distribution 500 x 100 500 x 100|
This simple example already demonstrates that
- far more sender totals records are written for distribution than for periodic reposting
- far more receiver totals records are written for periodic reposting than for assessment
In practice, because of the far higher number of senders and receivers, the advantages of assessment and periodic posting are even more apparent.
