In this IMG activity you maintain rules for deriving the partner profit centers in purchasing transactions.
You can derive the partner profit center from any one or more of the following source fields:
Activities
By combining these source fields, you can determine a sequence of derivation steps. To do this, choose Edit -> Choose or Edit -> Create Step
Under Goto -> Maintain rule values you can maintain several derivation rules per derivation step, which the system will process in succession. As soon as a default profit center is found for a derivation rule, the system will add this profit center and will cease processing derivation rules.
It is possible that not all characteristics are set in all postings. If the system does not find a default for a posting in any of the rule values contained in the derivation step, it skips to the next derivation step.
Example
When you buy material M1 from vendor 001 - 100, the system determines that the partner profit center is "PP1"
Preconditions
Profit center involved in exchanges of goods or services between company codes must be defined in all systems. This also applies to profit centers in different controlling areas. Thus in the above example, partner profit center PP1 needs to be defined and must have the same meaning in all affected controlling areas and systems.
Further notes
If you have activated the key figure Display error message for a derivation step under Edit -> Choose on the tab page characteristics, a warning will appear if no rule value is maintained for the current posting. The derivation step will then be ended, and other existing derivation steps will cease to process. To avoid this, enter a rule value for every combination of source values you use.
On the same tab page, you can make a setting so that rule values can be naintained with validity date. This allows you, for example, to deactivate values temporarily for testing purposes without having to delete them.
For more information about maintenance of derivation rules, see the section Profitability analysis (CO-PA) in the R/3 library, under Characteristic derivation.
Notes on Transport
You have to transport derivation rules manually. Choose Extras -> Transport.
