CO-PA Derivations
(see
SAP help too)
Used
to populate fields that cannot be populated from the preferred means of
via master data characterisations or original data entry.
Can also be used to convert/summarise historical data into new
groupings.
Transaction: KEDR
– maintain strategy
-
Watch
sequence of derivations
-
Check
if the characteristic has a value already before gaily updating
-
Derivations
must be re generated (extras
> regenerate)
Attributes define when a derivation should be executed
Then
you specify the type of derivation that should take place. A silly
example here aimed at when manual journals are posted to CO-PA. Copy
the customer to the payer field, if the payer field is blank.
Transaction: KEDE
– maintain derivation rules
Another
kind of derivation is the "mapping table" type. The
mappings can be done by users and can be transported, or done directly in
the production system.
You
may need to do a data realignment after updating derivations.
