I am working on profitability analzsis.I have searched in sdn and i am able to create the derivation rule.
But i am not understanding how it will works and what is the purpose of this.
Can anybody please let me know how derivation rule works in COPA.
Derivation rule contains the parameters and conditions as to how to derive a value for a given characteristic.
Source Fields - from where the source field is originatingand the field name
Target fields - contains what is the target field in COPA for the relevant source field.
This field is nothing but the charactiristic.
When an SD document is posted, system will look for all the characterics available in the doucment like plant, profit center, division, district, country etc
for each of these characteristics, there must be values for example plant - xx18, profict center - 100000, district - bangalore, country - India etc.
once we define the characteristic values for each of the characteristic, if the values in the document are available in the characteristic value definition, then system will fetch these values to COPA
Else it will throw error that characteristic value is not defined
I hope your question is clarified
