Dear SAP Expert,
For Cost base COPA, I would like to define Characteristics derivation as below
Source: VBRK - VBELN ( Billing doc number)
Target: Customized characteristics field
At KEDR, there is no source field VBRK-VBELN available from the drop down.
In this case, how can I specify VBRK-VBELN as a source field?
Best Regards,
Kimiko
