Hello Vincenzo,
i strongly recommend to not use this Business Function if the standard design does not cover the customer need.
We still have standard bugs not solved by SAP for months regarding:
- Account Assignment,
- UWL,
- Reason for rejection,
- Internal note not changeable for free-text,
- Approval process not correctly displayed when SC ordered/saved
and so on...
