Hello, since this is Assumed Answered I would like to restate the question and get your feedback.
I understand that SAP has provided a BAdI named Define Document Type for Reduction by Other Documents (FMFR_ALLOW_DOCCATS) which makes it possible to define which earmarked funds documents (Reservations, Precommitments or Commitments) can be reduced by follow-on FI or MM documents.
Has anyone used this approach to allow reducing Precommitments from POs?
