Similar issues are because by error "RFC destination not found", or z-error found because of the BBP_ECS_PO_OUT_BADI or BBP_DOC_CHECK_BADI

Suggestion:

• Compare the good and bad PO examples o versions to see if the RFC destination are identical /correct.
• Check if there are Z-errors triggerred in the badi code the when checking the PO.
• To clarify the root cause ,deactivate the badi BBP_ECS_PO_OUT_BADI or BBP_DOC_CHECK_BADI and retest.
• Debug the code above.
• If the issue does not occur in the newly created change version, please delete the incorrect change version (in saved or held status) and create a new one..
