SAP Note 16055 - RFWEKO00 does not select anything

Symptom:

RFWEKO00 does not select anything.

Cause and prerequisites

The different reconciliation account for notes receivable (e.g. 125000) is defined without line item display (SKB1-XKRES), which means no BSIS is written, and no BSEG is selected as a result.

Solution
Define the reconciliation account with line item display (using transaction FS02).
