Summary :
When reversing an invoice using Transaction MR8M, error F5802 is displayed, incorrectly stating cleared items prevent reversal; these items were flagged using ALE with IDoc type FIDCMT01 and AUGBL = 'ALE external'. This occurs due to missing checks for 'ALE external' items in reversals. Affecting SAP Releases 3.1I to 4.5B, the issue can be triggered in earlier versions post-implementation of Note 83923. Resolution involves applying a program correction detailed in the supplemental.
