Good Morning Bernard,
Hm Tabelbuffering. Try to update for test changed record by changed record

SELECT Final
SET ASSERT ON
lnRec = GETNEXTMODIFIED(0)
DO WHILE lnRec>0
 GO (lnRec)
 llRet = TABLEUPDATE(.T.) MESSAGE 'Problem'
 IF !llRet THEN
  lcModifi = GETFLDSTATE(-1)
  ASSERT .F.  &&you may stop here
 ENDIF
ENDDO

Check the Record with GETFLDSTATE(-1) to see what it shows.

Please post the string out of lcModifi, so I can see better whats up.
