do you want to say it is in your TVLK table?
I only see this message issued in 1 program: LV05IFIN
And it is just a tiny piece of code to check whether there is an entry in this table:
IF TVLK-LFART NE LLIKP-LFART.
SELECT SINGLE * FROM TVLK WHERE LFART EQ LLIKP-LFART.
IF SY-SUBRC NE 0.
MESSAGE A110 WITH LLIKP-LFART LLIKP-VBELN.
ENDIF.
ENDIF.
