Population of custom LIS tables thorugh MFBF transaction

Question

Hello Friends,
I have created a custom LIS tables S728 for Shop floor control (04) and it is updated though REM Backflush (transaction MFBF). But some of the fields are not populated. Can someone help me to understand how this LIS table is populated? I am looking for piece of code where this table is populated.
I see some includes inside main program for MFBF transaction related to LIS structures, but control does not stop there in while debugging MFBF Tran code.
Any direction/suggestion will help.
Thanks.

I added the following code at the beginning of the user exit and was able to prevent the execution of user exit for S031, S032 and S033 during reload of old material documents using OLI1 or OLI2.
DATA: lv_ex_flg TYPE c.
DATA: lfd_string TYPE string VALUE '(SAPLMCB1)XMCINF[]'.
FIELD-SYMBOLS : <fs1> type any,
        <fs2> type any,
        <fs> TYPE table,
        <fs_wa> TYPE any.
IF sy-tcode EQ 'OLI1' OR sy-tcode EQ 'OLI2'.
ASSIGN (lfd_string) TO <fs>.
IF sy-subrc EQ 0.
LOOP AT <fs> ASSIGNING <fs_wa>.
   ASSIGN COMPONENT 'LOW' OF STRUCTURE <fs_wa> TO <fs1>.
   ASSIGN COMPONENT 'HIGH' OF STRUCTURE <fs_wa> TO <fs2>.
   IF <fs1> EQ 'S031' OR
     <fs1> EQ 'S032' OR
     <fs1> EQ 'S033'.
     lv_ex_flg = '1'.
     EXIT.
   ELSEIF <fs2> EQ 'S031' OR
          <fs2> EQ 'S032' OR
           <fs2> EQ 'S033'.
     lv_ex_flg = '1'.
     EXIT.
   ELSEIF <fs2> EQ 'S920' OR
           <fs1> EQ 'S920'.
     EXIT.
   ENDIF.
ENDLOOP.
ENDIF.
ENDIF.
CHECK lv_ex_flg NE '1'.
