I have implemented user exit EXIT_SAPLCJWB_004, EXIT_SAPLCJWB_005 to add custom field in CJ20N. Wrote logic in EXIT_SAPLCJWB_005 for updating PRPS Table. Screen got created and table also updated when saving in CJ20N. But if I run the CJ20N transaction again , value is not appearing in the screen for the WBS element which I have saved already. Kindly advise.
