CJI3 report doesnt display empty/null/zero fields

Hi,

I have added few custom feilds/columns to CJI3 report using:

- Add columns to structure CI_RKPOS.

- Maintain view cluster V_TKALV

- implementing the user exit EXIT_SAPLKAEP_001: Include ZXKAEPU01

If I leave fields blank/space or '0'  fileds doesnt appear on the CJI3 report to select. but if I have some values in it. then it appears.

please let me know how do I display this report with empty column?

Thanks.

Prema
