LSMW error for MBST when run in background

Hi experts

I have an LSMW (Bacth input recording) for Transaction code MBST.

When I run in foreground it is OK but when I execute in bactk ground, not successful due to below message:

Field DKACB-FMORE. does not exist in the screen SAPLKACB 0002

Please advise what need to be done to get this issue rectified.

Thanks
