SPOOL not generated while smartform is executed in Background

Hi

I have issue while creating spool for smartform in background.Its works fine in foreground and i m able to view the outpt.

But in background it should generate a spool but it is not generating?

I have given the ouput options to supress the dialog but it still it is not generating the spool.

control-preview = 'X'.

control-no_dialog = 'X'.

control-device = 'PRINTER'.

control-no_dialog = 'X'.

control-GETOTF = 'X'.

OUTPUT_OPTIONS-TDDEST = 'LP01'.

OUTPUT_OPTIONS-TDNOPRINT = 'X'.

Any suggestions??

Thanks & Regards
