No Spool generated automatically

Hello Gurus,

I am facing one issue with the RSNAST00 program.

I am processing the output for Turkey(invoices) using the RSNAST00 by job, The output was successfully processed and the No spool getting generated atomatically,

This is not the case when i print the Invoice manally from VF02--->issue output., spool generated .

We have our own customized print program and job

Can any one please throw some light on how to resolve this,

Is this Print program issue or RSNAST00 issue?

Expecting your input .

regards,

santosh
