Doubt in defining processing routines through M806

Hi all,

When defining processing routines for an ouput type in M806, there are quite a number of processing options (like processing 1,processing 2 ....processing 5) to provide program, form routine and form names. What is the need for more than 1 processing options? If there are more than 1 processing options i.e. if processing 1 and processing 2 tabs were filled with program name,form routine and form name, how exactly output type will be determined? Pls let me know.

Thanks & Regards,

Vinny
