VOFM routine configuration

Hi guys,

I have to create a routine for class/group indicator LST1 (Info blocks for RV reporting). In that we need to add a new form to that routine. the form should normally be written in a custom include in RV77SNNN .

So, basically, we would need to have an include for our routine in include RV77SNNN of program SAPRV77S.

Could you please indicate about how to create the required include through VOFM?

Thanks and Regards.
