Create variants for RFFOUS_C in ZF21 for company code?

Hi Experts,

I need to create variants for RFFOUS_C. The RFFOUS_C program is run to print checks. This is called directly from the AP payment program, but when you enter the parameters, you must specify the variant to use for each company code. I have to use ZF21 to create the new variants but my colleague did not leave screen shots. I know the house bank and company code needs to be filled out but I don't know any other fields to input, please help!!
