RFKK_MASS_ACT_PARAMETER autojobs

Hello,

I have a question about the RFKK_MASS_ACT_PARAMETER program. Is it possible to schedule a job which can create a variant every month by changing the date automatically? I managed it to create a autojob for variants, but it will always select the same date and SAP is keep saying that the parameters already exist for that variant.

Thank you!
