Automating Time Variable Selection In Information Broadcasting

Hi All,

We have a requirement, where we need to broadcast alive report in Excel format. For this requirement we setup a PreCalculation Server (as we need to broadcast in Excel format). But till now users were using these reports with input ready prompts. Now while scheduling we can create variants for few variables, but not sure how to automate the selection of time fields (Fiscal year; Fiscal Period...).
As users wants those reports be have input ready fields we cannot replace time fields with Customer Exits.

Is there a way that we can automate the Time field selection during broadcasting.

Thanks,

Debjit
