Trip variant for different Fixed per diems in SAP FI TV

Hi Experts,

I am in process of configuring Travel management inhouse. The IMG says for different reimbursement & travel groupings we can create distinct Trip provision variants.

My question is cant we handle by creating one trip variant & creating different reimbursement groups for different set of employee groups.

Please suggest as i am new to Travel Management Module.

Best Regards

Sharma
