Job tasks and difference between SAP Consultant and SAP BW Consultant

Hello,

when your working contract is signed as a SAP Consultant (wihtout further specifications of tasks) but your employer wants you to work also as a SAP BW Consultant ... that are to differen positions in my opinion.

I would say both positions are different and the requirements are different also.

Am I correct?

I think the employer doesn`t want to pay more for the new tasks which are necessary for the SAP BW Consultant position.

Best regards
