Error: Validate with data file failed - Input parameter SELECTION not found

HI,

My requirement is to load actual sale data from BW Cube to BPC Model,

I have created transformation file, while validating the transformation file i am getting the below error.

This kind of activity is being performed first time in the system, So i am suspecting is their some pre-checks or pre-requsites needs to be done?

current version of BPC (NW7.5 Level 0.00)

Thank You,

Sreenath Adapa.
