Using Data Manager Prompt Values in Transformation files

Hi,

My requirement is to load data from a flat file into the BPC Cube. Now for the time dimension I need to take the values from the user in the Data Manager (DM) prompt.

After that I need to take the first 4 digits of the time that the user enters and append it with .INP and save it to the time dimension.

For e.g. When I run the DM and give 2013.TOTAL in the prompt, then the value getting saved should be 2013.INP.

Now my question is, how can i use the selection value of the prompt of a DM in my transformation file in order to achieve this.

I am using the Import Transaction Data DMP. Environment is SAP BPC NW 7.5

Cheers,

Nitin
