Updating financial dimensions for asset table using excel import

Hi All,

In Ax 2012, I have imported some asset table and asset book records without default dimension using excel. Now I got another excel template having dimensions for each asset ID. I have to update each asset table record with the dimension values specified in this template. I am facing problem in creating combinations in related dimension tables.Any suggestions ?

Thanks in advance...
