Using AX methods for Importing into ATLAS - AX 2012 R2

We are importing data into AX 2012 r2 using ATLAS. We had three fields Color, Size, Style in Excel. Based on these three fields we need to get the InventDimId and import into that field during import. How can we achieve this?


We found InventDimId method in the table we are trying to import. Can we use methods in Atlas to import?
