In the description from '5.2 Model Build Specifications', we need to calculate the proportion of a country's total sales revenue by product family each account's product sales contributed. The TAR01 was created already in the model, it's dimentioned "A2 Account>Product#' only. However the first line item is to calculate PY Country and Product Family sales, shall I personally add another dimension 'G2 Country' to the module? I tried to calculate it by using DAT02 by referencing SYS03, it was incorrect in anyway "Level mismatch on common dimension". Please help!
