Ok, this might be a simple question, but say I’ve created a Table of Monthly Sales (columns) by Customer number (rows).

If I have the same 50 customers for a while, so 50 rows, but then I have an import with only 48 customers, or 48 rows, how or will Analytics pick up and place the sales data in the proper customers row and place a 0 in the row(s) where no sales data is for that particular month?

If it didn’t then the sales data would be placed in the wrong customer numbers.
