Please make the summary of Time to 'Sum' or 'Same as Main summary'. In the screen shot I can see the Time summary as "Formula" hence the result is based on Top level item's data present in your source module.
It still doesn't provide the needed result. I am thinking that Summary in Anaplan has its limitation/very limiting so I might result to making another module with Quarter only time dimension but I am not sure if its the best practice to do,
MinMax Days Range = Metric Score table applicable (via lookup)
No. of accounts Due = Number of accounts needs to be processed
No. of accounts processed = Number of accounts actually processed
Ratio = Number of Processed over Number of due ratio
Metric Score = Corresponding Metric Score per day range in the MinMax Days metric table (via lookup)
Final Score per Metric = Metric Score multiplied by ratio (to get the weighted score depending on the ratio and metric score)
Final Score per Metric SUM per month is okay since its their score for the month, but per Quarter/Time Summary, the score should be still at Metric Score * Ratio for the quarter hence the FORMULA in Time Summary
Meantime, what I did is, I created a Time range without Quarter totals and use it to calculate every month data then created another module to calculate quarter data. But I keep on trying to do a single module with Quarterly totals because I think that my current idea is not the best practice.
