Why doesn't Salweek.pc roll up Margin Cost Variance ?

Hi,

On the ORMS system (version 13.1.2.4) I'm working on, the daily rollups (saldly.pc) get tran_code 72 records

(Cost Variance – Cost Accounting) - and roll them up correctly into DAILY_DATA table as margin_cost_variance.

However, on the weekly rollups (salweek.pc), although being included in the open stock position, the margin_cost_variance is null.

Checking the code, I noticed that the update instruction for the daily rollups correctly picks up and populates the margin_cost_variance,

but on the weekly rollups, this field is not used/updated.

I noticed that on the monthly rollups the field is fetched again, but from daily_data, which leads me to believe that there is some reasoning behind this, and is not a simple omission.
