Level 2 Sprint 1  1.5.7.2 Add Formula to SYS13 Line Item
Answers

1)The formula should check the total of all product SKU volumes over all time periods
2) check if the value is not equal to zero.
1) You need to use Timesum() function to sum Product SKU volumes over all time periods, Review timesum() function : https://help.anaplan.com/anapedia/Content/Calculation_Functions/All/TIMESUM.html
2) and the result you achieved using that function need to compare using a conditional operator to set boolean value true.

Hi, can anybody please help with this query?
What formula is to be used?0 
IF TIMESUM('DAT03 Historic Volumes'.Volumes) <> 0 THEN TRUE ELSE FALSE

Okay how did we get here?
Reviewing the TIMESUM syntax, the example is:
TIMESUM(TIMESUM line items.Number, 0, 4, SUM)
so my latest try was: TIMESUM(TIMESUM Has Data?, 1, 0, SUM)
which I thought would take data from each line which has a data in the Has Data? Boolean, from the last period (1) to the current period (0) and sum it.
This suggestion
IF TIMESUM('DAT03 Historic Volumes'.Volumes) <> 0 THEN TRUE ELSE FALSE
which works, doesn't seem to fit the syntax to me at all; how does it work?
Also why are we referencing DAT03? Isn't this a filter to be applied?

Both syntax are correct.
In first you are asking anaplan to sum up the values across the time period of the module and then to check where the sum is not equals to zero.
TIMESUM('DAT03 Historic Volumes'.Volumes) <> 0
In below syntax you are using three more arguments(start period,end period and aggregation method) along with Number line items. In current scenario it is not required to have these 3 arguments.
TIMESUM(TIMESUM line items.Number, 0, 4, SUM)

Thanks for this... I also asked in class today and Anees disambiguated this a little bit:
The TIMESUM function ends after the parentheses: TIMESUM('DAT03 Historic Volumes'.Volumes)
The boolean operators <> and value 0 are an IF statement separate from TIMESUM
The final portion is unnecessary as it is the default way Anaplan interprets <>0
So the most elegant solution would be:
TIMESUM('DAT03 Historic Volumes'.Volumes) <>0
Thanks to all!

The timesum function mentioned by vishwajeetg & @swapnil_J are correct, (you can skip the ifstatment when working with booleans if the ifstatment only contains one level (and not multiple nested ifstatments) e.g. "if X then Y else Z")
The issue I think most of you coming to this part of the forum have is that your dimensions missmatch.
Please observe the following in your model. You have two sets of lists both Flat and Hierarchystructured lists.
Make sure that if you have flat list in the DAT03 source, that you use these lists in the Timesum module as well.0
