how do I build the formula in 'Sys01 time settings by week' for this line item i was looking at currentperiodstart and comparing it with start... cant quite figure out the relationship0

if this doesn't answer your question, it might be helpful to attach a couple of pictures. But, to return the first period of the timescale, you can use the LAG function formatted as a bolean.

You need to get the current week against week dimension in a line item and keep the summary as "First Non-Blank" - It will set the value at all time periods=First Week of Time scale. Here are the two line items:
The formula for boolean is: ITEM(Time) = First Week of Timescale[SELECT: TIME.All Periods]
Hope, this is what you are looking for.

The learning materials hinted offset function
should i use offset(1,-1,0) = 0

what if first week of timescale is set as a Boolean?

No, with LAG and if you want to go back, you use a positive 1 as what I showed above. If you use negative 1, it will go into the future (like a LEAD).

Yes - that would the result. Line item names in the screenshot, I shared are somewhat misleading.
Line Item 1 - We can name it ItemWeek - dimensioned to Time - week
ItemWeek= Item(Time) - Summary would be first non-blank
Results of this would be:
Week 1 Week 2 Week 3 Week 4 ________________ All Periods ItemWeek Week 1 Week 2 Week 3 Week 4 ________________ Week 1 First Week of Time Scale? : ItemWeek=ItemWeek[Select: Time.All Periods]
This would only be true for Week 1.
Hope, this answers.
