I calcuted the column EntryDate using:

CALCULATE(Min(Table[Date]);ALLEXCEPT(Table;Table[ProducID]))

How can i get the EntryDate's Stock (ie InitialStock) reapeated across all dates.

Also, from that column i need to be able to aggregate by product like so :

A

10

B

4

C

20

Total

34

 

I wonder this can easily be been via DAX.

 

Thanks for your help.

You are going to want something like:

 

InitialStock = MAXX(FILTER(ALL('Table13'),[ProductID] = EARLIER([ProductID]) && [Date] = EARLIER([EntryDate])),[Stock])

That's a column formula.

 

See Table 13 of attached.

Hi,

 

You do not need the Initial Stock and EntryDate columns at all.  This measure will work

 

=SUMX(SUMMARIZE(VALUES(Data[ProductID]),[ProductID],"ABCD",LOOKUPVALUE(Data[Stock],Data[Date],FIRSTNONBLANK(Data[Date],SUM(Data[Stock])))),[ABCD])

 

Hope this helps.

I'm trying to solve this problem but its that I have to find the entry date, not the stock at the entry date. How would I find the earliest date from the ProductIDDate?

 

Thank you!

Thanks. the add column works as excepted but this doesn't aggregates well.
