Texas Weather - Same Store Sales only on days open

[Quinnie2017]

Hi Everyone - Could use some help with this problem that I cannot seem to solve:

The Challenge: Need to calculate weekly same store sales only on the days of the week the store was open.

Example: The winter storm last week in Texas is a perfect example.  Here you see that Athens, TX was open Saturday, Sunday and Monday, and closed Tuesday through Friday due to weather:

The problem: The measure [Last Year Sales Same Store] is including [LY Sales] on the days that Athens is closed.

The desired result: The measure [Last Year Sales Same Store] should only include sales on the days Athens is open.  In this case the desired result = $1,711 + $1,788 + $2,041 = $5,600.

Hoping someone smarter than me can get me started in the right direction.  Thanks in advance.  Measure definitions are below:

Same Store Sales Store Count = AVERAGEX( VALUES ('Day Key'[Business Date] ), [SSS Store Count Total])

SSS Flag = 
SWITCH(
TRUE(),
[Store Age at Business Date]>547.501 &&
[CY Sales]>0 &&
[LY Sales]>0,
1,
""
)

Current Sales – Respect Open Close Dates = 
CALCULATE([CY Sales],
   FILTER(SSS,
          [SSS Flag]=1
   )
)

Last Year Sales Same Store – Respect Open Close Dates = 
CALCULATE([LY Sales],
   FILTER(SSS,
          [SSS Flag]=1
   )
)

LY Sales = Calculate([CY Sales], DATEADD('Day Key'[Business Date],-364,Day))

Hi @Quinnie2017,

You can try measure as:

IF(
   HASONEFILTER(Table[Store Name]),
   [Last Year Sales Same Store – Respect Open Close Dates],
   [Last Year Sales Same Store – Respect Open Close Dates])


  

If it does not work, please provide sample data after removing sensitive information.
