Pick data from measure

Hi,

I am preparing a forecasting P&L, BS and SOCF position, however, I am stuck in BS. 

For each forecasted year, I have created a "measure" which is based on prior year data multiple by growth rate in case of P&L. Find below query in short which is working perfectly.

Now, I have created another query for BS, which is taking data from previous year balance sheet "Measure" plus current year P&L measure. Below is query 

#FCY1 BS =

 VAR Sales = CALCULATE([#FCY1 PL],PL_Structure[Reporting]= "Sales")

 Var Cost_Sale = CALCULATE([#FCY1 PL],PL_Structure[Reporting]= "Cost of sales")

 VAR PY  = CALCULATE([#FCY BS])

 VAR AR = Sales/365*SELECTEDVALUE('Days - A/c Receivable'[Days])

 VAR NR = Sales/365*SELECTEDVALUE('Days - N/R'[Days])

 VAR Inventories = -Cost_Sale/365*SELECTEDVALUE('Days - Inventory'[Days])

 VAR AP = -(Inventories-Cost_Sale-CALCULATE([@*FCY], 'NL_Structure-BS'[Reporting Category] = "Inventories")/365*SELECTEDVALUE('Days - A/P'[Days])  

RETURN

SWITCH(

    TRUE(),

        SELECTEDVALUE('NL_Structure-BS'[Reporting Category]) = "Accounts receivable",AR,

        SELECTEDVALUE('NL_Structure-BS'[Reporting Category]) = "Notes receivables - current",NR,

        SELECTEDVALUE('NL_Structure-BS'[Reporting Category]) = "Inventories",Inventories,

        SELECTEDVALUE('NL_Structure-BS'[Reporting Category]) = "Accounts payable", AP

      )

Issue:-

I have notice that, this DAX function is not picking any data (Account payable query:

-CALCULATE([@*FCY], 'NL_Structure-BS'[Reporting Category] = "Inventories"

Can anyone help me how to bring open balance from one Measure into another measure?

Thanks in advance.
