Subtract sum of category from a fixed value

[Patryk_PL_92]

Hi All,

looking for help to write DAX formula/measure.

Consider data in table below, there is a Fixed Value (Limit) for each Bank (col B).

Bank may spend money throughout the year.

I need to write a formula which will SUBTRACT sum of "Used Amount" by category "Bank Name" FROM fixed value (from col B)  - it should give me one value, showing what amount is left to be used - then I add it to the bar chart.
X axis - Bank name
Y axis - col B and Sum of col D and amount left to be used (calculated from DAX formula) - each bank will have 3 columns in visual.

I tried to do that on my own, but because this fixed value from col B is duplicated all over the table, then this is a problem for me to cover this exception in the formula.

I know it would be better to keep this fixed value from col B in separate table like:
Bank A - 100mln
Bank B - 500mln

Bank C - 250mln

but this is the data model with which I have to work and I can not change that 😞

Hi @Patryk_PL_92 

Please share the dax formula that you have use? Is it a measure or a calculated column?

What is needed is a measure - single value per Bank Name.

Subtraction between:
[available funds in col B] - [sum of spent cash in col D]

Currently there are no calculated columns in a table, these are raw data from data source.

Formula I used:
1st measure (to calculate how much have we spent in total per Bank):
_SumSpentCash = CALCULATE(SUM(Table1[Used Amount]), Table1[Bank Name])

2nd measure (to get one amount of available funds per bank. There must be a better way to get that fixed value, but I do not have an idea how to... 😞 😞
_AvgTotalAvailableFunds = AVERAGEX(KEEPFILTERS(VALUES(Table1[Bank Name])), CALCULATE(COUNTA(Table1[Available amount for this year]))

3rd measure (final one - it should show how much cash can we still spend, not to go over the fixed limit):
_SubCashLeftToBeUsed = CALCULATE([_AvgAvailableFunds] - [_SumSpentCash])

Hi @Patryk_PL_92 
Before jumping to much more complex formulas, would you please try the following

_SumSpentCash = SUM ( Table1[Used Amount] )

_AvgTotalAvailableFunds = AVERAGE ( Table1[Available amount for this year] )

_SubCashLeftToBeUsed = [_AvgTotalAvailableFunds] - [_SumSpentCash]

Hi @tamerj1 

After your post I just found my stupid mistake in formulas
1st measure should not have the filter parameter

2nd measure can look as simple as yours or:
_AvgTotalAvailableFunds = AVERAGEX(KEEPFILTERS(VALUES(Table1[Bank Name])), CALCULATE(SUM(Table1[Available amount for this year]) / COUNTA(Table1[Available amount for this year]))

Anyway, it works well now
thanks for help 😉
