Nested Calculated Items in Calculation Group

All,

Fairly new to calculation groups and want to know if the following is possible.

My calculation group has 2 calculated items A and B.  I want to get a percentage, and add a third item C = DIVIDE (A, B). My question is if there is a way to reference the calculation items in the expression for C or do I need to repeat the expression in C, as in DIVIDE ( A expr, B expr).

Reason I ask is for maintainability, if I change A for example, I would need to change the A expression in C, otherwise I would be off. Also, the expression for my B item is quite lengthy and want to keep it easier to read.

Thanks

This was clutch! Thanks @gronnerup

Be carefull of using sideways recursion as it can cause a number of problems. Instead write the full expression again.

But answering you question this can be achived though

``````DIVIDE(
CALCULATE(SELECTEDMEASURE(), 'CalcGroup'[CalcColumn] = "Calc item A"),
CALCULATE(SELECTEDMEASURE(), 'CalcGroup'[CalcColumn] = "Calc item B")
)``````

HI, Did you manage to acheive this? I'm trying to do the same....

Hi @mcolb88 ,

Use Variables.

I undestand the use of variables, I don't want to repeat the expression in the calculation of item C, I simply want to reference another calculated item. Is that possible?

Thanks

You can use one calc item in another in the same group. Just be careful not to introduce infinite loops.
