Circular Dependency

[M_SBS_6]

Hi, 

I have two measures: 

Measure One:

Total_mort_a =

Calculate(

Sum( 'comps'[comp_value]),

'comps'[mort_id] in {"A"})

Measure Two:

Total_mort_d =

Calculate(

Sum( 'comps'[comp_value]),

'comps'[mort_id] in {"D"})

I have then created a column (as I need to SUM this later) with the following logic:

Exclusion_for_mort_a =

If('comps'[comp_exclude_flag] ="Yes",'comps'[Total_mort_a],

If('comps'[app_exlude_flag] ="Yes",'comps'[Total_mort_a],

If('comps'[fa_exlude_flag] ="Yes",'comps'[Total_mort_a],0)))

All of the above so far, works perfectly.

I have then tried to replicate the same logic for Exclusion_for_mort_a but this time, for the Measure total_mort_d

Exclusion_for_mort_d=

If('comps'[comp_exclude_flag] ="Yes",'comps'[Total_mort_d],

If('comps'[app_exlude_flag] ="Yes",'comps'[Total_mort_d],

If('comps'[fa_exlude_flag] ="Yes",'comps'[Total_mort_d],0)))

But for this Measure, I get the error message:

Circular dependency comps[column], comps[Total_mort_a], comps[column]

I'm really confused as to why this is a problem as I have 2 separate measures for mort_a and mort_d.

Can anyone please point me in the right direction as to how I resolve this please?

The first thing to do is to rewrite the calculated column so that it doesn't use measures.  I see people doing this all the time and it's not a good idea.

You may still experience a circular dependency after this but you will be able to track why it's happening
