Measure not picking up tables

[joginderpandha]

Atempting to a simple minus calculation on two fields in a table. 

When I create a measure and go to search the field the intellisense does not recognise any fields but instead only shows all other measures within other tables:

Why is this not allowing me to see all my fields?

Hi @joginderpandha,

As what @JoHo_BI said, measures only take in other measures or formulae such as Sum. If you still have other issue, please share your resouce table and list expected result, or you can share .pbix file for further analysis.

If you want to minus two columns, use a calculated column. Otherwise you'll need to perform some aggregation on the column beforehand, like Sum or Average.

Measures only take in other measures or formulae such as Sum. Give that a try!
