MISSING values IN FRC

Summary:

MISSING values ​​do not work well in FRC reports.

For example, I have a column that has to add two columns, however one of them has a value of MISSING and when I transform it into Conditional Format to 0 for the formula to work, it doesn't work either.

Is there a way to make the MISSING values ​​treated as 0 (zero) so that they work well in the formulas?

I have created a report that shows all the accounts with the Initial Balance, Debit Value, Credit Value and Final Balance

The problem is that there are accounts with a balance of 0 (17100000) FOR  one period, so the Credit works correctly because there is a formula in the Credit Value (IfThen([A]<0,[F],[G])
