如何在SRS中删除表达式中值的负号

Question

FormatCurrency(
(SUM(iif(IsNothing(Fields!Planned.Value),0,Fields!Planned.Value))-(SUM(iif(IsNothing(Fields!Actuals.Value),
iif(IsNothing(Fields!Forecasts.Value),0,Fields!Forecasts.Value),
iif(Fields!Actuals.Value=0,iif(IsNothing(Fields!Forecasts.Value),
0,
Fields!Forecasts.Value),Fields!Actuals.Value))))),
iif(Parameters!DecimalDigits.Value=1,1,iif(Parameters!DecimalDigits.Value=2,2,0)),0,0,0)
)

this is my expression which is returning negative values and how to remove this negative sign in front of the number

Answer 1

The easiest way is to turn the expression around. For instance, if

Planned - Actual

is giving you negative numbers and you want positive numbers then maybe you want

Actual - Planned

Otherwise you could just take the whole expression away from zero to reverse the sign:

0 - <expression>

Or if you really want to kill the negative sign regardless, then use Absolute - this returns the value as a positive number regardless

Abs(<expression>)

I would also remove the formatting part of the expression and put that into the Format property. Almost everything in SSRS can be an expression, so you don't have to do everything in the Value expression.
