List of functions used in Dynamics AX 2012 SSRS Reports Expressions

During working in SSRS reports I have to handle division by Zero error for calculating accumulated cost by dividing Amount by Quantity.

 

This expression works for me.

 

IIf(Sum(Fields!xyz.Value) = 0, “N/A”, Sum(Fields!abc.Value) / IIf(Sum(Fields!abc.Value) = 0, 1,Sum(Fields!xvz.Value)))

I did little research on Expressions and function used in these SSRS expressions

 

 

Expressions:

Expressions are used for manipulate or update the value, for example, cost show by dividing amount by Quantity. Rounding of decimal. Similarly Expression can be used to highlight the filed if condition meets. Style font can be changed, even you can uses switch statement, to change the display value of report.

 

Types of Expressions

Globals
Operators – Arithmetic, Comparison, Logical
Common Functions – Text, Date & Time, Math, Inspection, Program Flow, Aggregate, Financial, Conversion, Miscellaneous

We can see each and every one very detail in following.

 

 

Globals

Global expressions executes/works in Page Header and Footer parts only.

ExecutionTime shows date and time at when report executes
PageNumber shows page number of each and every page but allowed only in page header and footer
ReportName displays name of the active report what name we have assigned to the active report
UserId shows current user name like company/alirazazaidi
Language displays language like US-English…

Operators

Arithmetic
^ power of
* multiplication
/ divides two numbers and returns a floating point result
\ divides two numbers and returns a integer result
Mod divides two numbers and returns remainder only
+ adds two numbers and concatenation for two strings
 subtraction and indicates negative value for numeric values
Comparison
Known operators : < <= > >= <> 
Like compares two strings and return true if matched or else returns False. Ex: =Fields!Title.Value Like Fields!LoginID.Value
Is compare two object reference variables Ex: = Fields!Title.Value Is Null
Concatenation
+ and & symbols uses for concatenation
Logical
Known: And, Not, Or 
Xor SELECT * FROM users where firstname = ‘Larry’ XOR lastname = ‘Smith’
AndAlso First condition will check first and if it is true only, goes to next or else it won’t need to check. Because our execution time is saving in a logical operation in which more conditions is combined using AndAlso function.
OrElse same like above
