If Else statement inside Assign activity for SOA and BPM

Many times we came across situation where we have a singleton variable and we need to assign value to this based on If-Else.
We can write this logic quite easily if we have an XSL or we can have if else activity in SOA/ Gateway in BPM.

We will show you a simple logic to have if-else in Assign activity

Explanation:


Syntax:
concat(substring(<value to be assigned>,1 div (<your if condition>)),substring(<value to be assigned>,1 div not (<same condition written for first substring>))) 


First part marked in Red:
The if condition is evaluated with  1 divided by the expression.If this is true then the value mentioned is assigned (It can be a string or can be a variable).

Second Part marked in Green:
In this case the expression is evaluated with  not condition.This is similar to else statement.If the expression is evaluated to true then value mentioned is assigned.
e.g.:

concat(substring("true",1 div (contains($successFlag,"SUCCESS"))),substring("false",1 div not(contains($successFlag,"SUCCESS"))))

If the variable successFlag contains value Success then the expression will be evaluated as true and then true will be assigned to the variable.If the successFlag contains any other value then 1 div not expression will be true and false will be assigned to variable.

please let us know if code is needed for the same.
