How to use Variable in message mapping

[Former Member]

Hi Experts,

I have some problem using variable in message mapping.

In one message mapping, since a block of logic is repeated for several fields, then i tried to use a variable instead.

the repeated logic is: first if condition, then use a udf to form a queue which will be suppressed by its father node.

i tried to assign the result queue to a variable after the UDF execution. (this variable is created after the father node)

I am wondering is there any restriction of using variable?

Can we assign the whole queue to a variable?

Can we use UDF during the process of assigning value to variable?

thanks in advance.

Hi,

No, You can not assign the queue to a variable. The occurence of the variable is 0..1.

Thanks,

I dont think you can assign a queue to a variable,I am not 100% sure, . and there is no restriction to useing a Zvariable, only u can use it after you declare at some parent level.

Yes you can use a UDF in the process of assigning to a Zvariable.

Hi Aditya,

Can you please explain the input and expected output of your mapping with some example.

let me give an example, please focus on the variable assignment.

If ifWithOutElse, then give value "true", keep suppress value. then using a UDF to form the queue to another specified queue which i wanted. after that i need to assign the result queue to a variable since it would be used several times.

i tried to use a variable but failed, i want to know the limitation of using a variable.

could anyone help on this?
