Mapping error with Graphical Variable

[Former Member]

Hello,

I've problem with mapping.

I want to filled PO_MESSAGE only the first variable that contains data. When is the first works well. If the first is not informed and if the second, the node PO_MESSAGE is not created

What am I doing wrong?

Another thing that surprises me is that when I try display the queue of the variables does nothing happens, this is so in the graphic variables?

Regards,

Silvia

I'm thinking of another way to do this and need help. Using a UDF that receives the 3 variables and return the first one you find informed, how would this UDF code?
