Use decision shape when data contains line feeds or carriage return.
You will need to use Matches Regular Expression in decision shape to detect line feeds or carriage return. Matches Wildcards option will not work.
Use Matches Wildcards to match a value on a single line input. To match a value in a multi-line input, use Matches Regular Expression. http://help.boomi.com/atomsphere/GUID-622D5243-D439-4E88-9BEC-418F98396157.html
For the Decision shape, configure it as follows:
First Value: Current Data
Comparison: Matches Regular Expression
Second Value: .*test[\r\n]+.*
