Link condition
A link condition control the execution of tasks in the work flow define the link condition using following pre define variable “status”.
Procedure
Create a 3 mapping with the name m10, m20. m30
Create a 3 session with the name s10, s20, s30
Create a work flow drop the session besides the start task in a sequential passion make a link between tasks
Double click on the link between s10 and s20
From pre defined tab double click on the variable status
Define = succeded
Click on variable
Similarly defined the link condition between s20 and s30 session tasks
