Conditional mapping

[Romeo Casimina 3]

Hi Gurus,

Is there a way to do conditional mapping in a service task (input to service mapping) I asked because I have service task which follows similar structure as below

Element

|--Element1

| |--Attribute1

| |--Attribute2

|--Element2

| |--Attribute3

| |--Attribute4Element2 is optional while Attribute3 is mandatory. I have two data fields following structure of both Element1 (df1) and Element2 (df2) and mapping it to input to service. What I want to do is check if df2 is null do not map as if I do not have that condition, service task is failing as the API expects that Attribute3 is required if Element2 is present. If I am not mistaken, what is happening is that the payload generated contains Element2 where its attributes are null.
