Create or not create of 0..1 xml structures

Hello all,

I am trying to figure out how to build a mapping which can create a target structure by condition or not.

The target structure looks somehow like this and it's cardinatlity is 0..1:

• Target (0..1)
  • Field_1 (xsd: string 1..1)
  • Field_2 (xsd:string, 1..1)
  • Field_3 (xsd:string 1...1)

I am clear how to map the child fields, but by what way could i create the whole Target structure by a descision (e.g if)

The if else function seems not be able to create nodes.

Did anyone achieve this with a standard mapping function available in the BPMN Process editor.

I am clear i could do it with an "old" PI Mapping (e.g. createIf) and invoke it as Operation Mapping, but that's not the way i am trying to go.

With best regards
