How to create Data type in ESR for a JSON structure in SAP PI?

[resham_naaz]

Hi all

So this might be a very basic question but I am a complete noob in SAP PI right now. I have a requirement where I have a JSON structure like this:

{
"element_one" : "",
"element_two" :[
{
"a" :"",
"b":""
}
]
}

I need to create a data type in the ESR for this structure. What I am confused about is whether I just create it the same way as I do foe XML or JSON without array or does the presence of array requires some additional steps.

Thank you.
