Merging two arrays

Hi @manohar ,

After the input data you can use JSON Splitter to split the input data on $order-lines, then simply use Group by N with the following

Result:

[
  {
    "order-lines": [
      {
        "line-num": "00010",
        "attachments": {
          "type": "AttachmentText",
          "intent": "Supplier",
          "text": "2021-08-25 09:57 :-  Test"
        },
        "description": "Test 31103"
      },
      {
        "line-num": "00020",
        "description": "Test 31104"
      },
      {
        "line-num": "00030",
        "description": "Test 10220"
      }
    ]
  }
]

This is assuming you have only one data source, if you have two then use Join with following setting

After this use Mapper with the following expression

You get the same result.
