Repository Context Options Implementation

Complete RepositoryBinding JSON for Step 1

When logging the first O2C event, include this Context Option:

{
  "ExtendedProperties/1.0#RepositoryBinding": {
    "Name": "Order Reception Transport",
    "Service": {
      "Name": "RCV-Order-Incoming",
      "Direction": "Receive",

      },
      "ExternalServiceRelations": [],
      "InternalServiceRelations": []
    }
  }
}

Complete RepositoryBinding JSON for Step 2

This step builds external relations to the previous step:
