Creation of the new case

After the case worker enters the data for the case, the final step in creating a case is to add the case to the repository. The external data service is called again to validate the data.

The following steps show the flow of data when a case worker adds a case to the repository:

The case worker finishes updating the case properties and clicks Add.

Case Client submits the working property values to the IBM® Business Automation Workflow REST protocol by calling the POST method of the cases resource:

POST /CaseManager/CASEREST/v1/cases
{
  "TargetObjectStore": "CMTOSDH", 
  "CaseType": "DH2_MyCase", 
  "ExternalDataIdentifier": "1,1", 
  "Properties": [

    // Non-external data related properties

    {
      "SymbolicName": "CmAcmCaseIdentifier", 
      "Value": null
    }, 
    {
      "SymbolicName": "CmAcmCaseState", 
      "Value": 0
    }, 

    // ...

    {
      "SymbolicName": "DH2_State", 
      "Value": "CA"
    }, 
    {
      "SymbolicName": "DH2_PropOne", 
      "Value": 7
    }, 
    {
      "SymbolicName": "DH2_City", 
      "Value": "San Diego"
    }, 
    {
      "SymbolicName": "DH2_MVInt", 
      "Value": [
        0, 
        101, 
        200, 
        210
      ]
    }, 
    {
      "SymbolicName": "DH2_MVString", 
      "Value": [
        "One", 
        "Three", 
        "Thirty"
      ]
    }
  ]
}

The IBM Business Automation Workflow REST protocol submits the property values to the external data service by calling the POST method of the particular object type resource:

POST /testservice/ICMEDREST/type/DH2_MyCase
{
  "repositoryId": "CMTOSDH", 
  "requestMode": "finalNewObject", 
  "externalDataIdentifier": "1,1", 
  "properties": [

    // Non-external data related properties

    {
      "symbolicName": "CmAcmCaseIdentifier", 
      "value": null
    }, 
    {
      "symbolicName": "CmAcmCaseState", 
      "value": 0
    }, 

    // ...

    {
      "symbolicName": "DH2_State", 
      "value": "CA"
    }, 
    {
      "symbolicName": "DH2_PropOne", 
      "value": 7
    }, 
    {
      "symbolicName": "DH2_MVInt", 
      "value": [
        0, 
        101, 
        200, 
        210
      ]
    }, 
    {
      "symbolicName": "DH2_MVString", 
      "value": [
        "One", 
        "Three", 
        "Thirty"
      ]
    }, 
    {
      "symbolicName": "DH2_City", 
      "value": "San Diego"
    }
  ]
}

The external data service responds with values for the properties that it manages:

{
  "externalDataIdentifier": "1,1", 
  "properties": [
    {
      "symbolicName": "DH2_State", 
      "required": true, 
      "maxLength": 2, 
      "hasDependentProperties": true, 
      "choiceList": {
        "displayName": "StateChoiceList", 
        "choices": [
          {
            "displayName": "New York", 
            "value": "NY"
          }, 
          {
            "displayName": "California", 
            "value": "CA"
          }, 
          {
            "displayName": "Nevada", 
            "value": "NV"
          }
        ]
      }
    }, 
    {
      "symbolicName": "DH2_PropOne", 
      "maxValue": 10, 
      "minValue": 1, 
      "hasDependentProperties": false
    }, 
    {
      "symbolicName": "DH2_MVInt", 
      "maxValue": 1000, 
      "minValue": 0, 
      "hasDependentProperties": true
    }, 
    {
      "symbolicName": "DH2_MVString", 
      "required": true, 
      "maxLength": 24, 
      "hasDependentProperties": false, 
      "choiceList": {

        "choices": [
          {
            "displayName": "One", 
            "value": "One"
          }, 
          {
            "displayName": "Two", 
            "value": "Two"
          }, 
          {
            "displayName": "Three", 
            "value": "Three"
          }, 
          {
            "displayName": "Twenty", 
            "value": "Twenty"
          }, 
          {
            "displayName": "Thirty", 
            "value": "Thirty"
          }, 
          {
            "displayName": "Fourty", 
            "value": "Fourty"
          }
        ]
      }
    }, 
    {
      "symbolicName": "DH2_City", 
      "hidden": false, 
      "required": true, 
      "hasDependentProperties": false, 
      "choiceList": {
        "displayName": "CityChoiceList", 
        "choices": [
          {
            "displayName": "Los Angeles", 
            "value": "Los Angeles"
          }, 
          {
            "displayName": "San Diego", 
            "value": "San Diego"
          }, 
          {
            "displayName": "San Francisco", 
            "value": "San Francisco"
          }
        ]
      }
    }
  ]
}

The IBM Business Automation Workflow REST protocol validates the values that are submitted by the Case Client with the final external data constraints. If no errors occur, the protocol creates the case and returns details for the new case:
```
{
  "CaseTitle": "DH2_MyCase_000000100602", 
  "CaseIdentifier": "DH2_MyCase_000000100602", 
  "CaseFolderId": "{7F390468-7FAD-43EB-B373-675D2255BB61}"
}
```
