Aif Services

For one of Presentation on AIF, I build a custom Document Service based on custom table. To avoid any validation constraints I made a very simple custom table “StudentInfoTable”.

Create a Unique Index on FirstName field, so Read and find method of custom Document service works fine.

In AOT under Query Node with Name AxdStudentInfo, create a new DataSource and add StudentInfoTable. Right click on field and set Dynamic Property to Yes

Now right click on “StudentInfoTable” Node and set its Update properties to true, so Update methods will created against this query object

Now in Development environment from top menu click on AIF frame and then select on Create Document Service and click on it. For this result in running a Wizard

Select following options from Wizard, select the query which we create above mentioned drop down. Name the Document Name

Press Next button, from the next button check all the checkbox as per following screen shot.

Press on Next Button

Press on Generate button.

Press On Finished button.

There is possibility of errors in generated code, You can find complete code generated with wizard in private project in Dynamics Ax.

Right click on AxdStudentInfo and compile again.

You have delete two methods  cacheObject and cacheRecordRecord in AxStudentInfoTable and compile the whole project.

Now right click on StudentInfoService and set namespace

http://schemas.Student.com/ServiceContracts

Now create a right on Service group Node and create a new service group.

Drag and drop service node under Student InfoService group. So  Student Service will be available for in side service group.

Now generate Inc CIL or right click on StudentInfoServicegroup and click deploy

After successful deployment you may find following info box

Now open a new work space and go at System Administration module and open in bound port under Application integration framework

And Open Application Inbound framework

Copy WSDL URL In my case it is

http://WIN-IKPOSIU2SGD:8101/DynamicsAx/Services/StudentInfoServiceGroup

now open Visual studio Project and create a new Console project I am more comfortable with C#.

From Solution explore right click and add Service reference

Now we can use following code to create, Read, Update and delete methods

Create method

  StudentInfoRef.AxdEntity_StudentInfoTable _StudentInfo = new StudentInfoRef.AxdEntity_StudentInfoTable();

StudentInfoRef.AxdStudentInfo _Student = new StudentInfoRef.AxdStudentInfo();

_Student.StudentInfoTable = new StudentInfoRef.AxdEntity_StudentInfoTable[1] { _StudentInfo };

 

_StudentInfo.FirstName = "Ali";

_StudentInfo.LastName = " Raza";

_StudentInfo.Address = " Lahore";

_StudentInfo.DateOfBirth = new DateTime(1979, 4, 6);

StudentInfoRef.StudentInfoServiceClient _Client = new StudentInfoRef.StudentInfoServiceClient();

StudentInfoRef.CallContext _callContext = new StudentInfoRef.CallContext();

_callContext.Company = "USSI";

StudentInfoRef.EntityKey[] entityKeys = _Client.create(_callContext, _Student);

You can see create function works fine.

In above mentioned code, Create method take two parameter, first is Call context, In Call context variable we can define legal entity where data will be inserted.

Read Method

Read method use EntityKey for searching criteria for example we want to search Student with First Name Ali following code will works for Us.

Read method works on keyField value. It is recommend that you will search records on the bases of Unique indexed based field.

StudentInfoRef.KeyField keyField = new StudentInfoRef.KeyField() { Field = "FirstName", Value = "Ali2" };

 

// Create an entity key instance and put in the key field data

StudentInfoRef.EntityKey entityKey = new   StudentInfoRef.EntityKey();

 

entityKey.KeyData   = new   StudentInfoRef.KeyField[1] { keyField };

// Create an array of entity keys and put in the previously

 

StudentInfoRef.EntityKey[] entityKeys = new StudentInfoRef.EntityKey[1] { entityKey };

 

 

StudentInfoRef.StudentInfoServiceClient _Client = new StudentInfoRef.StudentInfoServiceClient();

StudentInfoRef.CallContext _callContext = new StudentInfoRef.CallContext();

_callContext.Company = "USSI";

 

StudentInfoRef.AxdStudentInfo _StudentInfo = _Client.read(_callContext, entityKeys);

 

 

StudentInfoRef.AxdEntity_StudentInfoTable _StudentInfoTable = _StudentInfo.StudentInfoTable[0];

 

Console.WriteLine("First Name :" + _StudentInfoTable.FirstName);

Console.WriteLine("Last Name :" + _StudentInfoTable.LastName);

Console.WriteLine("Address :" + _StudentInfoTable.Address);

 

Console.ReadLine();

Update Method

Update in Document is two step process, first step to read the record based on field and second step to update the record which is return as result.

For example I want to update Address and Last Name of student. Following code works for me.

StudentInfoRef.KeyField keyField = new StudentInfoRef.KeyField() { Field = "FirstName", Value = "Ali2" };

 

// Create an entity key instance and put in the key field data

StudentInfoRef.EntityKey entityKey = new StudentInfoRef.EntityKey();

 

entityKey.KeyData = new StudentInfoRef.KeyField[1] { keyField };

// Create an array of entity keys and put in the previously

 

StudentInfoRef.EntityKey[] entityKeys = new StudentInfoRef.EntityKey[1] { entityKey };

 

 

StudentInfoRef.StudentInfoServiceClient _Client = new StudentInfoRef.StudentInfoServiceClient();

StudentInfoRef.CallContext _callContext = new StudentInfoRef.CallContext();

_callContext.Company = "USSI";

 

StudentInfoRef.AxdStudentInfo _StudentInfo = _Client.read(_callContext, entityKeys);

 

 

StudentInfoRef.AxdEntity_StudentInfoTable _StudentInfoTable = _StudentInfo.StudentInfoTable.First();

 

_StudentInfoTable.Address = "Lahore";

_StudentInfoTable.LastName = "Zaidi";

_StudentInfoTable.action = StudentInfoRef.AxdEnum_AxdEntityAction.update;

_StudentInfoTable.actionSpecified = true;

_Client.update(_callContext, entityKeys, _StudentInfo);

Delete Method

Delete Method works for same way, Send entity keys and call for Delete method.

StudentInfoRef.KeyField keyField = new StudentInfoRef.KeyField() { Field = "FirstName", Value = "Ali2" };

 

// Create an entity key instance and put in the key field data

StudentInfoRef.EntityKey entityKey = new StudentInfoRef.EntityKey();

 

entityKey.KeyData = new StudentInfoRef.KeyField[1] { keyField };

// Create an array of entity keys and put in the previously

 

StudentInfoRef.EntityKey[] entityKeys = new StudentInfoRef.EntityKey[1] { entityKey };

 

 

StudentInfoRef.StudentInfoServiceClient _Client = new StudentInfoRef.StudentInfoServiceClient();

StudentInfoRef.CallContext _callContext = new StudentInfoRef.CallContext();

_callContext.Company = "USSI";

_Client.delete(_callContext, entityKeys);
