emeadaxsupport: Calling the Update Operation on Services in AX 2012

==============

Calling the update operation on web services can range from simple
to very complicated depending on the entities/tables you are updating. If the entity you are calling is not a date
effective entity, then the service's update method is easy to call.

You can tell if a table is date effective by going in the
AOT to the Data Dictionary > Tables > Find the tables that comprise the
service > Right-click on the table and choose Properties. In the property sheet, look for the
ValidTimeStateFieldType property. If the
property is set to "None" then the table is NOT date effective. You will need to look at every table in the
service to see if that property is set to none.

If the service is not date effective, like the sales order
service, then you can call the service using the find and then the update operations. In the example below, I retrieve a sales
order using the find method and then I update the SalesQty and SalesPrice
fields on each sales line in the retrieved sales order.

static void Main(string[] args)

{

//First find the order

AxdSalesOrder salesOrder = Program.FindOrder();

//Now update it

Program.UpdateOrder(salesOrder);

}



static AxdSalesOrder FindOrder()

{

CallContext context = new CallContext();


context.Company = "ceu";



string salesId = "SO-101244";

AxdSalesOrder foundSalesOrder = null;



//Instantiate an instance of the service client class

SalesOrderServiceClient proxy = new SalesOrderServiceClient();



try

{


foundSalesOrder = proxy.find(context, Program.createQueryCriteria(salesId));


Console.WriteLine("The sales order was found.");

}

catch (Exception e)

{


Console.WriteLine("The sales order was not found.");

}



return foundSalesOrder;

}



private static QueryCriteria createQueryCriteria(string salesIdValue)

{

CriteriaElement[] criteriaElements = new CriteriaElement[1];


criteriaElements[0] = new CriteriaElement();


criteriaElements[0].DataSourceName = "SalesTable";


criteriaElements[0].FieldName = "SalesId";


criteriaElements[0].Value1 = salesIdValue;



QueryCriteria queryCriteria = new QueryCriteria();


queryCriteria.CriteriaElement = criteriaElements;

return queryCriteria;

}



static void
UpdateOrder(AxdSalesOrder salesOrder)

{

CallContext context = new
CallContext();


context.Company = "ceu";



SalesOrderServiceClient proxy = new SalesOrderServiceClient();

foreach (AxdEntity_SalesTable
salesTable in salesOrder.SalesTable)

{


foreach (AxdEntity_SalesLine
salesLine in salesTable.SalesLine)


{

salesLine.SalesQty =
salesLine.SalesQty + 1;

salesLine.SalesPrice =
salesLine.SalesPrice + 2;


salesLine.SalesPriceSpecified = true;


}

}



try

{


proxy.update(context, Program.createEntityKeyList(),
salesOrder);


Console.WriteLine("The sales order was successfully updated");

}

catch (Exception
e)

{


Console.WriteLine("The sales order was not updated.");

}

}



Unlike the sales order service, the customer service is date
effective because it contains the DirPersonName, DirOrganizationName,
DirPartyLocation, etc. tables which have their ValidTimeStateFieldType
properties set to something other than None.
Date effective services have properties added at the document level (the
highest level in the service) to indicate how you want to set the date effective
entities. The properties are ValidTimeStateType,
ValidAsOfDateTime, ValidFromDateTime and ValidToDateTime. Either you can set those at the document
level or you can set the date effective fields on each entity in the service
that is date effective. In the example
code below, I call the read method to retrieve a customer and then I create a
new instance of a customer, set the date effective properties on the document according
to what they are on the retrieved customer and then update the CreditMax field
on the customer.



static void
Main(string[] args)

{

string customer = "1104";

AxdCustomer foundCustomer = null;

CallContext context = new
CallContext();


context.Company = "ceu";



CustomerServiceClient proxy = new CustomerServiceClient();

try

{


foundCustomer = proxy.read(context, Program.readCritera(customer));


Console.WriteLine("Read worked");



Program.updateCustomer(foundCustomer);



}

catch (Exception
e)

{

Console.WriteLine(e.Message);

}



}



private static
EntityKey[] readCritera(string customerAccount)

{

AxdEntity_CustTable custTable = new AxdEntity_CustTable();

EntityKey[] entityKeyList = new EntityKey[1];

EntityKey key = new
EntityKey();

KeyField[] keyFields = new
KeyField[1];

KeyField keyField = new
KeyField();


keyField.Field = "AccountNum";

keyField.Value = customerAccount;


keyFields[0] = keyField;


key.KeyData = keyFields;


entityKeyList[0] = key;

return entityKeyList;

}





private static void
updateCustomer(AxdCustomer customer)

{

CustomerServiceClient proxy = new CustomerServiceClient();

CallContext context = new
CallContext();


context.Company = "ceu";



AxdEntity_CustTable custTable =
customer.CustTable[0];



AxdCustomer axdCustomer2 = new AxdCustomer();


axdCustomer2.ValidTimeStateType = customer.ValidTimeStateType;


axdCustomer2.ValidTimeStateTypeSpecified = true;


axdCustomer2.ValidAsOfDateTime = customer.ValidAsOfDateTime;

axdCustomer2.ValidFromDateTime =
customer.ValidFromDateTime;


axdCustomer2.ValidToDateTime = customer.ValidToDateTime;



AxdEntity_CustTable custTableNew = new AxdEntity_CustTable();


custTableNew._DocumentHash = custTable._DocumentHash;


custTableNew.RecId = custTable.RecId;


custTableNew.RecVersion = custTable.RecVersion;


custTableNew.action = AxdEnum_AxdEntityAction.update;


custTableNew.actionSpecified = true;


custTableNew.CreditMax = custTable.CreditMax + 10;


custTableNew.CreditMaxSpecified = true;


custTableNew.CustGroup = custTable.CustGroup;




axdCustomer2.CustTable = new AxdEntity_CustTable[1] { custTableNew };



try

{


proxy.update(context, Program.readCritera("1104"), axdCustomer2);


Console.Write("Worked");


Console.ReadLine();

}

catch (Exception
e)

{


Console.WriteLine("Failed");


Console.ReadLine();

}

}



As an alternative to setting the properties at the document
level (AxdCustomer) I can set the date effective properties on each table in
the service that is date effective. As
you'll notice the code get clunkier and more difficult to do programmatically. The example code below accomplishes the same
goal of retrieving the customer using the read method and then it updates the
CreditMax for that customer.



static void Main(string[]
args)

{

string customer = "1104";

AxdCustomer foundCustomer = null;

CallContext context = new
CallContext();


context.Company = "ceu";



CustomerServiceClient proxy = new CustomerServiceClient();

try

{


foundCustomer = proxy.read(context, Program.readCritera(customer));


AxdEntity_DirParty_DirPartyTable
returnedPartyTable = foundCustomer.CustTable[0].DirParty[0];


Console.WriteLine("Read worked");




Program.updateCustomer(foundCustomer);



}

catch (Exception
e)

{


Console.WriteLine(e.Message);

}



}



private static EntityKey[] readCritera(string
customerAccount)


{


AxdEntity_CustTable custTable = new AxdEntity_CustTable();


EntityKey[] entityKeyList = new EntityKey[1];


EntityKey key = new EntityKey();


KeyField[] keyFields = new KeyField[1];


KeyField keyField = new KeyField();


keyField.Field = "AccountNum";


keyField.Value = customerAccount;


keyFields[0] = keyField;


key.KeyData = keyFields;


entityKeyList[0] = key;

return
entityKeyList;


}



private static void updateCustomer(AxdCustomer
customer)


{


CustomerServiceClient proxy = new CustomerServiceClient();


CallContext context = new CallContext();


context.Company = "ceu";




foreach (AxdEntity_CustTable
custTable in customer.CustTable)


{




custTable._DocumentHash = custTable._DocumentHash;


custTable.RecId = custTable.RecId;


custTable.RecVersion = custTable.RecVersion;


custTable.action = AxdEnum_AxdEntityAction.update;


custTable.actionSpecified = true;

custTable.CreditMax =
custTable.CreditMax + 10;


custTable.CreditMaxSpecified = true;



#region Update the date effective
entities


AxdEntity_DirParty_DirOrganization
dirPartyTable = (AxdEntity_DirParty_DirOrganization)custTable.DirParty[0];


dirPartyTable.action = AxdEnum_AxdEntityAction.update;


dirPartyTable.actionSpecified = true;




AxdEntity_OrganizationName orgName =
dirPartyTable.OrganizationName[0];


orgName.action = AxdEnum_AxdEntityAction.update;


orgName.actionSpecified = true;


orgName.updateMode = AxdEnum_ValidTimeStateUpdate.Correction;


orgName.updateModeSpecified = true;
