Create First Custom Service In Microsoft Dynamics AX 2012

There is very good blog available for creating the Custom Services in Microsoft Dynamics 2012.

http://sumitsaxfactor.wordpress.com/2012/05/19/create-your-first-custom-service-ax-2012/


One thing I just wanted to mention here that is not given in this blog is:

While consuming your newly created service outside AX in your C# or any other code you need to specify the company name in which your x++ service code will execute.

if just pass the code as mention in above blog post i.e

string[] custIds = servClient.retrieveCustomerNames(new SamCustomAXService.CallContext(), strItem);  

than your code will run in dat company which by default set in AX and it contains no data therefore it will not return any data which you want.

To run your x++ service code in your specified company than you have to create the object of call context and in that object specify your company. You can see the below code for reference.

In my case I have specified the ceu company.

 mzkCustomerService.CallContext context = new mzkCustomerService.CallContext { Company = "ceu" }; 

and than pass this context object in your code as below:

string[] custIds = servClient.retrieveCustomerNames(context, strItem);  
 

This was all related to the Custom Services.

Remove Dynalinks Between Forms in Microsoft Dynamics AX 2012

Some times when we open the child form from another form than the datasource of the child form is sync with the previous form this is due to the dynalink between these two forms and all the data is shown on the child form.

you can use the below code on the init method of the child form after the super() to remove the dynalink between these two forms.

DataArea_DS.query().dataSourceTable(tableNum(DataArea)).clearDynalinks();
UserDataReaFilter_DS.query().dataSourceTable(tableNum(UserDataAreaFilter)).clearDynalinks();

The above two datasources are the datasources of the child form.

For info related to the dynalink you refer to the below link.

Convert Currency based on the Exchange Rates in Microsoft Dynamics AX 2012

In Microsoft Dynamics there is a method available for converting the amount from one currency to another based on the exchange rates.

The method that I am talking about is curPrice2CurPrice method in Currency table.

Below is the code of this method

You have to pass the price and the old currency in which the price actually is and the new currency in which you are converting the price.

Same method is implemented on Purchase Order Form.You can see the existing behavior if you have R2 installed.Just create new purchase order and than create some purchase order lines in it and than in the purchase order header tab change the currency.

After changing the currency the unit price in the purchase order line will convert based on the currency that you have selected.

You can see the below images before and after changing the currency on purchase order.

 Before changing the currency:

  
After changing the currency:

You can also see the exchange rates on the below navigation path:

GL --> Setup --> Exchange rate type --> Set Default --> check currency for which you need to check the exchange rate for

This was related to the currency and exchange rates.
I hope you like it :)
