Creating a custom service

A custom service in Dynamics AX allows any X++ logic to be exposed as a service. Custom services are normal X++ classes decorated with attributes, which allow any existing methods to be exposed as service operations without writing any additional code.

In this recipe, we will create a new custom service with a single, simple operation. The operation will accept currency code and return the currency description.

How to do it...

Carry out the following steps in order to complete this recipe:

1. 1. In the AOT, create a new class named CustomCurrencyService with the following code:

   class CustomCurrencyService
   {
   }
   [SysEntryPointAttribute]
   public CurrencyName getCurrencyName(CurrencyCode _currencyCode)
   {
   return Currency::find(_currencyCode).Txt;
   }
   

2. 2. Set the class properties as follows:

   Property	Value
   RunOn	Server

3. 3. In the AOT, create a new service with the following properties:

   Property	Value
   Name	CustomCurrencyService
   Class	CustomCurrencyService
