2. Type the IF nodedescription in the Descriptionfield.

3. In the Codefield, write the logical condition that the IF nodeshould be tested for. The condition must be stated in the form of an X++ expression. For a description of X++ expressions, see the Microsoft Dynamics AX Developer's Guide.

4. Click Testto test the code syntax.

5. Click OKto save the code and close the IF - conditionform. The IF nodewill be created that has two subnodes:

   • THEN node
