Adding Lookup with custom range on Forms In Microsoft Dynamics Ax 2012

Its quit easy in Microsoft Dynamics AX 2012 to create the lookups.

Lookups are basically the drop down list through which we are selecting the value and then setting the value behind that field.

You can see in the below image on what lookups are and how they work.

  In the above image when we click the add button or click the purpose field then the lookup is open.You can make these kind of lookups in your own forms.

Below are the steps for making the custom lookup with your define ranges.

 Step 1:

First on the form -> DataSource right click the field on which you are making the lookup and than select the override method lookupRefrence().

As you can see in the below image.

Now you can see whats inside that method.

Actually in the above code I am calling the another method that I write on the table level.Inside that method I have make the logic of the lookup.

In the below image you can see the logic of that method for making the lookup.

Basically in that Method I have made the query which fetches the record based on our criteria and than we make lookup on the based on the fetched data and than return it to the form.From where it was called.

That was all from my side related to the custom lookups.

I have also see a very good link related to the lookups.You can also check this.
