Display method D365 FO

Let us try adding a display method to a form where a new has been added to the Extension form . Since this is an extension form, a new display method cannot be added directly to this form or table.  In D365 FO, there is a slight difference in creating this . So, whenever there is an extension in D365 FO, in order to implement a process, we create a class first. So as a first step here, we are creating a class , but we use “Final” keyword .

We need to mention for which object this class has been created. So decorate the class with “ExtensionOf” attribute. In this discussion, I am creating a display method for the table “SalesQuotationLine”.

 Add the attribute to cache the display method.// only for Display method.

[ExtensionOf(tableStr(SalesQuotationLine))]

final public class AE_SalesQuotationLineTbl_Extension

{

[SysClientCacheDataMethodAttribute(true)]

public static display Qty fulfillmentRemainingQty(SalesQuotationLine _this)

{

//logic

}

How do we refer this method in the form?

Please note the property “Cache data method” is set to Yes when the display method is referred.
