chain of command in d 365

create a class 

[ExtensionOf(classStr(SalesLineType))]

final class SalesLineType_Extension

{

    

    

    public void inserting()

    {

       

        CustTable   custTable;

        

        //get customer for evalation of credit rating

        custTable = CustTable::find(salesLine.CustAccount);

 

        if(!custTable.CreditRating)

        {

            info("Customer on sales line has no credit rating!");

        }

 

        // must call next when using Chain of Command pattern

        next inserting();

       

    }

}

first 2 lines are important as it tells it is an extension of which class and suffix should end with _extension

now add sales table form in the project and add as a start up object  and run  the visual studio and once browser is open navigate to new button and create a  new sales order  and save  then the message will pop up  in the screen , you can debug the process also .

by loading the symbols it will take some time to load all the symbols.
