SysComputedColumn implementation to add Computed Column in Dynamics Ax 2012 View

The purpose of this blog is to explore the new feature in dynamics ax 2012 through which you can use the computed columns in Dynamics ax View, complete class SysComputedColumns is available in AOT with lots of method in it. You can add any more based on your requirement and use them in your View as i have explained below through example.

1)     Create a method on SysComputedColumn class similar to:

publicstatic clientserver str len(str _expression)
return ‘LEN(‘ + _expression +’)’;

2)     Create a new view or select any existing and select the normal fields you want to the view from its datasource.

3)     Create a method on the view similar to:

publicserver staticstr mainAccountLength()
tableName viewName =tablestr(AbcTest);       // name of your view
str mainAccountLength;

mainAccountLength = SysComputedColumn::len(
(MainAccount_1), fieldstr(MainAccount, name)));

//identifierStr(MainAccount_1) = name of the datasource in the view.

return mainAccountLength;
(I used \Data Dictionary\Views\ProjTransBudgetCube\Methods\projBudgetPayrollAllocation as a baseline)
The purpose here in this example is to use the computed column in Dynamics ax 2012 View.

4)     Rightclick on the view fields node and select new INT computed column

5)     Set the viewmethod = mainAccountLength (the method created above)
