Solution: add the Supplementary Items functionality to Project Item Requirements

1. Add a new MenuItemButton to the MenuButton control ButtonLinePriceCalc on the ProjSalesItemReq form.
2. Set following properties on the newly added control:
   MenuItemType: Action
   MenuItemName: SuppItemCalc_Sales
   DataSource: SalesTable
3. Override the clicked method of the newly added control and add following code:
   

   void clicked()
   
   {   
       Args        _args = new Args();   
       ;
   
   
       _args.record(SalesTable::find(salesLine.SalesId));    
       SuppItemCreate::main(_args); 
     
       salesLine_ds.reread();
   
       salesLine_ds.refresh();
   
       salesLine_ds.executeQuery();
   
   }

   
   

Do the necessary setup of a trade agreement of the supplementary items kind for a specific item. Add an item requirement for that item. Execute the Calculation of Supplementary Items: you’ll see the results according to your created trade agreement.

Solution: Rename the added Style

I described in a previous post Export to Excel with X++ code: the sequel, how formatting can be added to the exported AX data in Excel by using the Styles class. This error message occurs when the collection object of the same class and name already exists, and you attempt to add it a second time with the same name. So apparently I had already a Style in my Microsoft Excel file with the same name as I was adding through my X++ code. I changed the name of my added Styles in my X++ code an my export went fine afterwards.
