Dear All,
I would like to request your guidelines for me. I would like to do a pop-up menu before calling a standard class on [Form: SalesTable] but I have 2 obstacles.
1. how do I call a standard function in my class?
2. how do I refer an id for my SQL to query a number of my tax types?
this is a step that I do:
1. I prepare sample data that I like to test
(Before pressing confirm sales order I want popup windows to tell users /please keep in mind that this sale Order had x type of Tax Invoice/)
2.I trackback and I found /Confirm sales order/ is a Button menu and for this menu call action menu /SalesFormLetter_Confirmation/
3. I extend class /SalesFormLetter_Confirmation/ and change object to call to /MOT_SalesOrderTaxAlert/
4. I dev my code for /MOT_SalesOrderTaxAlert/ and I try to call standard class /SalesFormLetter/ to process in a next step but I got an error message it is a /abstract/
5.Now output when I build/run it can show only this message but for the core objective I can't do please help.
Best regards,
Thanakorn.
