hello everyone i'm trying to controle a button that i added in SalesEditLine.

if i open SalesEditLine from the pro forma invoice button in sales orders, i want it to be disabled.

if i opened it from the Sales Update button in SalesPostingHistory i want it to be disabled.

to do so i tried to use args.caller() but the caller is SalesFormLetter in both cases so it didn't work.

i tried to pass a parameter in the clicked method of the button so i can use it in the init method of SalesEditLine form this is the code.

[Control(/Button/)]    class ButtonUpdate    {        void clicked()        {            Args    args;            super();            str test = 'test';            args = new Args();            args.record(salesParmTable);            args.parmEnum(enum2int(DocumentStatus::Invoice));                        args.name(formstr(SalesEditLines));                        args.parm(test);            SalesFormLetter::main(args);                        salesParmTable_ds.active();        }    }

but i get this error.

any solution to this error or any other solution for the problem.

Isn't the difference in that SalesPostingHistory from creates a SalesFormLetter object for an existing SalesParmTable record?

Hard-coding DocumentStatus::Invoice in SalesPostingHistory is a bad idea, because this form is used for other posting types as well.

OK, let me show you how to get the answer.

When you look at what ButtonUpdate in SalesPostingHistory does, you'll see this code:

args = new Args(); args.record(salesParmTable); args.parmEnum(enum2int(documentStatus)); SalesFormLetter::main(args);

If you want to know what happens inside main(), simply go to the definition. You'll find that args.record() is set to a local variable called record, which is then passed to SalesFormLetter::constructAndInitialize(). That calls initializeFromCallerRecord(), where you're interested in the section initializing the object from SalesParmTable. Remember, that's the table I pointed out to in my previous reply. There you'll see this call: this.parmCreateFromHistory(true).

That's you answer. You can use parmCreateFromHistory() method of SalesFormLetter class to determine whether the call was made from posting history.
