Run a class on a form, not current form

Hi Professionals,

I have a menuitem in FORM A which call a class correctly.

I have another FORM B and there is a menuItem to call the same class.

I wish to call and run the same class on Form A, not Form B.

How can I hard-code form A in my class or is that possible?

class PurchTotalsSummaryController

{

}

publicstaticvoid main(Args _args)

{

    PurchTotalsSummaryController my_PurchTotalsSummaryController = new PurchTotalsSummaryController();

    PurchTable purchTable;

    FormDataSource purchTable_ds;

    purchTable = _args.record();

    purchTable_ds = PurchTable.dataSource();

    my_PurchTotalsSummaryController.getRecId(purchTable_ds,_args);

}

privatevoid getRecId(FormDataSource purchTable_ds, Args _args)

{

    FormRun                 caller;

    MultiSelectionHelper    helper;

    PurchTable              purchTable;

    ;

    //The method createFromCaller from MultiSelectionHelper has FormRun as parameter so we need to assign Args.Caller() to FormRun

    caller  = _args.caller();

    //This method will help to get only the marked records from the Grid

    helper  = MultiSelectionHelper::createFromCaller(caller);

    //Create the Query to filter using RecId

    helper.createQueryRanges(purchTable_ds.queryBuildDataSource(), fieldStr(purchTable, RecId));

    //Obtains the first query result and then assign it to table buffer

    purchTable = helper.getFirst();

    //True if purchLineView contains RecId

    while (purchTable)

    {

      //Simple example to show all RecIds from selected grid rows

      info(StrFmt('%1, %2, %3', purchTable.RecId,purchTable.ProjId,PurchTable.OrderAccount));

      //Gets next record

      purchTable = helper.getNext();

    }

}
