Говорим про заявки на покупку - так?
Класс PurchReqWorkflow.

Метод 1:

void submit()
{
    Object                      purchReqTable_ds;
    NoYes                       activatingFromWeb;
    boolean                     canSubmit;
    ;

    canSubmit = PurchReqWorkflow::canSubmit(purchReqTable);

    if(canSubmit)
    {...

И собственно сама проверка на возможность запуска:

public static boolean canSubmit(PurchReqTable purchReqTable)
{
    PurchReqLine        purchReqLine;
    boolean             canSubmit           = true;
    PurchReqParameters  purchReqParameters  = PurchReqParameters::find();
    VendTable           vendtable;
    ;

    purchReqTable.reread();

    if (purchReqParameters.HeaderBusinessJustification)
    {
        if (PurchReqBusJustification::find(purchReqTable.TableId, purchReqTable.RecId).BusinessJustification == '')
        {
            canSubmit = checkFailed("@SYS110605");
        }
    }

    if(!(purchReqTable.State == PurchReqWorkflowState::NotSubmitted ||
            purchReqTable.State == PurchReqWorkflowState::Returned ||
            purchReqTable.State == PurchReqWorkflowState::ChangeRequest))
    {
        throw error("@SYP4572");
    }
