fine that means the data is going from RDP to SSR report; it is working as it should be
the issue is in following line which is not getting record
partyTable = DirPartyTable::findRec(HcmWorker::findByPerson(m_tSalesQuotationTable.WorkerSalesTaker).Person);
you have to debug it and figure it out that why record is not coming
may be sales taker is not selected for quotation.
may be some other reason.
you have to debug it and fix it
