One thing please provide your response. Due to our actual service deliverable which is computer software program code and it has to go through the requirement(functional spec) confirmation first then do the programming development afterward. Therefore, it might be Y/N of the CR(change request;already confirmed requirement that change to others by customer request) happening under service progressing duration. If yes then it will need the CR service fees add-on and how did Ching Luh process it if using the one time charge type software license product instead of could be several times type software program development? Can it issue several times software product PO with same object/subject related CRs such as TONI002, TONI003... after TONI001? Thanks
