When the task is completed, the internal order status must be changed to TECO/CLSD. Before processing this activity, the responsible person must be rest assured that all the pending tasks for the specific are completed. This is because changing the status of Internal Order to CLSD will prohibit all the actual transaction. The PR/PO cannot be issue against the targeted internal order. Thus, this process is normally committed when all tasks for the particular job is done. Otherwise, the status of the internal order will be set to “TECO” in order to prevent the issuing of new PR/PO and to allow accounting process to be continued.
