Use this dialog box to perform project material requirements planning (project MRP), by considering one activity at a time, when calculating net requirements. This means that excess supply of a part from other activities which are under consideration in the same process, will not be used to meet shortages in the current activity, and excess supply belonging to the current activity will not be used to satisfy shortages in other activities. project MRP can be performed for all the parts required for a specific open project or all open projects, at a single site or at all user-allowed sites. If you click Schedule, it will open a window to create a new schedule. Specify scheduling parameters until it is completed. Once it is done, the scheduled job can be queried from the Scheduled Database Tasks window. When you initiate the process, a project MRP background job is executed. You can view it in the Background Jobs window.
