Perform Project Master Schedule Calculation

Explanation

This activity is used to perform project master scheduling (project MS) for either a single part, or for all the parts belonging to a specific site and project planned netting group (PNG). This process uses information from the forecasted demand that you have entered and the actual backlog of orders. It calculates forecasted demand and actual orders, traces orders, and provides action messages. When initiating a project MS process for a site or PNG you may set it up so that project material requirements planning (PMRP) and material requirements planning (MRP) are run immediately after project MS.

Prerequisites

This activity requires that:

• A project MS part needs to be defined.
• Forecasted demands need to be registered.

System Effects

As a result of this activity:

• If you perform project MS for a site or PNG, one or more background jobs will be executed to perform project MS and, optionally, PMRP and/or MRP.
• The project MS process generates proposals as required. Shop order requisitions and purchase requisitions may also be created for fixed proposals, if you have indicated that requisitions need to be created. During the process, existing proposals and requisitions in Planned state for the part are removed and new ones will be created if necessary. These proposals are created for the forecast activities.
• Material transfer requisitions may also be created to transfer material between activities.
• Action messages may be displayed in the Project MS Part/Action Messages tab.
• The gross demand per activity is made available and this forms the basis for the MRP calculation.
• The projected quantity of the part on-hand is analyzed and displayed in the Projected Balance field in the Project MS Part/Register Forecast tab. The physical quantity on-hand is also updated. This value is used to calculate the development of quantity on-hand and the quantity available to promise.

Procedure

To perform project MS for a single part:

1. Open the Project MS Part window and query for the desired project MS part.
2. Right-click anywhere in the header and then click Run Project MS. The Calculate Project Master Scheduling for a Single Part dialog box appears.
3. Change the value in the Run Date field if necessary and then click OK.

To perform project MS for a site or PNG:

1. Open the Calculate Project MS dialog box.
2. In the Site field, enter the short code of the site for which you want to perform project MS, or select it from the List of Values. If you enter % here project MS will consider all your sites during the calculation.
3. In the PNG field, enter the ID of the desired PNG. If you enter % here project MS will consider all the PNGs that exist in the selected site(s).
4. In the Run Date field, enter the date when you want to perform the calculation.
5. Select the Stop Project MS on Error check box if you want the project MS process to stop when errors are encountered.
6. Select the Start PMRP once Project MS is completed check box if you want PMRP to be performed after project MS.
7. Select the Start MRP once Project MS is completed check box if you want MRP to be performed after project MS.
8. Click OK.
