Material Requirements Planning (SAP Library - Material Requirements Planning (PP-MRP))

Material Requirements Planning

Implementation Options

You use this process, if you are an MRP controller in a medium-sized company and are responsible for the whole of the material requirements planning process and material availability. After a normal MRP run, you check the stock/requirements situation for the planned materials, make necessary changes and save the availability of the materials for the next days.

Prerequisites

You have completed an MRP run.

You have configured the lists as you want (for example, a material tree, display of total replenishment lead-time).

See Configuring Access to the Lists

You have configured the material tree as you want (for example, the materials in the tree are to be grouped according to processing indicator).

See Select Fields in the Tree, Sort/Group Fields in the Tree

You have configured the traffic lights as you want (for example, all materials with dates in the past as well as all materials with terminations are to have a red traffic light).

See Define Traffic Lights

Process Flow

You choose collective access to the MRP lists (MD06) from the role-based menu for the MRP controller or from the personal favorites.

In the screen for collective access, you select your own materials according to MRP controller and plant and enter that you only want to see materials with new exceptions. The material list appears.

See Using Collective Access for MRP Lists

In the material list, find the materials that have priority for processing with red traffic lights.

See Searching for Information

You copy these materials to the worklist tree. At this point, all of your materials are in the group of materials with unprocessed MRP lists.

See Material Tree

You call up the corresponding MRP list by double-clicking on the material in the tree and check which exception messages for this material have occurred during the total replenishment lead-time.

You double-click on every critical MRP element to call up the dialog window with the details for the MRP element. From the dialog window, you access the screen for processing the MRP element and, if necessary, change the dates or quantities after consulting the workshop, customers or vendors. The system then automatically firms the MRP elements, which you have changed manually.

See Working with Individual MRP Elements

You check, if necessary, the result of the manual changes in the stock/requirements list. For critical quantity changes, you execute, if necessary, a new single-item planning run directly from the MRP list. You can use flexible transaction calls for this.

See Flexible Transaction Calls

If necessary, you convert individual planned orders into production orders and individual purchase requisitions and thereby trigger the production or procurement. (A collective transaction for the conversion of a larger number of MRP elements is available.)

See Working with Individual MRP Elements

Once you have completed the processing of a list, you set the processing indicator. The system automatically moves the material with the processed MRP list in the worklist tree to the group of materials with processed MRP lists.

See Working with Whole Lists

You continue processing the MRP lists until the system has moved all materials in the worklist tree to the group of materials with processed MRP lists.

Result

The stock/requirements situation for your materials is cleared again.
