The objective of MRP is to ensure material availability for the requirements. Requirements could be of two types — internal requirements and external requirements. External requirements originate from customer requirements which are entered into SAP as a sales order for example. Internal requirements are to manufacture components on the same plant which could be supplied as components to finished goods or to satisfy the customer requirements.
Advertisement SAP MRP checks the stock level of the respective material and generates procurement proposals or planned orders which could be either converted to purchase requisitions or production orders based on the MRP settings in material master records.
Material master has several views related to MRP viz. MRP 1 view has fields like purchasing group, plant special material status, MRP procedure, and lot size data. In material master MRP 2 view, fields like procurement type, special procurement, scheduling margin key, and planned delivery time are located. There is a separate tab available for net requirements calculation which includes safety stock, minimum safety stock which helps to calculate the required quantity at the right time.
Advertisement Also, Availability check filed is available which is used to maintain the checking rule for checking the material availability and update it for available to promise dates and quantities.
There is a separate tab available for Repetitive Manufacturing which helps to maintain REM profile that is used to enter and record transactions for repetitive manufacturing. If a material is subject is to in-house production, then work scheduling view would need to be maintained. If a material is subject to MRP planning, then all the four views of MRP would need to be maintained in material master.
SAP MRP process flow starts with customer requirement, which originates from the sales department or marketing department. The customer requirements are entered in SAP via sales orders.
The customer requirements are entered as demand in demand management system. The output of demand management is Planned Independent Requirements which would be used in long-term planning.
Now, materials requirement planning comes into picture. The input to MRP is from sales order and planned independent requirement, if applicable. When the MRP run is carried out, planned order or purchase requisition would be generated based on the planning run settings. Planned order could be converted into purchase requisition PR or Production order. Purchase requisition is for external procurement and production order is for in-house production. SAP will then convert all the dependent requirements of planned order into reservations in the production order.
When planned order is created for external procurement, it would need to be reviewed by planners, and if required planners would convert the planned order to purchase requisition. Otherwise, the purchase requisition would be generated automatically and available for purchasing.
In SAP MRP process, the system calculates the net requirements while considering available warehouse stock and scheduled receipts from purchasing and production.
During MRP process all levels of the bill of material are planned. This planning run can be executed for a single material or a material group. Planning run can be total planning for a plant, single-item single level planning, or multi-level single item planning. The SAP system creates procurement proposals which could be planned orders, purchase requisitions, schedule lines based on the planning run settings.
Planning file entry contains details of the materials that are to be included for the MRP run. There are three types of processing key:.
The figure above shows planning run at material level. The material and a respective plant are entered. Advertisement There are several fields which come under MRP control parameters control data. With this transaction code, we would be able to carry out planning run at a plant level. As this would consume a lot of time for the output to be displayed, it could be executed as a background job. MD02 — This transaction code is used to execute a planning run for a material and used to explode multi-level materials.
Enter the material and plant; this would give you the current stock with requirements or receipts. Have any questions or comments? We would love to hear your feedback in the comments section below.
