This module has several features and functionalities that are fully integrated with the other important modules like Finance and Control, Sales and Distribution, Production Planning etc. The procurement process consists of a chain of events that take place in order. Starting from the creation of a Purchase Requisition (PR), it moves to the authorization of PR and creation of a Purchase Order (PO). Subsequently, the Goods Receipt is generated on receipt of the goods ordered, Invoice Verification takes place and the Quality Control activities are set in motion. Thereafter, the payment is sent to the vendors for their goods /services.

Benefits of SAP MM
With customer demands changing rapidly, an organization’s efficiency is measured primarily by its ability to cater to the market demands in the shortest time possible. For this to happen, the business has to have stock of the required raw materials at the right time and must be able to use it efficiently. A proper Material Management process ensures that there is never a shortage of materials or any gaps in the supply chain process of the organization. The SAP MM automates the procurement and material management activities to make the processes smoother and effective. Some prominent benefits of SAP MM are:
- Reduces material costs by avoiding stocking of unnecessary or obsolete materials
- Inventory losses are minimized
- Direct labour costs are reduced and labour can be used efficiently
- Manufacturing cycle times are reduced and can be controlled effectively
- Effective inventory management and reduces expenditure on unwanted material storage
- Improves delivery time and increases transparency across the organization
Challenges for Implementation
While the benefits of SAP MM outweigh the challenges faced in its implementation, organizations must be prepared to dedicate their time and ensure that these challenges are overcome:
- Information on the material requirements, planning activities and order inputs must be managed carefully and should be reflected correctly for the module to be accurate
- Proper forecasting methods should be followed so that materials planning and demand forecast is in line with the manufacturing requirements
- Quality control methods should be integrated properly to ensure that the product quality is maintained up to standards
- Vendors must be selected carefully to suit your quality management principles. This not only safeguards the end-product quality but also the reputation of your company

- What is MRP? And how is Lot Size used?

It is basically used to determine your Material Planning procedure by specifying the various conditions like Reorder Point, Seasonal Requirement, Replenishment, Vendor Managed, Forecast Based and Master Production Scheduling (MPS). Lot size specifies the nature of material requirement in terms of Weekly, Monthly, Quantity and Maximum Replenishment.

- What are batches and how are they searched?
A batch is a collection of similar items from your stock that have the same characteristics. For example, all food items produced on a particular day belong to one batch.
Batches are searched using the standard facility (match code, key F4) based on the batch names or other properties that distinguish them from others.
- How is shelf-life managed in SAP? Explain the full-cycle.
In SAP, there are basically two types of shelf-life:
1. Total Shelf Life – In case the total shelf life is maintained, then it’s mandatory to enter the minimum shelf life also. During the process of Goods Receipt (GR), the user will have to enter the manufactured date of the item so that the expiry date is automatically calculated by the system.
2. Minimum Shelf Life – The date of minimum durability of the item are specified by using date markings like ‘use-by’ or ‘best-before’. During the process of Goods Receipt (GR), the user will have to enter the date of GR so that the system can check if the material is usable according to the requirements in material master. If the minimum remaining shelf life condition is not satisfied, then the system will not accept the goods receipt.
- What is a release strategy? What are release groups and codes?
The procurement process in SAP needs to be controlled by introducing authorizations at important stages. This is taken care by the release strategy, which has different codes for assigned users. For example, if the value of a PO is more than a certain pre-defined limit, then it has to be approved by the SCM manager with a certain release code. Every company will have different approval mechanisms and the release strategy can be defined by the users.
Release groups are a set of release codes that are used for authorizing a purchasing document or approving a release strategy. Release code is a 2-character ID that allows a person to approve or clear a PR or a PO and they are controlled by a step-by-step authorization system. For example, Code 10 is assigned to the person who creates the PO, Code 20 is the release code assigned to the Purchase manager for approval. Subsequently, the Department Head will use Code 30 to approve the release strategy, followed by the Operations Director, who will use Code 40 for final approval.
- What is a GR blocked stock and when is it used?
The GR blocked stock is an option used in the goods receipt process when you are not sure about the quality of the goods received. In such a case, the stock is maintained as GR blocked either from a material viewpoint or exclusively for a purchase order item.
