As most people know, SAP MM is all about procurement and inventory management. But it is not obvious to most people as to importance of SAP MM on SAP projects. Let us highlight this aspect in this post.
Any company may be in business doing sells of materials or services. Each service or material may need to be defined in the SAP system if the company is implementing SAP. So SAP MM is always a component on any SAP project no matter what kind of business the company is into.
If the company is providing services to its customers then all kind of services offered by the company are defined and kept in the system as a master data. If the company is into trading of goods then all kinds of goods traded by the company is defined and kept into the SAP system. If the company is into manufacturing then all raw materials procured by the company, the intermediate materials manufactured as well as the finished materials manufactured by the company are defined and kept in the SAP system. If the company is only warehousing products and transferring them to some retailer then again materials need to be defined and kept in the system.
So you see, SAP MM is an integral part of any SAP project no matter what kind of business the customer is into.
