SAP Master Data for ABAP Programmer

At the core of ERP server system SAP will store master data and every ABAP programmer shall know about the basics of this master data.

The master data in the SAP system represents the characteristics of the business entities or the business objects used in the system, for example, material, customer, and vendor. These are stored in Material Master, Customer Master, and Vendor Master tables.

SAP also has organizational objects that represent the various organization entities. These entities have a defined business responsibility and are used to represent the company's structure in different forms, such as the purchasing organization, sales organization, and company code.

An organizational object and an SAP organizational object are bit different. Organizational objects are entities such as users, positions, and jobs. SAP organizational objects are company codes and sales organizations. They were named SAP organizational objects because of their relevance to the SAP system.

When master data is created in the system, we define views for each SAP organizational object, depending on the master data. For example, when you create a vendor, you create a separate view for each company code and purchasing organization that deals with the vendor,. A view holds information specific to the respective SAP organizational object.

Similarly, if you are creating a customer master, you have a separate view for each sales area, which consists of a sales organization, distribution channel, and division. For the material master, you have views that are based on plants, storage locations, sales organizations, and so on.

You cannot create a purchase order for a vendor that has not been defined for your purchasing organization. You cannot order a material for a plant if the material has not been created for that plant and all this shall be done at the system level during the process of SAP project initiation.
