Data which describes a supply relationship is stored in the purchasing information record. A master record must be created for the vendor. If a master record has been created for the material, it is a stock material info record, otherwise it is an info record for a material group (non-stock material). Data from the info record is proposed when purchasing transactions are entered. Analyses such as the following can be created on the basis of purchasing info records : - which vendors offer a certain material? - which material does a certain vendor offer Sources of supply for a material in a plant are defined in the source list. The validity of source list entries can be limited to certain periods. The source list of material is composed of source list records, each of which identifies a possible source of supply for the material. If a source list requirement exists, the material cannot be procured from sources of supply other than those included in the source list. A source list requirement is activated for a plant. A source of supply for a material can be blocked in the source list. Conditions can be determined on different levels. The most commonly used levels on which price agreements are made are defined in the standard system. You can create additional levels if required. With the classification system, objects can be described using the characteristics and similar objects can be grouped together in classes according to criteria chosen by user. You can search for objects, e.g. a material master record, with certain characteristics. The classification system can be structured with or without hierarchy classes. An object can be assigned to more than one class. The maintenance of characteristics includes the maintenance of - basis data (e.g. description, status, entry rules)- permitted values- interface control for user entries for the characteristic value- classification data for the characteristic The maintenance of the classes includes the maint
