Authorization checks and field selection is performed in material master according to the maintenance status. This page has been created to explain the role of maintenance status briefly.
Besides the organisational level, also another aspect is important for storing material master datas. This is the question: for whom are the respective datas relevant? Someone from the sales department will not be interested in work scheduling datas, and an MRP controller should not be able to change quality management datas. To manage such requirements, the ERP system uses so-called 'maintenance status'. Every maintenance status is represented by one letter, which is referring to one user department. The predefined maintenance status are:
Material Requirements Planning (MRP)
Storage location stocks
On the one hand, these status are used in the material master database tables to mark whether datas from the respective user department are maintained.
This is done in database tables:
General Material Data
Plant Data for Material
Storage Location Data for Material
MRP Area for Material
On the other hand, these status are also used in customizing.
