Mass Maintenance It is frequently necessary to revise a large volume of master data using a mass-maintenance function. What is primarily involved here is master data that (a) cannot be transferred (or cannot be transferred completely) from external systems and (b) exists in large quantities. Since selections of several thousand entries are not uncommon in the case of certain master data, a special mass maintenance tool is essential to minimize the amount of time required to process such data.
Mass maintenance involves the mass changing of individual attributes of master data, the creation of new data records, the assignment of existing objects, and mass deletion.
A tool is available for the mass maintenance of master data. This tool can be used in all projects having large volumes of such data. This tool facilitates the efficient changing and supplementation of master data.
You can use the mass maintenance tool to process the following master data:
External procurement relationships
Sales scheduling agreements
Locations
Production process models (PPMs) (SAP APO only)
Products
Quota arrangements
Resources
Transportation lanes
You can only make simultaneous mass changes for one of the above types of master data in each case. It is not possible to make mass changes for several types at the same time.
Caution
The mass maintenance tool enables you to change a large number of objects simultaneously. The changes directly impact all selected objects. This tool should therefore only be used by experienced users exercising due care.
