Read Plug-In

A read plug-in is a group of read modules and is primarily used as a structuring aid when many tables are involved.

A read plug-in can be used by multiple archiving and deletion objects (reuse, read plug-in sharing, central definition of read modules and reuse in multiple archiving scenarios). This should usually be avoided.

One read plug-in is preferable for lightweight scenarios. It can have the same name as the scenario itself (standard naming convention).

A read plug-in is therefore a grouping term for read modules. A read plug-in is used to structure the retrieve method for a business object.

A read plug-in can be reused by multiple scenarios. In this case, a read plug-in replicates the functions of a class.

Check whether the read plug-in is a better option for shared data than the usual classes:

- Read plug-ins enable the business display of archived data (business view). Classes do not.

- Archiving scenarios with archiving classes cannot function as pure deletion objects. Archiving objects with read plug-ins can also be used as pure deletion objects in principle.

- Archiving scenarios with read plug-ins are optimized for performance. Archiving scenarios with archiving classes are in many cases suboptimal with regard to performance.

- Unlike archiving classes, a read plug-in enables flexible enhancement (additional tables to be included).
