Object Instance Enhancements

Object Instance Enhancements are loaded per object instance. The enhancement spot /PCH/BO supports filter to restrict an implementation to an object type. To enhance a specific object type the enhancement spot /PCH/BO must be implemented. Most of the business objects supports additional enhancement options. They can be implemented by adding a object specific OO interface to the implementation class.

Enhancement Spot BAdI Interface Method	Description
/PCH/BO (Business Object)
/PCH/BO	Enhancements for business objects
INIT	At Initialization of a new business object. A business object is created once per object instance. Use this method to save a local reference to the corresponding business object instance. The business object is not passed to the other methods.
FREE	When the business object is finally cleaned up. Use this method to release you local data.
MAP	Most of the business object are reading only a subset of the main data from the database to increase performance. Additional fields can be added by simply enhancing the corresponding data structures (see Business Object Data Enhancements ). The data between several data structures are mapped automatically. In some cases you might map data by yourself.
GET_FIELDS_METADATA	Retrieving fields meta data. Screen modes (hidden, readonly, ...) can be change, but no definitions must be created or deleted.
GET_METADATA_ CATALOG	Retrieving global meta data catalog for business object parts (e.g. basic data, classification,...). Screen modes can be change, but no catalogue entries must be created or deleted.
BEFORE_START_ CHANGE	Before starting change. This can be either a normal change, deleting or creating. Start of change can be interrupted by own checks.
AFTER_START_ CHANGE	After change has been started. Change token is passed to set custom data using business object methods.
BEFORE_SAVE	Called immediately before saving data. Change token is passed to set custom data using business object methods. Validation must not be done here (see VALIDATE).
AFTER_SAVE	Called after save was performed. Commit mode is passed to find out if booking was synchronously.
AFTER_CANCEL	After a started action was cancelled.
VALIDATE	Validation of all data. Errors can be returned.
BEFORE_INVALIDATION	Before invalidation takes place the control table can be adjusted.
IS_CHANGEABLE	Further checks, if an object can be changed. If changes are not allowed by business object this can not be overridden.
IS_DELETABLE	Further checks, if an object can be deleted. If changes are not allowed by business object this can not be overridden.
CHECK_ AUTHORITY	Additional authority checks.

Enhancement Interfaces
Most of the business objects provides additional enhancement options which can be activated by adding one of the following interfaces:
