Functionality

The class provides checks for modelling MDF object types.

The current status of a stored object type, object types that have not yet been stored, and changes to existing object types can be checked against the current data in the database.

The current data in the database is buffered. If changes are made to the database during the checks, the buffer must be reset for the relevant object type with method CL_DML_CUST_ACCESS=>INIT_BUFFER.

The checks include real error situations, but also report critical or meaningless constellations.

Relationships

Example

Notes

Removing text types, set types, or relationship types results in warnings. Note that the framework willcontinue to work without problems, but existing data for the removed text types, set types and relationshiptypes remain in the database. On the one hand, this inconsistent data occupies storage, and on theother hand existing objects would suddenly contain data for the new element if the removed text type, set type or relationship type were to be included again at a later time.
