Definition

If the generated function modules for access plan calculation or data selection make use of the option to read all child table records for a set of header table records with the FOR ALL ENTRIES selection, it might improve the performance to add a DB optimizer hint for the MAX_INT_BLOCKING_FACTOR. By default, the value is only 5, which means that only 5 child table records are selected in one DB operation. It is sometimes advisable to increase this number.

For details on the MAX_IN_BLOCKING_FACTOR DB hint, see SAP note 881083 (what is described there for Oracle also applies to other DB systems).

For details on the FOR ALL ENTRIES selection option, see DMC_FOR_ALL_ENTRIES
