The statement INTERFACE-POOL introduces an interface pool. It must be the first statement of an independent program after resolving possible include programs.

Interface pools are edited only with the tool Class Builder in ABAP Workbench. A framework program for a global interface including the statement INTERFACE-POOL is generated automatically.

The full name of the framework program of an interface pool in the repository starts with the name of the global interface, is padded with the character "=" up to and including position 30, and ends with "IP".

The names of the include programs of an interface pool included by the framework program are constructed in exactly the same way as the name of the interface pool itself, however they have different endings. Unlike the case with function groups, the actual structure of an interface pool constructed from include programs is the internal responsibility of ABAP Workbench and the ABAP runtime environment and is not displayed in Class Builder.


The statements permitted in an interface pool are listed under Statements in Class Pools and Interface Pools.


The name of the framework program of the interface pool of the global interface IF_DEMO_CR_CAR_RENTL_SERVICE is IF_DEMO_CR_CAR_RENTL_SERVICE==IP.
