What causes this issue?

An add-on or a customer-specific enhancement was not implemented
correctly in your system.
The <EX>CL_RECA_STORABLE_EXT=>MD_OBJNAME_EXT</> variable does not not
contain any values. Apparantly the <EX>INIT_BY_PARENT</> method was
redefined within a subclass of <EX>CL_RECA_STORABLE_EXT</>, without the
method of the super class being called.
The call of the method in the super class should be as follows:
CALL METHOD super->if_reca_storable_ext~init_by_parent
EXPORTING
id_objname_ext = id_objname_ext
io_parent = io_parent.

System Response

The program had to be terminated, because it is no longer possible to
correctly assign the enhanced objects to the standard objects, and if
processing continued, this could cause data inconsistencies.

How to fix this error?

Contact your system administrator.
The implementation of the enhancement (subclass of
<EX>CL_RECA_STORABLE_EXT</>) has to be corrected.

Procedure for System Administrators
