Object Services classes work exclusively with
Class-Based Exceptions. The exception classes are predefined in the system. They always start with CX_OS_.
The Exception Class Hierarchy
Exceptions of the CX_DYNAMIC_CHECK category are passed to the caller using the RAISING clauses of interface methods; class-specific methods of the class actor; attribute access methods of persistent classes; in the transaction object; and the system actors. Such exceptions must be handled here by the user, (in contrast to the general rule that exceptions should be handled within a procedure, not passed along the hierarchy). Thus semantically, the above exceptions of the CX_DYNAMIC_CHECK category belong more to the CX_STATIC_CHECK category. However, they could not be defined as such, due to their incompatibility with existing Object Services applications.
In CX_NO_CHECK‘s subclasses, C
X_OS_NO_CHECK_CONTAINER and CX_OS_MIGRATION are noteworthy, since they are not part of the actual hierarchy for the Object Services exception classes. Their purpose is more internal: CX_OS_NO_CHECK_CONTAINER allows containers to pass along exceptions of the CX_DYNAMIC_CHECK category, while CX_OS_MIGRATION is used for migration purposes.
Description of Exception Classes
The following section lists the different variants of each exception class by TEXTID.
CX_OS_ERROR
This class is the root class of the Object Services exceptions of the
dynamic check category. Its immediate superclass is CX_DYNAMIC_CHECK.Text:
An exception has occurred in the Object Services Framework.
Note:
This exception class is an abstract superclass; it will never be raised.
CX_OS_OBJECT
Text:
An exception occurred while the object was being edited.
Parameter:
OBJECT type ref to OBJECT
Note:
This exception class is an abstract superclass; it will never be raised. There is a separate subclass for each class actor method (GET/CREATE/DELETE/REFRESH/RELEASE), which is handled instead. The TEXTID describes the error in more detail.

CX_OS_SYSTEM_ERROR
This class is the root class of the Object Services exceptions of the
no check. Its immediate superclass is CX_NO_CHECK.Text:
An exception has occurred in the Object Services Framework.
Note:
This exception class is an abstract superclass; it will never be raised.
CX_OS_SYSTEM
A system error has occurred.
Text:
An error occurred in the system actor of the Object Services.
COMPATIBILITY_MODE_ONLY
Text:
Transactions must be in compatibility mode when updating.
Raised (internally) by:
INIT_AND_SET_MODES( i_external_commit, i_update_mode )
RUNTIME_CHECK_ERROR
Text:
Inconsistency between mapping and database.
Raised by:
REGISTER_CLASS_AGENT
Note:
This exception occurs if the system discovers at runtime that the mapped table(s) contain(s) more columns than at the time the class actors were generated.
SYSTEM_NOT_INITIAL
Text:
The Object Services have already been initialized.
Raised (internally) by:
INIT_AND_SET_MODES( i_external_commit, i_update_mode )
CX_OS_DUPLICATE_OBJECT
The object with this key is already available. The object was not loaded when the system created a representative object for a reference, so that only the OID is known, not the business key. This means that there may be a second object with the same business key and another OID. Example: The system created an object (
o1) with a business key (in the roll area). However, another object (o2) has a reference (not yet loaded) to an object (o3) with the same business key. The OIDs are not identical, but there are two instances with the same business key.Text:
The object has been duplicated.
Parameter:
OID type OS_GUID
BKEY type STRING
OBJECT_BY_BKEY type ref to IF_OS_STATE
OBJECT_BY_OID type ref to IF_OS_STATE
Raised by:
IF_OS_FACTORY~DELETE_PERSISTENT( ref )
Attribute access during lazy loading from the database.
Note:
This error can only occur if you use mixed mapping (by business key and instance GUID combined).
CX_OS_INCONSISTENT_OBJECT
The object is inconsistent. The internal key data (business key and OID) do not match those in the database. For example, a program creates an object in memory. The business key for this object is already stored in the database. The object is then deleted, and then read from the database. The OIDs in this case would differ, which means that the object is inconsistent.
Text:
Inconsistent object
Parameter:
DB_OID type OS_GUID
DB_BKEY type STRING
MEM_OID type OS_GUID
MEM_BKEY type STRING
TABLE type TABNAME
Raised by:
Attribute access during lazy loading from the database.
Note:
This error can only occur if you use mixed mapping (by business key and instance GUID combined).
CX_OS_OBJECT_STATE
This exception is raised if an inconsistent state of a managed object occurs in the runtime system For example, an object is created (transiently or persistently) using a business key. The object is then loaded from the database using its OID.
