Functionality
This function module checks out a set of object types (classes orinterfaces) in LOCK mode. This means:
The full object types are read. A full object type consists of basicinformation, components (attributes, methods, events), subcomponents(parameters, exceptions) and outgoing relationships (is friends with,inherits from, contains, references).
The system checks the user's authorization when reading (not yetimplemented).
The object types read are included in a correction or repair request.They are therefore locked, and cannot be changed by other users.
The following criteria must be met in order for the check out to work:
There must be a valid correction or repair request. If necessary, youcan generate one using the function moduleRPY_CICO_REQUEST_OPEN.
None of the objects that you want to read may be locked by anothercorrection or repair request.
If the conditions are not met, or another error occurs during checkout, the check out does not take place and no object type data isreturned by the function module. The relevant error messages are placedin the error table ERROR_SET.
In the import parameter CICO_REQUEST_NO, enter the number of thecorrection or repair request.
In the table parameter CLASS_INTERFACE_IDS, enter the names of theobject types for which you want to read information.
By default, all long texts are reaed in the system language. If youwant to read texts in a different language, enter its ID in the importparameter LANGUAGE.
The information about the object types read by the system is passedback to the caller in the relevant tables parameters (for example,events in the table EVENT_SET).
The funciton module does not trigger any exceptions. Problem and errormessages are returned to the user in the error tableERROR_SET. If the entire check out is successful, theerror table is empty.
You can release the correction or repair request using the functionmodule RPY_CICO_REQUEST_CLOSE. Thisreleases the lock on the object types that have been read.

Example
The following call checks out the object types 'EXAMPLE001' to'EXAMPLE003':
