Reading an Object Reference from a Container

The following prerequisites must be fulfilled to read an object reference of a BOR object from a container:

• For function modules, the include file <CNTN01> must be incorporated in the program. For ABAP classes, the include files <CNTN02> and <CNTN03> must be incorporated. For more information, see Macro Instructions for Processing a Container .

  Note

  These prerequisites are always fulfilled if you are in the implementation program . The container is then addressed with the name CONTAINER .

• The object references of the container must not be persistent.

  Note

  Containers passed using a function module interface always contain persistent object references. Before you read object references from a container and store them in a variable, you must make all object references in the container into runtime references. To do this, execute the following macro instruction:

  SWC_CONTAINER_TO_RUNTIME <Container>.

  Example

  You must process a container with this macro if you:

  • Read a rule container for rule resolution

  • Read an event container within a check function module or a receiver type function module .

1. Create a variable for the object reference. Use the following command to do this:

   DATA <Object> TYPE SWC_OBJECT.

2. Read the object reference from the container. Use the following command to do this:

   SWC_GET_ELEMENT <Container> <Containerelement> <Object>.

You can read the object type and the key from the object reference. To do this, use the macros SWC_GET_OBJECT_TYPE and SWC_GET_OBJECT_KEY . For more information, see Macro Instructions for Accessing Objects, Attributes, and Methods .

DATA <Objekt>   TYPE SWC_OBJECT
     <Variable> LIKE SWOTOBJID.
SWC_GET_ELEMENT <Container> <Containerelement> <Variable>.
SWC_OBJECT_FROM_PERSISTENT <Variable> <Objekt>.
