Reading a Multiline Object Reference from a
Container (BOR)
Prerequisites
The following prerequisites must be fulfilled to read an object reference of a classic object (BOR) 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.
This prerequisite is 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.
Containers passed using a function module interface always contain persistent object references. Before you read an object reference from a container and store it 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>
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
Procedure
...
1. Create a variable for the multiline object reference. Use the following command to do this:
DATA <ObjectList> TYPE SWC_OBJECT OCCURS 0.
2. Create a variable for an object reference. Use the following command to do this:
DATA <Object> TYPE SWC_OBJECT.
3. Read the multiline object reference from the container. Use the following command to do this:
SWC_GET_TABLE <Container> <ContainerElement> <ObjectList>.
4. To access the individual object references, read the individual object references from the multiline object reference in a loop. Use the following command to do this:
READ TABLE <ObjectList> <Index> <Object>.
You can read the object type and the key from the object reference. To do this, use the macros SWC_GET_OBJECT_TYPEand SWC_GET_OBJECT_KEY. For more information, see Macro Instructions for Accessing Objects, Attributes and Methods
