Additional additions for the statement COMMUNICATION.
Addition 1
... RETURNCODE rc
Effect
This addition can be specified for any communication steps and receives the return code in rc.
rc expects the data type i. The meaning of the return codes is encoded in the
include program RSCPICDF. Here, data objects with descriptive names and
start values are declared
and can be compared with rc. The following table contains a list of possible return codes.
| rc | Data Object from RSCPICDF |
|---|---|
| 0 | CM_OK |
| 1 | CM_ALLOCATE_FAILURE_NO_RETRY |
| 2 | CM_ALLOCATE_FAILURE_RETRY |
| 3 | CM_CONVERSATION_TYPE_MISMATCH |
| 6 | CM_SECURITY_NOT_VALID |
| 8 | CM_SYNC_LVL_NOT_SUPPORTED_PGM |
| 9 | CM_TPN_NOT_RECOGNIZED |
| 10 | CM_TP_NOT_AVAILABLE_NO_RETRY |
| 11 | CM_TP_NOT_AVAILABLE_RETRY |
| 12 | CM_DEALLOCATED_ABEND |
| 13 | CM_DEALLOCATED_NORMAL |
| 14 | CM_PARAMETER_ERROR |
| 15 | CM_PRODUCT_SPECIFIC_ERROR |
| 16 | CM_PROGRAM_ERROR_NO_TRUNC |
| 18 | CM_PROGRAM_ERROR_NO_TRUNC |
| 19 | CM_PROGRAM_ERROR_TRUNC |
| 26 | CM_RESOURCE_FAILURE_NO_RETRY |
| 27 | CM_RESOURCE_FAILURE_RETRY |
| 28 | CM_UNSUCCESSFUL |
The same return codes are also written to the system field sy-subrc.
Addition 2
... LENGTH leng
Effect
This addition can only be specified in the communication steps SEND and
RECEIVE. As a result, the data buffer buffer is only sent or received
in the length leng. The length leng expects a data object of the data type i.
Addition 3
... RECEIVED rec
Effect
This addition can only be specified for the communication step RECEIVE. The
data object rec contains the number of bytes received by the partner program. Only byte-like data objects of length 4 are allowed for rec.
Addition 4
... HOLD
Effect
This addition can only be specified for the communication step RECEIVE. It prevents the
internal session being changed when receiving data to avoid the possible loss of the
database cursor. In this case, the current work process waits until all data has been received.
