Data is received in the buffer input in accordance with the buffer length. After the call, rec_length
contains the number of bytes placed in the buffer. The DATAINFO and STATUSINFO fields contain
information about the call.
If a RECEIVE occurs in send mode, the right to send is transferred to the receiving program, together
with any existing user data in the network buffer. The sending program then assumes RECEIVE mode.
You must assign appropriate types and lengths to variables:
ABAP/4: C:
CONVID C 8 convid
PCONVERSATION_ID
INPUT C max. 30,000 input PCPIC_CHAR
DATAINFO X 4 data_info PDATA_RECEIVED
STATUSINFO X 4 status_info PSTATUS_RECEIVED
REQ_LENGTH P requested_length CPIC_INT (max.
30,000)
REC_LENGTH X 4 received_length CPIC_INT
RC X 2 rc CM_RETCODE
request_to_send_received
PREQUEST_TO_SEND_RECEIVED
If the HOLD parameter is set, the current work process is kept (no roll-out, roll-in).
