ABAP Channels in Release 7.51
2. Suppressing standalone AMC messages
Length Restriction for AMC
The length restriction for messages that can be sent using AMC has been extended from approximately 30,000 bytes to approximately 1 MB. This limit can be increased even further by changing the profile parameter rdisp/long_messages/max_length.
The same applies to APC messages, which are sent with an attached client object using the interface IF_APC_WSP_CLIENT_CONN_ATTACH.
Suppressing Standalone AMC Messages
The new parameter I_SUPPRESS_ECHO of the method CREATE_MESSAGE_PRODUCER of the class CL_AMC_CHANNEL_MANAGER can be used to control whether
AMC messages can be sent to the current ABAP session or not.
