Design around Event message buffer concept

Hi Expert ,

I am designing a process around event message buffer concept .

I have a requirement where event should not be posted in EM if a specific indicator is not set in control parameter . In this case , event message should be saved in buffer and a batch job should be set which will try to process buffer event message .

These buffer event message should be processed if specific indicator is set otherwise message should again be stored in buffer .

There is a configuration where you can define the condition when event message should be buffered . However required field are fixed and there is no possibility to check specific indicator (control parameter ) .

Do you any idea how can I make use of above mentioned configuration for buffering event message .

Otherwise I do not think we have possibility to write a code in preprocessing function module to buffer message based on condition . Do we ?
