Hello.
PARAMETER_CHANGE has several optional input parameters.
What are the effects of running PARAMETER_CHANGE with no parameters? Will it update anything?
Thanks.
Zenon.
Hello Zenon,
if the values from the Event Message are initial then the values from the customizing are used.
e.g. the sender of the message does not know your parameter type then you can set it hard to Control in the customizing.
Best regards,
Steffen

Hello Zenon,
just to give you another example. If you are sending additional parameters from the application system and all parameters should have the same parameter type or all of them should be added you don't need to fill this in the application system.
So in the Event Message extractor instead of filling all input parameters like this:
ls_trackparameters-evtcnt = gv_evtcnt.
ls_trackparameters-partyp = gc_control.
ls_trackparameters-param_name = 'PO_LATEST_ACK_DATE'.
ls_trackparameters-param_value = <ls_xekes>-eindt.
ls_trackparameters-action = gc_change.
you would just fill it like this:
ls_trackparameters-evtcnt = gv_evtcnt.
ls_trackparameters-param_name = 'PO_LATEST_ACK_DATE'.
ls_trackparameters-param_value = <ls_xekes>-eindt.
Parametertyp and action would be entered in the rule set. So in case you would have to change the parameter type in future you would just do a change in the customizing. But keep in mind that this works only if you have the same parameter type or the same parameter action for all parameters of the Event Message.
Best regards
Berthold
