Hi ,

User command is used to handle GUI events in SAP.

For example if you want to trigger some event on 'BACK , ENTER, STOP' buttons which are on GUI menu bar. You use AT -USER COMMNAD events.

For more refer link :

[http://help.sap.com/saphelp_nw04/helpdata/en/9f/dba3ae35c111d1829f0000e829fbfe/content.htm]

The use of SET parameter is :

SET PARAMETER:

syntax:

SET PARAMETER ID <pid> FIELD <f>.

it is used to store a value of the field in sap memory and it is identified by parameter id(pid).

GET PARAMETER:

syntax:

GET PARAMETER ID<pid> FIELD <f>.

it is used to get data from memory location pid into the given field f.

Hope this will help you.

SET parameter :

this is used to pass a value from one report a memory n from there we can use in the same report or the other report..

SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement. Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens

Hope this helps u,
