The different options are given in the case statement with the order of execution. When a search help exit is assigned to a search help and the search help is assigned to a i/P parameter, when the user press the F4 option, then the search help exit function module is executed multiple times with different events. In the tables section we have also two parameters with the below predefined name. In the changing section we have to predefined parameters. This is a special function module which is used for the search help exit functionality. Lets create a Function group and inside that create a function module. So for that we have to create a search help exit. Here we want that when the user clicks on the F4 option, it should show only those records from SPFLI where the COUNTRYFR is US. So here the value of CONNID is assigned to the field P_CONNID. So here we receive all the records that are present in the table. So in the I/P field the F4 option available and click on the F4 option.

Now in the report assign the search help to the field and execute the report. Go to SE11 and create a elementary search help with the table SPFLI.

So with the field no search help is assigned, so no F4 option is available. Create a report and declare a parameter and execute it. These are the below records present in the SPFLI table. Search Help Exit is a function module with some predefined changing and tables parameter which is used to modify/filter the F4 values selected by Elementary or collective search help from the DB table.
