It means when the user does an action (e.g clicking on a button ), an event is triggered.When you click on a certain button for example, it returns a value to sy-ucomm.

You can just check its value ...

e.g

If sy-ucomm = 'ONLI'.

*Treatment.

else

....

endif.

Hi,

basically abap is an event driven language.

if one event triggerd then the block of code under that event will execute.

suppose you have one report and you didn't code any event to trigger then here you will

get dought that there is no event for my report and how will i get output.

by default start-of-selection will trigger and it leads to execute the select statement and

which in turn will get data into internal table.

event is nothing but a driven program.abap process drives this driven program when

it will executes and when it wont;
