Former Member — Fri, 06 Jul 2007 03:44:25 GMT

i have created a push button on my selection screen. i want to call a perform by clicking this pusbutton. now the problem is in my perform, i have called the same screen, in which i have included my push button. i have written this in the event

at selection-screen output. So there is a dump thrown by SAP. the problem is it is going into calling the the screen infinite number of times. moreover i cant use

at selection-screen, as im doing a BDC recording, so the include of BDC, which comes into the program by default, already has at selection-screen event. so if i declare it in my program its also throwing an error.So, can some body help me in giveing a solution to this problem.

eg. i want to do some validation and want to print it by clicking my push button for a given pernr and for a given date.

Try using a flag variable and set it to true and false...so that the iterations happens only once.

Hi,

Use event AT USER-COMMAND. Whatever you want to do after clicking the push button, write that code under this event. So, whenever you click on the push button, this event will be triggered and hence your code will be executed.

Perform display_output.

endcase.

Hi Madhvi,

Have you attached a function code to your push button ? If not, please do that, because without that, AT USER-COMMAND event wont be triggered.
