Hi

You need to create Object for the Reference Variable REQUEST like as below code

Create Object Request .

Then you can use that Variable Request to call any component of the CLASS which referred by the Variable Request   .

Thanks ,

Hi guys,

Thanks for your answers.

The isse is that i don,t know the class name, when i click on get_form_fields, the system doesn,t take me to the class.

I have instead an error message :

Incorect cursor position.

Thanks.

Dear Amine,

This code is for a BSP page. You should create the BSP in transaction SE80 instead of SE38. This call should be added to oninitialization event.

Best Regards,

Look at the attached file please in my last message.

Hi,

Please provide ST22 dump analysis. I feel its better write sy-subrc check after assign component statement. so that you can avoid dump.
