Hello

You should not use ABAP keywords (CLASS) as name of your class. Replace it with lcl_myclass or something else.

Hi,

The error in your program is remove the space before display.This solve your problem.

replace call method CLASS-> DISPLAY with CAll method CLASS->DISPLAY.

Reward if useful.

Regards,

Swetha.
