Field of the Dynpro/screen like IT1002 u0096 long text
I need to create a description field in a PA infotype, however, the condition is that this field has to be like the description field in the 1002 PD infotype.
I know that the important tables in PD are HRP1002 (TABNR), and HRT1002 (TLINE).
I know that the function modules to use are RH_OBJECT_DESCRIPTION_READ and RH_OBJECT_DESCRIPTION_WRITE
<b> How I would create or modify the Dynpro/screen in order to the field look like a text editor (description IT1002) ?.
How I would generate the reference number (TABNR ) ?</b>
