Hi,

Just use:

   
      DATA:objtxt LIKE solisti1 OCCURS 0 WITH HEADER LINE,
         EDITOR-CALL FOR objtxt.

In case you want in 'protect mode' or 'display mode' then use


          EDITOR-CALL FOR objtxt DISPLAY-MODE.

I hope this helps,

Hi,

Sorry for the delay, please find the info on the constants I have used:

c_dis_03 = '03'. " Display

c_create_01 = '01'. " Create

c_change_02 = '02'. " Change

Let me know if anything else is required and hope the solution I have provided helped you.
