5. Bring out the default value of the field

For non-editable fields that need to be automatically assigned values, you can use SE54 table maintenance events or screen events, which are demonstrated below.

(1) Method 1: Table maintenance event

In the table maintenance interface: Menu, Environment → Modify → Event
Insert image description here
Add event: 21-Fill the hidden field, customize the FORM name: FRM_FILL_DATA.

Click the code editor, select the included file, and add the following FORM code:

form frm_fill_data.
  IF ztbcehlist-erdat IS INITIAL.
    ztbcehlist-erdat = sy-datum.
    ztbcehlist-uzeit = sy-uzeit.
    ztbcehlist-ernam = sy-uname.
  ELSE.
    ztbcehlist-lstdate = sy-datum.
    ztbcehlist-lsttime = sy-uzeit.
    ztbcehlist-lstuser = sy-uname.
  ENDIF.
ENDFORM.

Save and activate to realize automatic generation of new information and maintenance information.

(2) Method 2: Screen events

In the table maintenance interface, double-click the screen number, enter the Screen-Logical Flow tab, and
add the following code in the screen flow logic:

and select the included file, and add the following MODULE code:

MODULE zset_date_time INPUT.
  IF ztbcehlist-erdat IS INITIAL.
    ztbcehlist-erdat = sy-datum.
    ztbcehlist-uzeit = sy-uzeit.
    ztbcehlist-ernam = sy-uname.
  ELSE.
    ztbcehlist-lstdate = sy-datum.
    ztbcehlist-lsttime = sy-uzeit.
    ztbcehlist-lstuser = sy-uname.
  ENDIF.
ENDMODULE.
