Dear all,

can anyone tell, what is the difference between

screen-required = 0 and

screen-required = 1.

A quick search at help.sap.com tells me this :

quote http://help.sap.com/saphelp_nw70/helpdata/en/d1/801c54454211d189710000e8322d00/frameset.htm

• required

Input/output fields must be assigned an input value at runtime. The system checks this input at once when processing the PAI event.

Required fields are indicated by a question mark "?" as the first character. (Exception: If the field lies in a table control or step loop, the question mark is not displayed.)

The selected value can be modified at runtime with LOOP AT SCREEN, field SCREEN-REQUIRED:

• 0 neither a recommended nor a required field

• 1 required field

• 2 recommended field

when you change the screen required value from 0 to 1 for a particular field, the field becomes mandatory(Value must be entered).

If your query is answered kindly close the thread and award points.

screen-required = 0. ==> not mandatory.

tables: vbak, SSCRFIELDS.

DATA FLAG(10).

**SELECTION-SCREEN BEGIN OF SCREEN 001 AS SUBSCREEN.

SELECTION-SCREEN BEGIN OF BLOCK D1 WITH FRAME TITLE TEXT-001.

SELECTION-SCREEN PUSHBUTTON /10(8) text-001 USER-COMMAND 1.

SELECTION-SCREEN PUSHBUTTON /10(8) text-002 USER-COMMAND 2.

SELECTION-SCREEN PUSHBUTTON /10(8) text-003 USER-COMMAND 3.

SELECTION-SCREEN PUSHBUTTON /10(8) text-004 USER-COMMAND 4.
