hi,

When u use default value for the parameter it is contants.

but when use initialize in inilize event value u specify is dynamically generated.

eg :-

initialize.

para1 = sy-datum + 7.

select something from table into itab

para2 = itab1-key1.

feel free to ask any question.

Hi,

adding to above you cannot give default values for select options like include, exclude, between , equal options that can be done only with initialization event.

dynamic defaults can be done in initialization , you cannot default in selection screen with dynamic values as stated above.

Hi nikita,

1. good question.

2. when we use default,

we have to HARDCODE the value in the program.

3. but suppose, u want to

pick some field from database,

and show it as default,

then,

DEFAULT won't work.

(bcos we have to write code for getting data first)

4. In such cases, we use INITIALIZATION event.

5. Other wise there is no difference.

amit m.

Hey vijay

we can assign default values to sign (I,E), option (LT,GT..)fields of select options using

select-options fnane for <ref> default sign..option..

Hi nikita,

Check the Amit answer for dynamic values .if you want to assign certian data from data base to selection screen then you need to go for initialization.

Nikita,

Unless you append the I,E, LT, GT values, it will not be reflected in the SELECT-OPTIONS, right and you cannot use the append option it the DEFAULT setting.

If you have process something before you arrive at a value that cannot be done in DEFAULT, where as you can do that in INITIALIZATION.

GOOD

PARAMETERS

Declares parameters for a selection screen.

Syntax

PARAMETERS <p>[(<length>)] [TYPE <type>|LIKE <obj>] [DECIMALS <d>]

[DEFAULT <f>]

[MEMORY ID <pid>]

[LOWER CASE]

[OBLIGATORY]

[VALUE CHECK]

[AS CHECKBOX]

[RADIOBUTTON GROUP <radi>]

[NO-DISPLAY]

[MODIF ID <key>].

SELECT-OPTIONS

Declares selection criteria for a selection screen.

Syntax

SELECT-OPTIONS <sel> FOR <f>

[DEFAULT <g> [to <h>] [OPTION <op>] SIGN <s>]

[MEMORY ID <pid>]

[LOWER CASE]

[OBLIGATORY]

[NO-DISPLAY]

[MODIF ID <key>]

[NO-EXTENSION]

[NO INTERVALS]

[NO DATABASE SELECTION].

THIS IS THE WAY TO PASS THE VARIOUS PARAMTERS IN SELECT-OPTIONS AND PARAMTER STATEMENTS, AND YOU CAN USE THEM AS PER YOUR REQUIREMENTS

THANKS

ya Ravi u r right

but that will be the case if i want to add more than one record to the selection table

But if i just wann give single record than that i can do using default addition without using Initialization Event

Isnt it??

Nikita,

Yes that is the case even if you have append one record to the SELECT OPTIONS, Unless you append it, that same will NOT be considered, and you cannot APPEND while defaulting, right?
