Initialization Event

[Former Member]

Hi AbAp's

Can you please explain about Initialization event with below scinario.

tables: makt.

selection-screen: skip 2,begin of block ini with frame title text-000,

skip 2.

select-options s_matnr for makt-matnr default '401' TO '500'

option BT sign I.

parameters: p_spras type spras default 'EN'.

selection-screen: skip 2,end of block ini.

initialization.

s_matnr-low = 'A1000'.

s_matnr-high = 'A1004'.

s_matnr-option = 'BT'.

s_matnr-sign = 'I'.

append s_matnr.

p_spras = 'JA'.

O/P : s_matnr : 401 to 501.

p_spras : JA.

My Doubt is .

1.Value for p_spras is picking from intialization but s_matnr it setting from default value what the reason for this?

2.Check the value in internal table s_matnr first record is default record and second is appended

value which is from initialization process ,So Which event is occur first initialization or

selection-screen?

Load of program is triggering first and i guess default value is populating from that.

Hi

Initialization is the first event which is triggered . Its used to modify the output before the screen is displayed to the user.

Hi Viquar Iqbal ,

In parameters it is modifying from initialization but select-options it is not modifying from initialization.?.

Hi,

For parameters it is overwriting. For select options do like this (add REFRESH s_matnr.)

tables: makt.

selection-screen: skip 2,begin of block ini with frame title text-000,
skip 2.
select-options s_matnr for makt-matnr default '401' TO '500'
option BT sign I.
parameters: p_spras type spras default 'EN'.

selection-screen: skip 2,end of block ini.

initialization.

REFRESH s_matnr.

s_matnr-low = 'A1000'.
s_matnr-high = 'A1004'.
s_matnr-option = 'BT'.
s_matnr-sign = 'I'.
append s_matnr.

p_spras = 'JA'.

I think p_spras = 'JA'. is not under initialization statement.

Try this once.

tables: makt.

selection-screen: skip 2,begin of block ini with frame title text-000,
skip 2.
select-options s_matnr for makt-matnr default '401' TO '500'
option BT sign I.
parameters: p_spras type spras default 'EN'.

selection-screen: skip 2,end of block ini.

p_spras = 'JA'. 

initialization.
s_matnr-low = 'A1000'.
s_matnr-high = 'A1004'.
s_matnr-option = 'BT'.
s_matnr-sign = 'I'.
append s_matnr.

Hi Rajviji,

1.Value for p_spras is picking from intialization but s_matnr it setting from default value what the reason for this?

For P_SPRAS you are overwriting the value EN by JA (Check in debugging) for s_matnr you are just appending (Not clearing and appending).

2.Check the value in internal table s_matnr first record is default record and second is appended

value which is from initialization process ,So Which event is occur first initialization or

selection-screen?

INITIALIZATION is a event where as selection-screen is not.

Hi.

Initialization event will occur first.

when u execute the program this event is trigerred first and set the values which u have made

in initialization event.

And when u execute ur program the default values will e ignored and values set in initilalization event

will work

Hi Rajviji,

Try following code.

INITIALIZATION.

refresh s_matnr.----

---

Additional statement.

s_matnr-low = 'A1000'.

s_matnr-high = 'A1004'.

s_matnr-option = 'BT'.

s_matnr-sign = 'I'.

append s_matnr.

p_spras = 'JA'.

In Report, INITIALIZATION is the first event. It will trigger before AT SELECTION-SCREEN event.

It used to give default values to the selection screen fields using SELECT-OPTIONS statement.

INITIALIZATION.

REFRESH s_matnr.

s_matnr-low = 'A1000'.

s_matnr-high = 'A1004'.

s_matnr-option = 'BT'.

s_matnr-sign = 'I'.

append s_matnr.

p_spras = 'JA'.

Joan
