Hi Rasheed,
go through this info.
You have to create a help view if a view with outer join is
needed as selection method of a search help.
The selection method of a search help is either a table or a
view.
If you have to select data from several tables for the search
help, you should generally use a database view as selection
method.
However, a database view always implements an inner join. If
you need a view with outer join for the data selection, you
have to use a help view as selection method.
The creation method for Help view is similar to that of
Database view.
The input help (F4 help) is a standard function of the R/3
System.
The user can display the list of all possible input values
for a screen field with the input help.
This standard process can be completely defined by creating a
searchhelp in the ABAP Dictionary. This search help only has to
be assigned to the screen fields in which they should be
available.
There are two types of search help:
Elementary search helps describe a search path. The elementary
search help must define where the data of the hit list should be
read from (selection method), how the exchange of values
between the screen template and selection method is
implemented
(interface of the search help) and how the online input help
should be defined (online behavior of the search help).
Collective search helps Combine several elementary search
helps. A collective search help thus can offer several
alternative search paths.
Each customer of a carrier or of a travel agency has a
customer number. You want to find a search option for this
customer number.
The user must be offered two different search paths.
1> The user should be able to search for the customer
number using the customer data, such as the name and
address.
2>The user should be able to search for the customer number
using existing customer bookings.
Two elementary search helps SCUSTOM_NAME (for searching
with the customer data) and SCUSTOM_BOOK (for searching
with the existing bookings) are created for the actual search
paths.
These elementary search helps are included in the collective
search help SCUSTOM.
Elementary Search Help SCUSTOM_NAME
This elementary search help should enable you to search for
the customer number using the name and address (street,
city, country).
All this data is contained in table SCUSTOM. Table
SCUSTOM must therefore be selected as the selection
method of the elementary search help.
For creation:
Procedure
1> In the initial screen of the ABAP Dictionary, select object
class Search help, enter the name of the search help and
choose Create. A dialog box appears in which you must
select the type of search help.
2> Select Elementary search help and choose .
The maintenance screen for elementary search helps
appears.
3> Enter an explanatory text in the field Short text.
You can for example find the search help at a later time
using this short text.
4> In the Definition tab page enter the selection method of the
search help. You can enter the name of a table or a view
(database view, projection view or help view) here. If you enter a
table that has a text table, the name of the text table is
automatically entered in the corresponding field.
5> Using the input help (F4 help), select fields of the selection
method as parameter in the Search help parameter area.
Select the fields that should be used in the dialog box for
value selection or in the hit list. If the selection method is a
table that has a text table, both the fields of the table and the
fields of the text table are offered in the
input help.
The data element of the parameter is automatically copied from
the selection method. The data element defines the output
attributes and the F1 help of the parameter in the hit list and in
the dialog box for value selection.
You can assign the parameter another data element. To do
so, select the Mod flag. The Data element field is now ready
for input. Then select a data element with the input help (F4
help). Only data elements whose data type, length and
number of decimal places is the same as those of the
previous data element can be assigned.
This removes the link between the data element of the search
help parameter and the data element of the selection method
field having
the same name. If you cancel the Mod flag, the data
element of the assigned table field is used again.
6> Define the attributes of the search help parameters.
Select the IMP flag if it is an import parameter. Select the
EXP flag if it is an export parameter.
7> Select the dialog type of the search help.
The dialog type defines how the hit list is displayed in the
input help.
8> Save your entries.
A dialog box appears in which you have to assign the search
help a development class.
9> Choose Activate .
Syntax:
PARAMETERS P_PARA1 MATCHCODE OBJECT <SEARCH_HELPNAME>.

Hai,
Basically you are not supposed to use differnetly the functionalities of F4 for Search help and similarly for Enter.
You want F4 help when you press Enter and Get initial screen of the transaction,Am i correct ?.
Yes, You can also do like that <b>Using Module Programming</b>.
You write the PAO Modules for the selection screen as below:
<b>CASE SY-UCOMM.
WHEN 'F4_HELP'.
CALL TRANSACTION SE11.(Tranction Name)
WHEN 'ENTER'.
CALL F4IF_FIELD_VALUE_REQUEST.(Function Modele for F4 Help)
ENSCASE.</b>
Hope You can proceed now.
<b>Reward points if it helps.</b>

Hi,
If you are using Your own elementary search help then, u can change the
Dialog type as 'DIALOG WITH VALUE RESTRICTION' in 'Dialog behaviour' property in 'Definition' Tab for that search help in SE11.After doing this then you can get selection condition before displaying List of F4 values.
