... MATCHCODE OBJECT search_help

Effect

This addition links the input field of the parameter to a search help search_help from the ABAP Dictionary. The name of the search help must be entered directly. For the input field of the parameter on the selection screen, the input help key is displayed. When the input help (F4) is requested, the user is displayed the hit list from the search help. When an entry is selected, the respective value is placed into the input field. If no search help for the specified name exists in the ABAP Dictionary, a message is displayed in the status line when the input help is requested.

The addition MATCHCODE OBJECT cannot be used together with the additions AS CHECKBOX or RADIOBUTTON.

Note

The predecessors of search helps in the ABAP Dictionary were socalled matchcode objects. * This is why you have the name MATCHCODE OBJECT for this addition. Matchcode objects that have not yet been replaced by search helps continue to be supported by this addition.

For example,

PARAMETERS p_carrid TYPE s_carr_id MATCHCODE OBJECT demo_f4_de.

hi sridhar,

Search Helps

A search help can influence the behavior of a field when the input help is called. The search help must be assigned to the field in order to do this. You have the following options for this assignment:

Attach search help to a data element / table or structure field / screen field / check table.

Conventionally search helps are attached to table fields or data elements. We shall see the same.

1)Choose the field name, click on search help tab and

provide the name of the search help.

A search help is attached to a field of a table or structure in the maintenance transaction for this table/structure, analogously to attaching to a table. You must assign the interface parameters of the search help to any fields of the table/structure. The search field must be assigned to an EXPORT parameter of the search help at this time.

2)Attach the search help to the table field

3)The search help ZSTRAVELAG_NAME is therefore directly attached to the field AGENCYNUM of table ZSTRAVELAG.

Attaching a search help to a data element

Provide the search help name and the parameter name

under the further characteristics tab of the data element.

If the input help of a field is defined by its data element, no further screen fields can be used in the input help.

Also note that the input F4 help would be available wherever the data element is used.

Attaching a search help to a screen element

A search help can be directly assigned to a screen field in two ways.

The name of the search help must be entered in the Screen Painter in the Attributes for the field in the field Search help.

The name of the search help can be defined for selection screens in ABAP reports in the PARAMETERS or SELECT-OPTIONS statement directly following the supplement MATCHCODE OBJECT.

However, input help is only available for this particular screen.

search help:

->adding f4 functionality is search help(adding help for any topic)

match code:

->adding search help for the input field is called as mathcode object

->Match Code is a tool to help us to search for data records in the system.

A matchcode is a tool to search for data records in the system. Matchcodes are an efficient and user-friendly search aid for cases where the key of a record is unknown. It consists of two stages one is Match code object and the other is Matchcode ID. A matchcode object describes the set of all possible search paths for a search term. Matchcode ID describes a special search path for a search term.

Both are same

in older versions they are Match codes

and in new versions it is search helps

see

1) 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).

2) Collective search helps combine several elementary search helps. A collective search help thus can offer several alternative search paths.

3)An elementary search help defines the standard flow of an input help.

4) A collective search help combines several elementary search helps. The user can thus choose one of several alternative search paths with a collective search help.

5)A collective search help comprises several elementary search helps. It combines all the search paths that are meaningful for a field.

6)Both elementary search helps and other search helps can be included in a collective search help. If other collective search helps are contained in a collective search help, they are expanded to the level of the elementary search helps when the input help is called.

CREATION:

Go to SE11 Tcode

select search help

give the 'z' search help name and create

select the selection method ur table name eg : 'mara'

dialog module 'display value immediately'.

add the field whatever u want and lpos = 1 and spos = 1 and check import and export parameter.

where left position when displaying and spos = search position

and then save and activate ..
