"Match Code Object is now created and activated.

Matchcodes are an SAP technique to help users find information, normally in

connection with the F4 key on an input field. Information from one or more

tables can be combined and queried on using various search criteria: for

example, all companies whose name starts with "TATA" and whose location is

"INDIA."

Traditionally, matchcodes were implemented as redundant collections of data

in pool tables, as illustrated in the following:

Company header table Company detail table Matchcode pool table

(TAB1) (TAB2) (M_POOL)

The advantage of the old pool matchcodes was a quick and easy search, as

long as the significant fields were entered by the end user (in this case,

company name and location). The disadvantage was that for every change in

the master tables, the system had to make redundant updates in the matchcode

tables. In addition, it was impossible to search in a pool matchcode for any

but the significant fields, i.e., it would have been very CPU intensive to

search for all companies in San Francisco.

This limitation led to the creation of matchcodes (more precisely, in SAP

terms, "matchcode IDs") for every possible query you could expect from end

users (one with company name as the significant field, one with location,

yet another with customer number, and so on). Customers with a very high

number of debitors, for example, soon found that their pool matchcode tables

grew to unmanageable sizes.

As of release 2.1, it is now possible to define so-called transparent or

view matchcodes. Transparent matchcodes are implemented by defining a

database view for the information that should be queried. Database views are

not redundant containers of data, but are merely definitions of paths to

obtaining that data. In the example:

Company header table Company detail table Database view:

(TAB1) (TAB2) (M_VIEW)

The advantage of this new technique is that it is no longer necessary to

maintain redundant matchcode data: a view takes only a small amount of

database dictionary space. Using this technique, the query is converted by

the database to a query against the original tables, so it becomes very

important that access be supported by the proper indexes.

Hi

In which version of SAP are you working?

Matchcodes are replaced by SEARCH HELPs in latest versions

see the doc

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 ..

Collective search help Combine several elementary search helps. A collective search help thus can offer several alternative search paths.

A Collective search help provides alternative search

Paths by combining elementary search helps.

Only one search help can be attached to a field, table or data element. Several search paths are therefore attached with a collective search help.

A collective search help also has interface parameters like

an elementary search help.

Like an elementary search help, a collective search help has an interface of IMPORT and EXPORT parameters with which the search help exchanges data. Using this interface, the collective search help can be attached to fields, tables and data elements exactly like an elementary search help.

Parameter assignment needs to be done for each of the

Included search helps.

When you define a collective search help, there are no components for describing the dialog behavior and data selection; instead the included search helps are listed here. You must assign the parameters of the collective search help to the interface parameters of the included search help for each inclusion.

User may choose the tab and thus the elementary

search maethod.

When we execute the search help SCUSTOM, we are confronted with a dialog which gives us an option of either restricting

By 1)Search for customer according to booking

2)Search for customer according to name.

These are effectively the elementary search helps (SCUSTOM_BOOK and SCUSTOM_NAME) which have been included in the collective search help SCUSTOM.

HOT KEY

The hot key is used to select the elementary search help from the collective search help and to enter the restrictions in the dialog box for restricting values directly from the entry field. If the user often searches for values using the same search help, this procedure can save time.

Steps to create a Collective Search Help

1)Enter the search help name and click on create.

2)Choose Collective search help radio button option as the search help type.

3)Enter the search help parameters.

4)Instead of the selection method, we enter the included

search helps for the collective search help.

5)We need to assign parameters for each of the included

search helps.

6)Complete the parameter assignment by clicking on the push button

7)Collective search help offers the user to obtain F4 help

using any of the included search helps.

Match Code is nothing but a search help.

you can create one in se11 if its a report the declare like this in selection screen

p_id like zxxx-id obligatory matchcode object zmatch.

create a match code in se11 for vendor master say!!

if its dialog program

then in the attributes of the field under search help give zmatch

IF YOU WANT SEARCH HELP BASED ON MULTIPLE THING THEN YOU HAVE TO GO FOR COLLECTIVE SEARCH HELP WHERE YOU LIST ALL YOUR ELEMENTARY SEARCH HELPS

LIKE IN HERE

VENDOR BY COMANY,VENDOR BYCUSTOMER ETC ARE ELEMENTARY SEARCH HELPS

Vendor if you see the Search Help, it gives you the option for Vendor by Customer, Vendors by COmpany Code etc etc.

THEN YOU CREATE A COLLECTIVE SEARCH HELP WHERE YOU GIVE ALL YOUR ELEMTARY SEARCH HELP.

SI IF YOU WANT TO ADD TO THIS LIKE

Vendor by Customer, Vendors by COmpany Code ,VENDOR BY TAX NUMBER1

GO TO SELL CREATA ASEARCH HELP ZTEST

GIVE SOME SHORT DESC

THEN IN SELECTION METHOD GIVE THE TABLE I.E LFA1

THEN UNDER SEARCH HELP PARAMETER

GIVE

LIFNR SELECT IMPORT EXPORT LPOS 1 SPOS 1 AND PRESS ENTER

BELOW THAT

STCD1 LPOS2 SPOS 2 AND THEN PRESS ENTER

SAVE IT.

THEN FIND THE COLLECTIVE SEARCH FOR VENDOR FIELD AND JUST THIS TO IT.
