CREATE APPEND STRUCTURE IN ABAP DATA DICTIONARY

APPEND STRUCTRURES :


             APPEND STRUCTURES ARE USED ONLY TO ENHANCE STANDARD TABLES.  STANDARD TABLES MAY HAVE INCLUDE STRUCTURES ALREADY CREATED , BUT IF WE WANT TO ADD SOME MORE FIELDS TO THE STANDARD TABLES, WE NEED TO GO FOR APPEND STRUCTURES.

            APPEND STRUCTURES SHOULD BE ADDED AT THE END OF A STANDARD TABLE. THIS IS A MUST. BECAUSE WE SHOULD NOT CHANGE THE ORIGINAL STANDARD TABLE IN THE MIDDLE.

• ONE THING YOU SHOULD KEEP IN MIND THAT IT MUST BE CREATED IN CUSTOMER NAMESPACE.
• AND THE OTHETHING IS THAT NAME OF APPEND STRUCTURE MUST BE STARTS WITH  ZZ OR YY 
• Let's starts with  BKPF (Account Document Header) Table .

DIFFERENCE BETWEEN ELEMENATRY & COLLECTILE SEARCH HELP

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. 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 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 collective search help, they are expanded to the level of the elementary search helps when the input help is called.
