hi,

Rajneesh.

if in a saelction screen if user entered wrong value then if u throw a error message then again user cant enter anthing in tht screen

but if the fields are given in between chain and endchain then even though u through the error message the user will be in the same screen and also he can reenter the value he enterd

Hi,

To ensure that one or more PAI modules are only called when several screen fields meet a particular condition, you must combine the calls in the flow logic to form a processing chain. You define processing chains as follows:

CHAIN.

...

ENDCHAIN.

All flow logic statements between CHAIN and ENDCHAIN belong to a processing chain. The fields in the various FIELD statements are combined, and can be used in shared conditions.

CHAIN.

FIELD: <f1>, <f 2>,...

MODULE <mod1> ON CHAIN-INPUT|CHAIN-REQUEST.

FIELD: <g1>, <g 2>,...

MODULE <mod2> ON CHAIN-INPUT|CHAIN-REQUEST.

...

ENDCHAIN.

Fundamentally, computers store letters and other characters by assigning a number for each one.

Unicode provides a unique number (Code point) for every character, no matter what the platform, no matter what the program, no matter what the language.

Notation U+nnnn (where nnnn are hexadecimal digits)

Unicode = universally encoded character set to store information from any language

The Unicode standard primarily encodes scripts rather than languages

• Scripts comprise several languages that historically share the same set of symbols

• In many cases a script may serve to write dozens of languages (e.g. the Latin script)

• In other cases one script complies to one language (e.g. Hangul)

Additionally it also includes punctuation marks, diacritics, mathematical symbols, technical symbols, musical symbols, arrows, etc.

In all, the Unicode Standard comprises >95.000 characters, ideograph sets,

Unicode Standard:

The Unicode Standard is a character coding system designed to support the worldwide interchange, processing and display of written text of the diverse languages and technical disciplines of the modern world.

In addition, it supports classical and historical texts of many written languages.

The Unicode Consortium:

The Consortium cooperates with

W3C

ISO

and has liaison status "C" with ISO/IEC/

JTC1/SC2/WG2, which is responsible for in refining the specification and expanding the character set of ISO/IEC 10646

Hi,

normally in abap char occupies 1 byte of memory and in unicode program char occupies 2 bytes in this way it is different.

if we get an error in the screen while user entering wrong information the fields will get disabled if we want to give the chance to user for reentering then we have keep that all the fields in chain and endchain.

plzzz reward points if it is helpful.
