hi,

Unicode check using transaction UCCHECK.

syntax check

code inspector check.

text element conversion.

replacement of old FM.

The basic steps are :

To upgrade the ABAP development:

Compile all programs and resolve syntax errors associated with the ABAP development.

Test the new environment and make modifications as needed.

Modify the program as per Unicode compliance (if required)

This is not needed when upgrading to ecc 6. Its only needed when changing to a unicode system. An ecc 6 system is not necessarily a unicode system.

That true that we can have one-code pages script and a non-unicode system, but it makes no sense. SAP is pushing everyone to unicode for

good reason, it cuts down substantially on the amount of kernel

support they will have to do in the future as well as simplier

logistics and installation in getting patches and upgrades to

the client.

So unicode check is very essential....

Along with this there are many Function modules which are obselete. They also need to be replaced.

1.Initially make your programs Unicode Enabled (in Attributes)

2.By using UCCHECK txn,check for the syntax error of the program and change accordingly.

3.Have to replace obsolete functions/syntax according to ECC 6.0

4.Have to change syntax which supports ECC rather than 4.6C

hi,

there is a big list of dos and dont.....

some errors are:

Syntax Error:

REPORT/PROGRAM statement missing, or program type is INCLUDE.

Unicode Error

Upload/Ws_Upload and Download/Ws_Download are obsolete, since they are not

Unicode-enabled; use the class cl_gui_frontend_services

Syntax error

TEXT E00 is not defined in text pool of ZSTEXTEM in the

original language E

Error message in ABAP Objects if the following syntax is used:

NEW-PAGE PRINT ON NO DIALOG.

Correct syntax:

DATA pripar TYPE pri_params,

arcpar TYPE arc_params.

CALL FUNCTION 'GET_PRINT_PARAMETERS'

IMPORTING out_parameters = pripar

out_archive_parameters = arcpar

...

NEW-PAGE PRINT ON NO DIALOG

PARAMETERS pripar

ARCHIVE PARAMETERS arcpar.

The list continues................ do a google or search for documentations
