Check this link,

Please have a look in the 'SAP ERP Solution Browser' (Customer tool to identify new features and functions with focus on SAP ERP )

http://solutionbrowser.erp.sap.fmpmedia.com/

There you can define the 'Source/Target' Release Versions and the delta functionality will be available.

There is lot difference between 4.6c and 6.0

  • ecc 6.0 coming with inbuild webdynpro , BSP it is not 4.6c

  • In ecc we have interactive forms concept where it was not there in 4.6c

  • 4.6c there is no unicode concept here we have unicode and non unicode

From the ABAP perspective,

The WS_* function modules used in 4.6c has become obsolete from 4.7C. All the WS_* FMs have been replaced by GUI_* FMs.

(ii) Concept of Unicode is introduced.

(iii) Few tables have been modified in ECC6.0.

Tables TVARV & TTREX have been replaced by TVARVC & TTREXN respectively.

Hi,

Check some of the unicode error messages and solutions below:

1. Error:In "TEXT MODE" the "ENCODING" addition must b

Sol: We need to add 'ENCODING DEFAULT' Statement at the end of the OPEN DATA SET statement

2. Error:For Tab delimeter they are using ASCII values like '09' but in unicode it won't support

Sol:we need to CL_ABAP_CHAR_UTILITIES=>HORIZONTAL_TAB constant. For any Special characters use this Class constants.

3. Error:If there is an internal table with include structure and that structure is Deep structure

Sol:We should replace that internal table with that structure type standard table of

4. Error:WS_UPLOAD, UPLOAD ,WS_DOWNLOAD and DOWNLOAD FM's Should replace with GUI_DOWNLOAD and GUI_UPLOAD

Sol:Replace with GUI_UPLOAD and GUI_DOWNLOAD and check the import and export parameter types , do the changes accordingly. Because FILENAME paramater type is different because of this it will give dump.

5. Error: Issue using SO_NEW_DOCUMENT_ATT_SEND_API1 Function module

Sol:After this FM we should put COMMIT WORK

6. Error: In Print programs if there is any selection parameter type 'nast'

Sol: First check this paricular print program is calling from any other program using SUBMIT statement then add NO-DISPLAY option at that parameter level.

Reward points if helpful.
