ECC System , what is th major difference - with a developer point of view?

[Former Member]

If in an interview I am asked what are some differences I noticed in the ECC system and SAP 4.7, what should be the perfect answer for a ABAP developer?

I haven’t worked much in ECC system and noticed the changes with debugger.

Also if I have some report , forms or function module in SAP 4.7 ,can anyone tell me if I can copy them directly to a ECC system or do I have some particular steps or prerequisite to follow before that , if explained with example it will be helpful?

From the ABAP perspective, i will give out a few differences.

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 All the WS_* FMs have been replaced by GUI_* FMs.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Tables TVARV & TTREX have been replaced by TVARVC & TTREXN respectively.

You can use this website for finding the differences between the 2 versions.

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

Check these differences.

1..For installing ECC 6.0 you required a solution manager key.With out solutionmanager key you cannot install ECC6.0.

2.For ECC 6.0 is called netweaver component here you have ABAP+JAVA stack.

ECC6.0 supports UNCODE.

3.For installing 4.6 you don't require solution manager key.It only having ABAP stack. 4.6C supports NONUNICODE.

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 All the WS_* FMs have been replaced by GUI_* Function modules

5. Few tables have been modified in ECC6.0.Tables TVARV & TTREX have been replaced by TVARVC & TTREXN respectively.

Major difference is ECC6 is netwear product having WASJAVA+ABAP

Thanks for all your reply, but still my question is not completly answered.Say for example I have some User exit or function module or a smartform which I have implemented in 4.6 or 4.7. Now in an upgrade project I need to implement this in ECC system. The installation of this system is already taken care.

What are the steps I need to follow? Do I need to only copy the same code into ECC as in 4.7 system or would there be some other requirements too.

In brief what does an ABAP developer do in an upgarde project?

Thanks and Regards
