Hi,

You have to do the following steps;

1.check SPAU, SPADD, Unicode Conversions, Version Management, User exits, code reviews.

2.you have to check if any transaction or program gets short dump.

3. Unit & Integration testing.

Hi,

You have to check SPADD & SPAU correction & do the unicode convertions.

Check the program coding if any transaction gives short dump

(like syntax error, user exists etc)

You have to do Unit test.

Hi Harinath,

When it is a technical upgrade from a lower version to ECC6.0, many objects like includes, Function modules, reports, OSS notes, DDIC objects, BDC/Print programs, SAP scripts, screens will get affected due to the upgradation. So we need to check with all these objects.

So a developer should be aware of the following:

u2022Unicode programming is followed in ECC6.0. So we need to be aware of it to rectify certain Unicode errors which are likely to occur.

u2022You have to run the transactions SPAU & SPDD to check for list of standard & custom objects that needs modification in the upgraded version.

Check the below link to find more details on usage of SPAU & SPDD transactions

http://help.sap.com/saphelp_nw2004s/helpdata/en/60/d6ba7bceda11d1953a0000e82de14a/content.htm

u2022Should be aware of the objects that have become obsolete in ECC6.0. They have to be replaced by appropriate ones.

--> The WS_* function modules have been replaced by GUI_* FMs in ECC6.0 as WS_* FMs have become obsolete from 4.7

-->Tables like TVARV & TTREX have been replaced by TVARVC & TTREXN respectively in ECC6.0.

u2022In case of tables, we need to specify the Enhancement category.

u2022Due to up gradation, we will lose out some variants. So we should take a back-up before proceeding with the up gradation.

u2022In case of BDC programs, some field names will be changed. So they have to be named appropriately.

Hi,

Initially, when ever u started for Object in SPAU and SPDD. i would suggest to list out all the Inactive Object in System , U will get it in

SE80 -> Inactive Objects<-|

Firstly activate all the Inactive Object or Delete those are not in use.

Will help the BASIS Consultant working, to upgarde System where he need to pases thr Objects create in Y and Z.

Then , go for SPDD , which wil complete the DDIC , so that object getting activated in SPAU will not face any problem in existence of field. Complete all Object activation and test all possible Scenario used by client.

Hi Preeti,

As an ABAPer, your job will be to do the modification adjustments using SPDD and SPAU

SPDD is for standard object adjustments and SPAU for repository object adjustments.

Please go through the link mentioned below for clear understanding about modification adjustments.

https://wiki.sdn.sap.com/wiki/display/HOME/ERP2005+Upgrade

Also go through the OSS note 546801.
