all the customizations need to be checked manually...

there no other option to that...

if you have documentation of all the customization in the system then it might help in understanding importance of the customization....

as it is very sensitive issue you need to check each and every object carefully & manually

It's not a job for you I think, it's a job for your department as upgrading SAP is very tedious and requires a lot of testing from the current version you have now to the new version you are installing. Upgrade required you to do a similar testing between the old and the new. So this will require a lot of man hours and man power.

The best way is firstly run it in the 4.6 if is is successfull .. trf it to dummy ecc6 run it and if the reaction is the same and everyting is good then only trf it to live systemm

its lengthy but its is safest.

Hi,

You can have a look at note 928729 - Combined Upgrade & Unicode Conversion.

The following links provide you with good documentation on upgradation from 4.6C to ECC6.0.

A complex task it is indeed. To get you on the right track:

1. Download the upgrade guide relevant to your landscape; Architecture, database

(http://service.sap.com/instguides)

2. Study the SAP Notes referenced in the upgrade guide.

3. Order the SAP Going Live Functional Upgrade Check from SAP. (You are allowed two sessions free of charge - one before and one after the upgrade). This will provide information amongst other, whether your H/W is capable of handling the additional load of the new release.

4. Plan for H/W upgrades if necessary

5. Consider the effect of the upgrade on other SAP and non-SAP systems you have connected and which may be affected by the upgrade.

6. Plan and document the testing of your business scenarios

7. You will need to have installed SAP Solution Manager to perform the upgrade. This will give you the necessary upgrade key.

8. Plan for O/S and Database Upgrades

9. Carry out the upgrade in this sequence: DEV, Q/A, PRODUCTIVE systems.

The actual upgrade consists of two modules:

a) PREP - Can be run during productive operation and will perform initial checks of your systems

b) SAPup - This is the actual upgrade. You will need to choose between two strategies: downtime-minimized or resource minimized.

I find it very essential to create your own upgrade scripts with all the actions that need to be carried out before PREP, after PREP, before SAPup and after SAPup.

Hope this helps you. All the best.

Reward if helpful.

Hi,

Goto SE16 transaction

1. Check table contents for TADIR with Program = Z*

2. Tables and other dictionary objects: Tables DD0*

Get all the list of Z* objects.

For reports/dialog programs, you need to manually check whether its report/BDC etc.

Use program "RPR_ABAP_SOURCE_SCAN" to check for "BDCDATA" string.. It will list all the BDC. SImilarly you can do for others as well.

Best regards,

Prashant
