Conflicting Unique indexes - CRM upgrade stopped

Hi Friends,

We are getting the below error in pre-processing step of CRM upgrade from CRM 5.2 to CRM 7.0 EHP 2.0

"Checks after phase MAIN_SHDIMP/SUBMOD_SHDIMP/SHADOW_IMPORT_UPG2 were negative!

Last error code set: Detected 128 errors summarized in 'SHDUPGIMP2.ELG'<br/> Calling '/dataexport/SUM/abap/exe/tp' failed with return code 8, check /dataexport/SUM/abap/log/SAPup.ECO for details"

Detail from SHDUPGIMP2.ELG:

"2EETW000 Update and insert sequence failed due to conflicting unique indexes on table COMC_ATTRIBUTE (please read OSS note 626915 for details)"

I have dropped the index at DB level.

Any suggestion on how to proceed further..

I have attached the below files



    Error screenshot & Table details at DB level

System details:

CRM 7.0 EHP2.0 , Oracle 11g

I have referred the below,


SAP Note : 626915

Thanks in Advance

Thanks, Ganesh

    Hi Ganesh,

    As per SAP Note 689574 - Add. info. on upgrading to SAP ERP Central Component 5.00

    Similar issue has been addressed.

    Solution is :

    delete the primary index of the respective table and recreate it. Repeat the upgrade phase

    Hope this helps.

      Hi All,

      The issue is solved,  below are the steps. Thank you all for the suggestions.

      Solution :

      1. Created the unique index "COMC_ATTIBUTE~UNI"at SAP level in SE14

      2. Renamed  the unique index from "COMC_ATTIBUTE~UNI" to "ZDROPINDEX" at DB level instead of deleting it.

      3. Retried the main import phase in SUM.

      Thanks, Ganesh
