KEA0 Error generating client-specific objects

Dear SAP Gurus,

Hi, currently we are in configuration phase.

I want to activate operating concern 1000 via KEA0.

Cross client part activated successfully, but for client specific part it is failed in around 90++%.

We have browsed solution in internet & forum but still we face the error.

Did i miss something in configuration ?

Please kindly help.

Best regards,

FreddyHa
