standard data source deleted after a copy

Hi gurus!,

I was trying to make a change into the data source  CRM_COMPLAINTS_I inside CRM system because I did not want to changge the standard one.

However, I copied it as ZCRM_COMPLAINTS_I , after that I can not use the standard data source CRM_COMPLAINTS_I.

I can see and activate it at the RSA5, but once I try to test the data at the RSA3  I can see this message:

"DataSource CRM_COMPLAINTS_I is not defined in the source system"

Message no. RJ002

How can I use it again? I have tried activating it at the RSA5 but no success by now.

Any suggestion?

Regards.
