Getting error while importing CRDelta file into SLD

When we are applying SAP Note 669669 - Importing delta in SLD we are getting the below mentioned error message.

"The selected aggregate import is not applicable to the current version SAP_CR2.0 of the target namespace"

We are trying to import the zip file CRDelta1511_0-10004549.ZIP.

However we were successfully able to import the cimsap1511_0-10004549.zip into the SLD successfully.

We are doing this import activity (upgrading the SLD) as we are unable to locate the ESS related mandatory Software Component EP_BUILDT in the current SLD version.

Waiting for a quick response

Regards,
