Encrypt the code in designer

Hi,

We have used auditing universe and modified it as per our requirement. We have also developed some custom reports on that universe. We would like to know if there is any way we can encrypt the developed reports on designer level or on report level where the end customer cannot make changes to the code. The customer should not be able to make any modifications as we have designed and developed the reports.

Version :SAP BI 4.2 SP8

Please let us if we have any such possibility.

Thanks
