How to fix this error?

When troubleshooting, follow the steps described in SAP Note 944221.
First check the connection to ADS. You can use the program
FP_PDF_TEST_00 to do this. From SAP NetWeaver Release 7.0, the program
FP_CHECK_DESTINATION_SERVICE must also run successfully (both with and
without the checkbox selected on the selection screen). If this program
does not run successfully, there is a error in the configuration.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
