This issue happens just in this report or other more reports? You have PL04, but which SAP B1 version?
If you have in 8.81, then I recommend to upgrade to latest PL of SAP B1 8.82 as minimum.
Also, if you use a ODBC connection, you can trying to update the data source from Crystal Design from ODBC to SAP B1 connection.
Best regards.
