Summary :
SAP Note addresses the error AQ898 'Convert first' encountered in systems installed with R/3 release higher than 4.0A, when accessing SAP query components like queries, InfoSets, or user groups. The error incorrectly prompts for conversion, suggesting an upgrade akin to Note 92124 from 3.x to 4.y releases, which isn't applicable to new installations. This occurs because the system cannot distinguish between new installations and upgrades. Resolution ensures recognition of existing 3.x query objects; absence indicates a new installation, permitting standard area operations. Fixed in standard from Release 5.0A, and available in Support Packages for 4.6x releases.
