what happens when the entry for a developer is deleted in the DEVACCESS table but the developer continues to use the same user ID? The answer is that the developer can still use the old developer access key.
The reason: Developer access key is nothing but an algorithm based on system number and SID and some other system values (SAP does not reveal the information). The developer access key is validated by SAP using a Kernel level C system program ''CHECK_DEVELOPER_KEY'. So, even if the developer access key has been deleted for a user ID in the DEVACCESS table, she can still use the same developer access key.
Can anyone explain the above query in detailed ?
