When attempting to rewrite a record after moving/changing one of the components of the key, it hits a error - ie. duplicate key. But after investigation using sql, there is no such existing key value in the database. Why is this happening ?

Thanks. We'll let you know when a new response is added.

Search the duplicate record in the INPUT file.
///////////////////////////////
Focus on the keyfields of the primary – use DSPFD to determine the keys
The value of the combined key fields must be unique.
Check for logical files – DSPDBR physical
if any of these are UNIQUE then their keys also cannot be duplicated.
Check your code – you maybe attempting to write the same record twice.
