Answer -
Are both chains to the same file name, or are you using the same file under two names?  If both chains are to the same file name, then as soon as your program chains the second time to the file, the first lock is released automatically, so you should not be getting a lock message.  If you are using the same file under two names, then after the first chain you have locked the record - if you try to chain to the same record a second time for update, you will get a lock message.

Answer
The problem does not make sense.  Any lock you have on a record is automatically released when you chain to another record in the same file.  Could there be another process running that has the record locked for update?  You might use the WRKOBJLCK command to check for any other program which might have a lock.
