Hi All, 

1. Lock all users in your system, cycle the system to ensure all users are logged off.

2. Disable the batch user as well, to make sure no jobs are running.

3. Backup the input buffer file (should bein the trans\buffer folder). After backing up the file, delete the file.

4. Goto STMS and check the import buffer, press F5. The buffer should be empty now.

5. Return to SAINT and reimport the component, it should be successful now.
