When we deploy the workflow in the enterprises folder, we may get below error and unable to deploy the same.

SQL-8202: Failed while executing SQL statement. SQL state 23000. Database specific error code (if any) was 1. Database error message (if any) was: java.sql.BatchUpdateException: ORA-00001: unique constraint (XXXXX.XPKPROCESSDETAIL2) violated.

Below are possible reasons for the mentioned exception.

1) With same name workflow already exists in the enterprise folder.So,We need to give unique name to the deploying workflow file.
2) There may be some duplicate parameters present in any one of the activities.we need to avoid the duplicate parameters present in the workflow activities.
