OVERWRITE – Whether to overwrite an object during rename

When using NEW_ prefixes for fields when using Batch Loader in UPDATE or COPY mode, they will result in a new name for the object. This new name might point to another pre-existing object. By default, the update fails. The OVERWRITE option enables you to modify this behaviour to allow the replacement of the existing object.

N
The UPDATE or COPY fail if the newly named object already exists.
Y
The pre-existing object is replaced by the copied or renamed object. The warning message EQQI144W is issued.
Note: This works only when the Batch Loader statements refer to an individual object. If wildcards are used in the batch loader key fields, or USELIST is used, the command fails if the newly named object already exists. In these instances additional Workload Automation Programming Language commands must first delete the destination objects.
