table exists in multiple libraries.</li>

<li>An <span class="cmdname">OVRDBF</span> or <span class="cmdname">DLTOVR</span> command has

been issued. A file referred to in the statement now refers to a different

|
<li>An <span class="cmdname">OVRDBF</span> or <span class="cmdname">DLTOVR</span> command
|
||
|
|
has been issued, causing different override options, such as different SEQONLY
|
||
|
|
or WAITRCD values.</li>

<li>An error occurred when attempting to verify the statement override information
|
