<h1 class="topictitle1">Dependent file restrictions in check pending</h1>
<div><p>This topic outlines the restrictions that apply to an established
and enabled referential constraint in check pending.</p>
<p>A dependent file in a constraint relationship that is marked as check pending
cannot have any file input/output (I/O) operations performed on it. You must
correct the file mismatches between the dependent and parent files. Also,
you must take the relationship out of check pending before the system allows
any I/O operations. The system does not allow records to be read from such
a file because the user or application might not be aware of the check pending
status and the constraint violation.</p>
<p>To perform I/O operations on a dependent file with an enabled referential
constraint in check pending, you can first disable the constraint and then
perform the I/O operations that you want.</p>
