There are two types of flexfields: key flexfields and descriptive flexfields.A key flexfield appears on your form as a normal text field with an appropriate prompt.For example, if a subfunction corresponds to a form procedure not associated with a graphical element, its availability is not obvious to the form's user.
In the Oracle Applications, only the Accounting Flexfield uses segment qualifiers.
You can think of a segment qualifier as an ”identification tag” for a value.
It does not guarantee that there will be no operating system errors when you attempt to use the file handle.
This procedure reads a line of text from the open file identified by the file handle and places the text in the output buffer parameter.
Cross–validation is different from segment validation, which controls the values you can enter for a particular segment.
