Check the document fields for your project.
Avoid entering special characters such as < or > in your document or project fields. See Invalid characters in Document and Project Fields
Click the pencil icon in the Action column to make changes, such as making the field In Use or mandatory. Click the tick icon when you've finished editing.
Set a field as In Use to make a field available in your project. Change it to Not In Use it if you do not want to use it on your project. Some document fields must be included on every project. The In Use field cannot be changed for those fields.
It is not possible to edit a document field label or the help text directly. If you want to change either of these, please contact Oracle Support. For more flexibility, you may apply project fields or project field hierarchies to your document types.
You can check how your changes will appear to project participants by clicking the Preview button.
When you have confirmed that all document fields are correct for your project, and made any necessary changes, click Save in the top right hand corner.
