Status does not allow you to change certain data

What causes this issue?

You have chosen a new status.

System Response

The system checks the status type of the new status in the IMG.
The document can have the status of status type S (lock status) or O
(original being processed) or L (enable lock field status).
If a document has a status with status type S or O, then not all fields
are available for entry. You can still carry out the following
functions:
Change the status
Link objects to the document
Change the deletion indicator (subject to authorization check)
If a document has a status type L, you can enable or disable fields of a
DIR (Document Info Record).
You enable or disable fields of a DIR in <LS>Maintain Lock Fields
</>work step in Customizing for <LS>Define Document Types </>under
<LS>Cross-Applications -> Document Management- >Control Data.</>

How to fix this error?

Before you can carry out a different function, you must first choose a
status that does not have status type S or O.
