There are two possible reasons for corporate report section to be locked, the section is being worked on by another user or it or the section is linked to another editor question.
Section being worked on by another user
When accessing a section, you may be presented with a locked screen. If a section is locked, it means that another user is actively working on that section. A locked section cannot be edited. The section remains locked for other users until the initial user has left the section or logged out of the software.
Linked editor questions
Note: Only an administrator can Unlink a section.
After you access a section, you may be presented with a notice that the section has been Linked to another master section. This means that the content displayed in the response field is linked to content that has been submitted in another section.
When a section is linked to another section, you cannot edit the field in the current section. The Save function is disabled at the bottom of the screen. The content in the field is automatically updated if any edits are made to the content in the linked master section.
