Change field flags

Click on the down-arrow at the far right of a flag-column, and you will see this dialog box:

All fields has so-called field flags among their attributes. In Lotus Notes, these flags control different field behaviour. List Fields let you set or un-set the following flags:

• Summary. As you may know, Lotus Notes saves the data separate from the presentation. List Fields looks at the document data without using a form, and thus looks at the back-end data of the document.
  
  In order to be able to show the document data in views, Lotus Notes must copy that data to a special memory buffer, the summary buffer. This means that only items that have the Summary-flag set can be shown in views. The Summary-flag also controls whether a field can be used in @Formulas etc.
  
  Richtext fields cannot have the Summary-flag set, and thus can't be shown in views.
  
  You can use this flag to optimize space-usage in databases, if you know that a field won't be shown in views or used in formulas.
  
• Sign. The item is signed
• Names. The item contain names. Note that Readers and Authors flags cannot be set unless you also set the Names flag
• Readers. The item contain reader names, and thus participate in controlling the read-access to the document. You can have multiple reader and/or author fields controlling access to a document, and the real access to the document is a union of all such fields. You can check out your real database- and document access in the Access-pane in the Information Area.
  
  The content of a reader-field can be combinations of individual user names, server names, group names, and access roles. Remember that roles always are enclosed in square brackets, such as [Group Name] and that names always must use fully canonical names such as CN=Jon Done/O=ACME.
  
  The presence of a Readers-flag implies presence of a Names-flag.
• Authors. The item contain author names, and thus participate in controlling the write-access to the document. Just as for the Readers-fields, multiple authors-fields may exist, and your real access is effectively a union of all author-fields.
  
  The naming rules of the readers-field also apply to authors-fields.
  
  The presence of a Authors-flag implies presence of a Names-flag.
