Working with Sealed Documents 4-13
You can use Oracle IRM fields see Section 6, Working With Oracle IRM Fields and
Watermarks to help reinforce the confidential nature of a Microsoft Excel
spreadsheet.
4.10.2 Linking Sealed Microsoft Excel Spreadsheets
Linking Microsoft Excel spreadsheets usually involves copying the contents of a cell in one spreadsheet and pasting it using Paste Special into the cell of another
spreadsheet. This means that any changes made to the cell in the first spreadsheet will be reflected in the second spreadsheet.
However, to protect the cell content of sealed spreadsheets, there are restrictions on the use of Copy and Paste Special between separately opened Microsoft Excel workbooks:
if you do not have copy rights Copy or Copy To, the content will be pasted as fixed text, and not as text that will be updated when the source workbook changes.
4.10.3 Updating Links Between Previously Unsealed Spreadsheets
Use the following procedure to update existing links in spreadsheets that were previously unsealed:
1.
Seal both the source and the destination spreadsheet files.
2.
Open the sealed destination spreadsheet file. You will see the Microsoft Excel message telling you that there are links to other
data sources.
3.
Only if you have already sealed the source spreadsheet file, accept the option to update the links.
You will see the Microsoft Excel message telling you that there are links that cannot be updated. This is because the file extensions have been changed from
.xls to .sxls.
4.
Accept the option to edit the links. You will see a list of links with the status Error: Source not found.
5.
Use the dialogs change source facility to search for the sealed source file with a .sxls extension.
6.
If prompted to, log in to the sealed source file. The links between the sealed spreadsheet files are re-established.
Caution: If you have existing unsealed spreadsheet files with links
between them, seal all the files before updating the links between them. If you seal only the destination spreadsheet and then try to
update the links to a pre-existing unsealed source, the links will be destroyed and will not be recoverable.
Rights: To open a sealed spreadsheet, you need the Open right. To
seal a spreadsheet, you need the Seal right. To see formulas on a sealed spreadsheet, you need the Formulae right. See
Section 1.3, About Rights
