RSIDs may be missing when any one of the following conditions is true in at least one of the documents that is being compared or merged:
At least one of the documents has been edited and saved in an earlier version of Microsoft Word.
At least one of the documents has been saved as Web Page (*.htm; *.html) or as Web Page, Filtered (*.htm; *.html).

On the Tools menu, click Options.
Click the Security tab, and then make sure that the Store random number to improve merge accuracy check box is selected.
Click OK to close the Options dialog box.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Office XP Service Pack 3.
When you compare and merge documents, Word uses randomly generated numbers (RSIDs) to track related documents. Although these numbers are hidden, they may be used to demonstrate that two documents are related. Word may fail to merge any existing revisions to a document when the RSIDs for a document are missing.
