问题
I am exposing some Pages in Navision 2009 as web services. To update a record, you have to issue a Read request, and send the Key field along with your Update request.
I would rather calculate the Key myself for 2 reasons:
- Using the filters in the read request is awkward - a sql query would fit on one line.
- Performance is terrible.
I've been able to figure out that at least part of the key is a Base64 encoded string of the columns that make up the primary key. I hope that someone can tell me where to look (database, code base, docs, etc) to tell me how the Key is calculated.

Sorry, I don't know how to calculate the key. Instead of calculating the key, have you considered doing your data manipulation in a codeunit instead, and exposing that codeunit as a webservice?
