Hi there Tino,
If you have a support contract between yourselves and the suppliers of the accounts package then I suggest that you check the agreement before you start making changes to the data dictionary or to the data in your database via the editor as doing so may invalidate certain areas (or all) of your contract.
What is it you are trying to do? Are you trying to export data from the database into Excel?
If this is the case you might want to see about contracting a Progress programmer for a few weeks or so as it sounds like you don't have one inhouse. The contractor will do all of the bespoke work that you need. This will also make sure that the code is correct for you. This will allow you to run the necessary programs when you need your data and you will not need to pay your suppliers any more unnecessary cash, although the cost of the programmer for the duration may be a little high you should weigh that cost against what you are paying your suppliers for the extra work!
HTH,
James.
