Oops, looks like I jumped to a conclusion without having enough info.

Prior versions of MRP did have a number of different problems. DBA Tech Support has been working on it since at least last December. They sent me several "fixes" some of which were worse than the original problem. But, I have tested the latest files (emailed directly to me by DBA and dated 6/24/03) quite a bit in a test company and now have them installed in our live data. For us, they seem to work well. Your mileage may vary.
Juan, I am sending you the files. If anyone else is interested, contact me for a copy. cpappas@industrialdata.com
