I love the OAC product, but this one issue is very troublesome. When you do a data blend in the data tab of a workbook, you join related fields. However, if someone else does a different join on the same fields in another workbook, it breaks your joins and ruins your workbook. Plus, you have no idea who did it or which workbook it was done in. Vice versa, if you do a blend in your workbook, it breaks the joins in other people's workbooks. A data blend in one workbook should not impact a data blend in another workbook on the same dataset.
