Help with a simple calculation. I have a global field to calculate the current week of the year. This is the formula used - WeekOfYearFiscal ( Get ( CurrentDate ) ; 7 ). Every now and then when I open the app, this calculation is showing the wrong week. Today for instance it shows the week to be 40 when in fact it is 47. In the Data Viewer I copied the formula directly from the field and monitor it. It shows 47, but the field itself is not. I am sure it has something to do with how the field is storing or indexing or something but I can't figure it out. What would cause this?
