Sum totals on subforms disappear
Posted on 2014-02-10
I have an Access 2010 ade which normally works fine but we have instances where the Sum totals on forms are blank. This is typically totals of data in subforms displayed in footer. Control source of text box =Sum([Field1]) or I often use =Nz(Sum([Field1]),0). In some cases you can go to the form and click on field or move between tabs and they will display although erratic and seems to get worse over time. I have researched this and seems to happen occasionally and can be fixed by rebooting the PC.
In this case we have just moved to a hosted terminal services environment where it is not so easy to reboot the PC when there is an issue. There are several users using the program on the same terminal services box (separate copies of ade but using the same MSACCESS.EXE) and if one user gets the issue seems to spread. First happened in Mid Jan - we restarted terminal services server and all OK - Happened yesterday and restarted overnight and all OK now.
However this is an issue as not easy to restart terminal services server during the day as all users logged on - issue effects quite a few forms - I could write some code to put total in an unbound textbox but there are a lot of these to do and hoping for an easier solution.
I am hoping someone else has had this happen and has found out the cause of the issue.
Appreciate any help.
