This is a problem I have never seen before, I have a CRF that has 50 variables and 5 sections and it works fine. When I add 10 more variables a strange error occurs. The CRF presents fine in the preview but when I hit continue to add to the database all i get a list of failed insertions into the database, All 60 variables fail to install, The error messages doesn’t help either. The last 10 variables that caused this behaviour work fine alone as well as when combined with a smaller set of variables. Has anyone experienced this? Is there a maximum number of variables that you can have in a CRF?
The error message is: Errors were encountered while committing to the database. None of your changes
have been saved. Please review them and correct your data as necessary. You may
print this out for your reference. Please contact your administrator if you have
any questions. Please go back to the CRF List and submit
your speadsheet again.
I have attached the Excel sheet that cause this problem
