Thank you for your post.
Currently, I do not have access to a ESS table. I have been unsuccessful trying to replicate the issue using a related field in the Calculation formula. Regardless, I have sent your post to our Development and Testing departments for review. When I receive any feedback, I will let you know.
Our Testing department could not reproduce the issue using MySQL. Testing would like to know the ODBC data source and the ODBC driver and version being used. In addition, what is the field type being referenced in the ODBC source. Also, did this work previously with Windows 10 or a previous version?
Sorry for the delay of my reply.
I tested it with FM Pro 15 this week and it looks to be solved right now.
Still, version 14 still gives hard errors.
But with the renewal of 15, it is solved for me.
Thanks for your reply, TSGal.
