Hi Lewisip, Thanks for the suggestion. Although all column names are different. I've actually just contacted Oracle Support and the problem was due to a property called Key Mode that needs to be set to Upadateable when the data block is based on two tables. This removes the ROWID column from...

Thanks for the recent reply to this one. Something springs to mind though. If I have a .fmx called AM01.fmx saved in the same directory as the form I'm using, and I have a trigger saying CALL_FORM('AM01.fmx'); shouldn't this open the form? At present I just get FRM-40010. If the forms are in...
