Have you solved this issue already?. Regarding Screenshot at 1.09.44pm, shows an error that I understand and I might be able to help you with. Screenshot at 1.10.48pm not sure if it is a database trigger or table trigger issue. Also, if this is an Oracle Forms trigger I' might not be able to help you out since I'm not an Oracle Forms developer. But I can be helpful if it is a database or table trigger issue. In regards to Screenshot at 1.10.58pm, it is also an error that I understand and I might be able to help you with. Not sure how long this issue will take me to look into it, 14 days is an estimate. Best regards.
