As OBP mentioned, without seeing the database it is very hard to come up with what is wrong.Originally Posted by Djblois
Can you make of copy of your database, re-create your Oracle WMS_PKO_HD table a s a native Jet (Access) table, and populate the tables with just enough bogus (non-sensitive) sample data so we can see how your form is interacting with the table? If that's reasonable, make a Zip archive file from it and upload the Zip here.
