I have created new table on "cm3rarea". Its appearing on the dbdict. While I am trying to search through db. I am find the table.
you need to create a format pointing to that dbdict as well.
I assume the message "Format or file not found" means in your case the format is missing.
I would create two formats: one with name "cm3rarea.g" as detail format and one with name "cm3rarea.qbe.g" as format for listing the records. Filename of format "cm3rarea.g" should be "cm3rarea".
Let me know if that solves the issue.
I suppose when you said that it is not present in the DB - you have checked it in the Database via db tools?
As I recall there were cases that it had to run synchonization or something like that to create corresponding table in the db. I would suggest to recheck it in some short time.
