Searching through block [message #614260]

I need to check each row as the user enters that it is not a duplicate. I plan on checking after when-validate-record or when-validate-item. It will not let me move to a new row using first_record and next-record because this navigation is not allowed. I don't want to write a cursor against the DB because not all the rows have been stored yet. How can I cycle through the block and compare each row to the current row? Thanks in advance.

Use the post command to write each record to the DB as it is entered. Then use a cursor, or select statement in when-validate-record.
Post writes the data to the DB but does not commit it, so if the user doesn't want to save the changes those modifications can be rolled back.

Can you please suggest a trigger to put the post command in. I have tried a few and keep getting errors that it is not allowed.

You may want to wrap it in an IF statement that checks the block_status.
