We are in the process of partitioning some large tables because they soon will reach the limits for a single partition. In testing, we have a program that is writing a row/record (native RPG write) that should go to the third partition based on the range key. The write attempt is trying to put it into the first partition, and it is throwing a check constraint violation CPF502F: "Check constraint violation on member PART000001."

I would have expected the DB2 database manager would take care of ensuring the row was written to the correct partition. I can't find anything in the programming reference manuals addressing how to ensure that the row is written to the correct partition. Changing the programs to use SQL inserts rather than native language writes is not an option.

Any thoughts?
