BIX error writing DDL:"table cannot be more than 30 characters"

SA-38120

Summary



User has recently upgraded from PRPC 6.1 SP2 to Pega 7.2. They have upgraded BIX at the same time and this is running successfully in production.

A requirement has come to add some new properties to our BIX extracts and when trying to create the DDL script for this it is failing stating that a table name is too long, however, this is an existing table name that was being written to in the older version of BIX and is being written to in Pega 7.2.

Steps to Reproduce



Add new property to BIX extract and run command line extract to create a DDL file.


Root Cause



This is an expected behavior. PRPC restricts the table length to maximum 30 characters.

Resolution



Explained as it is expected behavior.

Also, explained an alternative local-change to re-name the tables and use the same table name (of length < 30 characters) in BIX extract rule.
