Here's an announcement on Unimatic Front Page News:

Effective Oct. 1, if a base ID contains one or more segments that require a qualified Purser, a qualified Purser must fill and work the qualified and non-qualified Purser positions for the entire id.

If you have an ID that falls into this category, please note that your FLTLOF and IBS will not indicate that a Purser-qualified flight attendant is required on the narrowbody segments. Programming changes are underway to correct these inaccuracies.
