Issue/Introduction

What is the recommended limit of number of units can be allowed at department OBS? Are there any known application performance issues if the department OBS units are large?

Environment

Release : All Supported

Component : CA PPM STUDIO

Resolution

1. In Classic Clarity, there is no limit to the OBS breadth (number of nodes per unit/level), but it can only go 10 levels deep, except in the Department OBS. See: How many OBS Levels can be created? for more details
2. In the New UX, there is one known limitation: Department OBS Is Blank in Cost Plan Detail of New UX if your departments exceed 50,000 due to a governor setting limit. 
3. There are limitations in XOG of OBS units as well: Unable to XOG output the OBS structure If the MAX_XML_NODES is not big enough the XOG output won't include the OBS structure.
4. If you are seeing any a performance issues the other thing that can cause issues is a slow running query on the DB end that the DBA can tune. See example at: OBS autosuggest feature is slow in Clarity
