In PeopleTools 8.50 adding a Rich Text Editor to Long fields was introduced. With this RTE users are able to actually format text like you would do in for example Microsoft Word. This was a great feature for online entry and presentation in PeopleSoft. Unfortunately this does have a downside. The text that is entered and formatted using RTE gets stored in the database as HTML. This means that when you are using PSQuery to query the data, the data is presented as plain text with the HTML tags and therefor also not usable in any BI Publisher reporting.
With PeopleTools 8.52 a new tempate is introduced that solves this issue and renders the HTML tags in the Long field to the actual formatting the same way as presented in online PeopleSoft.
