Is there any custom function in expression builder in report definition?
Please let me know how to achieve this?
@UadayTarun please could you check a similar question 'PRPC 7.1.9 Expression Builder using functions" posted on the forum?
Also see “Pega 7.2.1 expression builder showing limited libraries/ functions”
It would appear to answer your question too. The main documentation can be found here and here.
If this does not give you the information you are after could you provide a screenshot and example?
