I am developing iviews using PDK. Like the R/3 system provide the help on perticular fields. How can I use the same help in my iview? Is there any method to display similar kind of help in an iview?
HTMLB doesn't support F4 help. The only more or less similar function is the date navigator help for input fields of type date, see http://help.sap.com/saphelp_nw04/helpdata/de/53/9d0e41a346ef6fe10000000a1550b0/frameset.htm (as well as under Tool Bar - Tool Bar Input Field).
On the other hand, Web Dynpro provides F4 help functionality, see for example https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/9214b1e5-0601-0010-fdb0-ec3... page 315 and more.
Hope it helps
