Reading this article you will learn:

  • The basics of the Object Value Selector (OVS)
  • Advantages of the OVS over traditional search helps
  • Steps required to add OVS help in HCM Web Dynpro applications

 

Key Concept

The Object Value Selector (OVS), unlike other Web Dynpro search help options, adds a friendly search help allowing users to search for values based on criteria involving multiple field values.  

Web Dynpro is a technology used by HCM developers for the development of applications. While developing HR Web Dynpro ABAP (WDA) applications, you may be required to provide a custom search help for searching using one or more fields or for populating multiple fields such as IDs and Description. One of the ways of doing this is with an Object Value Selector (OVS).

In this case, a search help may provide a number of field values from a given table or a number of tables. I show how to program the OVS to make search helps. After showing the advantage of using an OVS, I then discuss the technicalities involved, such as the different phases of selection and the steps in programming an OVS in Web Dynpro. Finally, you see a full-fledged working example with coding and illustrations. The example shows an input help for an Employee Number field for fetching the number and naming a list of employees.
