Web Dynpro application callable object error: Page Builder Not available

Question

Hi, SDN Fellow.
I created a callable object of Web Dynpro application. The callable object is atatched to an Action, and Action --> Block, and Block --> Process.
I initiate the process in GP Runtime, when it comes to the Action screen the Web Dynpro application atatched to, I got the following error:
The page builder required to display this application UI inside the portal environment is not available.
As aa comparison, another callable object that atatched to a Web Dynpro component (that implement GP interface) is working fine.
Please advise.
Thanks in advance,
KC

Hi KC,
When you start your process from GP Runtime, does the actual action/callable object open in a new window?
Have a look at this SAP Note:
[Error when executing a GP task - Page builder|https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes/sdn_oss_bc_gp/~form/handler%7b5f4150503d3030323030363832353030303030303031393732265f4556454e543d444953504c4159265f4e4e554d3d393831353137%7d]
Although the error message you are getting is different, but if your callable object opens in a new window, then the problem (in most probability) is the same as mentioned in the SAP Note.
Also, try testing the Web Dynpro callable object in standalone mode. For more information on this, see:
