Activity Hook Error: Activity EJB does not implement hookable interface

[Former Member]

Hi everyone!

In "Operation Maintenance" I added the activity hook "SU570 - WIP Change " to the POST_START activity. On starting a respective SFC I receive the following error message:

"Activity 'SU570' ist an EJB ('Change Configuration'') and it does not implement the hookable interface (Message 16014)"

Can anyone tell me whether this error is due to misconfiguration or actually an implementation error?

Thanks & Regards,

Jule

Juliane,

Usually hookable activity has "Class/Program" option set to "EJB" or "Java class", in Activity Maintenance. Please try both.

If no luck, then try to assign the hook at another hook point e.g. PRE_START or PRE_BATCH_START.

If not working in any case, then it's probably a bug.

Hi Sergiy, Hi Mike!

Thanks for your answers, they were both very helpful.

Actually the proposed solution of setting the activity type to "Java class" solved the problem. And hinting that SU570-Hook is for internal use was helpful too as we were simply testing around a bit with activity hooks and unaware of hooks existing rather for internal use.

Thanks.

Although the online help states that SU570 can be assigned to hook points, per code it is not a hookable activity.

SU570 is not suitable for use at a hook point. It is used internally by SAP ME.

The list of Hook Activities can be found in the online help:
