Customized Appraisal Workflow doesn´t work from Workplace

[Garcia, Carlos]

Hi Colleagues,
 
We developed a customized appraisal workflow which works fine when you
execute the workitems from R/3 Workflow Inbox, but when you attempt to
execute the workitems from the Workplace (ESS) the appraisal =
information is
shown but the SAVE and COMPLETE buttons are missing.=20
 
The workflow could be triggered from ESS (service: MY_APPRAISALSM) or =
from
R/3,
it waits for the event "COMPLETEDAPPRAISAL" of the business object =
BUS7026.
The logic of the process
is the following:
 
1) The appraiser fill out the appraisal and press the COMPLETE button.
2) The workflow starts only if there is not a previous workflow related
   with that appraisal.
3) A workitem is sent to the chief of the appraiser in order to write
   comments about the appraisal, this workitem is based on a new method
   EDITASYN which combines the methods APPRAISALTAKEBACK and EDIT, also
   waits for the terminating event "COMPLETEDAPPRAISAL" (That is why we =
need
the
   COMPLETE button, which does not appear when the workitem is executed
   from ESS).
4) A workitem is sent to the appraiser in order to hold a meeting with
   the appraisee to review and comment about the appraisal. This
   workitem is also based in method EDITASYN.
5) Finally a workitem executed the method APPRAISALAPPROVE to change =
the
   appraisal status to AUTHORIZED.
 
We are on 4.6C and our patch level is the following:
COP  SAPKA46C27
COP  SAPKH46C27
COP  SAPKB46C27
COP  SAPKE46C43
 
The code of the method EDITASYN is the following:
BEGIN_METHOD EDITASYN CHANGING CONTAINER.

  ENDif.
END_METHOD.
 
 
Any advice or guidance will be very appreciated.
 
Best regards.
