performance - as the purpose of buffers is to avoid unnecessary reads.

<DIV dir=ltr align=left><SPAN class=244485806-12042007><FONT face=Arial
color=#0000ff size=2>So you should not schedule SWU_OBUF or any other function
module that resets a buffer as that would have ***EXACTLY*** the same
performance degradation as SWU_OBUF. How bad that performance
degradation would be depends on many factors. I would not be comfortable
using your suggested approach in a production environment.

<DIV dir=ltr align=left><SPAN class=244485806-12042007><FONT face=Arial
color=#0000ff size=2>Instead SWU_OBUF should be run on an as needed basis
only - as per Chris Barr's excellent example - and remembering that
buffers are automatically refreshed at midnight system time anyway.

changes, and then manually execute SWU_OBUF. </FONT></SPAN></DIV>

around the use of SWU_OBUF. Does anyone know if the use of this refresh can have
any system performance issues? <o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial color=black size=2><SPAN lang=EN-CA
style="FONT-SIZE: 10pt; COLOR: windowtext; FONT-FAMILY: Arial">We are assigning
security roles to some task under the possible agent in order to restrict the
forwarding of these items… We also created the automation of this role
assignment when an employee gets the chief relationship or when he gets the
Substitute relationship. All this works fine but if I get the role assign now, I
don’t see it in the task ‘Display assigned Agent’ of the task until I refresh
the buffers.<o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial color=black size=2><SPAN lang=EN-CA
style="FONT-SIZE: 10pt; COLOR: windowtext; FONT-FAMILY: Arial">My solution is to
use function module RH_WF_OM_INDICES_TIMESTAMP_RFS (which is what SWU_OBUF does)
when the automatic role assignment is done… My fear is that it could reduce
system performance if it is done multiple times a
day.<o:p></o:p></SPAN></FONT></P>
