Virtual attributes evaluation and performance

[Edward Diehl]

Why not test the critical value in a check function and loop until value it populated?  When populated exit the function.

Hi all,
 
I wanted to ask for you help with the issue in subject. I use virtual attribute quite often and it works OK. However I have one client where I suspect having performance issues with virtual attributes. Example: Simple approval workflow, agent is determined using a rule. Rule container if filled from BOR virtual attribute. Often the workflow goes into error for "Agent determination failed". I click "Restart after error" and now all works well. In addition, the problem only happens in production system. To me it feels like sometimes virtual attributes are not calculated immediately. This client posts many transactions every day but I believe SAP should know to handle it
I would also like to mention that the virtual attribute code is quite simple (no select statement or such).
 
Has anyone experienced something like this before? any recommendations? BTW, working with event queue handles this properly.
 
Thanks,
