Performance issue specifically while calculating the Line Cost.
In the Create Requisition application, after entering both Quantity and Unit Cost fields it can take a few seconds to the system to calculate the Line Cost.
Resolving the problem:
1. Go to the System Properties application.
2. Bring up the property mxe.webclient.ClientEventQueue.threshold and set its Global Value = 1.
4. Select the property and click on Live Refresh.
5. Sign out of Maximo and sign in again.
Note: That system property description says "The maximum number of events that can be in the client event queue before being sent to the server.".
