Reproducing the Issue

Steps to reproduce may vary as per the custom implementation done by you.

Example steps to reproduce -

  • Login to frontend system with the user X.
  • Open custom workcentre view.
  • Click on New MDR.
  • Schedule MDR.
  • At the same time login with the user Y and schedule the same MDR.
  • MDR schedule fails with the error message Cancelled manually or by the system.



When two MDRO jobs are scheduled at the same time, one of them will acquire a lock for the MDRO and the BO. Since, the second job cannot acquire a lock it will fail with the message “Cancelled manually or by the system”.


There is no option for the same MDRO to execute simultaneously.

If you want the second job to execute after the first job finishes, there is an option ("schedule after job") and it can be done on the UI.
