SAP Work Manager 6.3 Error - "Problem in BAPI create (/SMERP/PM_DOWORKORDER_UPD)"

Hi,

We are using Out-of-box SAP Work Manager 6.3 on SMP-3.0 SP-10.

I Edit a Work Order, put some comments in Notes field and Transmit, then I am getting below error in SMP Log -

2016 04 16 12:32:20#+0100#ERROR#com.sap.mobile.platform.server.agentry.console###Agentry com.syclo.zWorkManager.SNote Worker Thread#########Exception: 12:32:20 04/16/2016 : 20 (Agentry3), Java Business Logic Error (com.syclo.agentry.BusinessLogicException: WorkOrderPostSteplet - Problem in BAPI Create (/SMERP/PM_DOWORKORDER_UPD):while trying to invoke the method java.lang.Object.toString() of a null object loaded from local variable 'element'),  |

Also getting this error, when doing TRANSMIT after making a simple change, like added an operation or setting the status.

Please note, for some fields (like Description) I am able to make changes and Transmit successfully.

Please let me know, if you need more information.

Regards,

Divya Mehta
