Assignment Key missing

Now-a-days, we are seeing lot of issues in our application where pxassignmentkey property of different kind of assignment is null on the clipboard.
I have gone through one of the article on PDN and found that pxassignmentkey is null on clipboard if corresponding entry for the assignment is not there in pc_assign_worklist or pc_assign_workbasket table.
But in our application, we are not deleting these assignments explicitely.
Could you please suggest what could be the probable reason for these asssignment keys automatically getting deleted from pc_assign_worklist or pc_assign_workbasket table?

Thanks in Advance

If I understand your explanation correctly, here is what I would suggest.

If the work object is 'Resolved' the corresponding assignment is removed from the PC_ASSIGN_WORKBASKET & PC_ASSIGN_WORKLIST by Pega.

If for any reason the corresponding Work Object is locked when the assignment is being updated to 'Resolved' then the Work Object will not be updated correctly.

You will have to write a custom activity to update the Work Object by ensuring that there is no assignement record in the PC_ASSIGN_WORKLIST or PC_ASSIGN_WORKBASKET tables.

Hope this helps.
