I am using an activity to delete some instances in Database table.
I am using Obj-Browse and Then Obj-Delete.

This works in Dev Enviororment perfectly.

but in Pre production env it doesn not works

I am getting a below error

"Save, Delete or Commit has failed because lock "ERIC-FW-BPMSFW-DATA-CRAPPROVALDEFINITION AIRCEL997" is not held"

Now the instace in not an work object its simple row which contains some details. Work objects are not associated with this.

Cant understand why the same code is working in Devlopment env but not in Pre PRoduction env.
