In Collection Management, when the Supervisor is assigning open items to the Collection Specialist - the Collection Specialist's name is getting changed in the open items.

For Example - There is a Business Partner '12345' having one open item. The same open item has been assigned to Collection Specialist 'XYZ'.

After some time it is been observed that the same open item gets reassigned to different Collection Specialist 'ABC' automatically.

Please help in this matter.
