Error while changing Phys Invt Counting Period Code value

Hi Friends,

Version: 2009

In item card, Warehouse tab:

I am trying to change the Phys Invt Counting Period Code from A to B and I am getting an error The date is not valid when Last Counting Period Update field contains some date value. If Last Counting Period Update is 0D, then I could able to change Phys Invt Counting Period Code field.

May I know why this is happening? Can any one give solutions?

Thanks, Aarvi.
