Issue in changing Account Group of a Customer

Question

Dear Gurus,
I am trying to change the Account Group of a Sold to Party in XD07, from '0001' to 'Z001' (an exact copy of '0001'), but the system is giving an Error message "Change of account group not possible; customer used in SD documents".
          '0001' = Sold to Party
          'Z001' = Non Operative Customers (who are not dealing with us now)(Same number range, same fields / values)
I checked and made sure there are no open docs against his name and his account has Zero balance. The Customer is not having any Blocks. Still system is giving the Error message, now what to do?
Best Regards.

The groups indicated below are a few examples. There are many groups in Standard SAP & if we require additional Group, it can be copied from appropriate group & maintained.
Group | Name
0001 | Sold-to party
0002 | Goods recipient
0003 | Payer
0004 | Bill-to party
0005 | Prospective customer
0006 | Competitor
Select Sold-to-party  go to Details  Double Click on General data / Company code data / Sales data. It will take to next screen which details Tab Pages of General data / Company code data / Sales data. Double Click on Tab Page for example: Address, Control, Marketing & so on. Here you can maintain whether the field is to be Suppress, Req. Entry, Opt. entry or Display
