How to avoid, that a CPD-Customer will used in Sales ORDER?

Question

Hi,
i will avoid, that the user inserts an CPD-Customer in sales orders.
It's only in quotation allowed.
Therefore i use include MV45AFZB with following code.
FORM USEREXIT_CHECK_VBAK USING US_DIALOG.
DATA: WA_KTOKD TYPE KTOKD.
IF VBAK-VBTYP <> 'B'.
  SELECT SINGLE KTOKD FROM KNA1 INTO WA_KTOKD
         WHERE KUNNR = VBAK-KUNNR.
  IF WA_KTOKD = 'CPD'.
    MESSAGE E010(ZZ) WITH
            'CPD-cutomer is not allowed!'.
    MOVE 'ENT1' to FCODE.
    EXIT.
  ENDIF.
ENDIF.
My problem is, that the user cannot chage the customer numer when error appears.
Is there another way to realize what i need, or is there a way to make the customer-Number
changeable in this case?
Hope anyone can help-
Regards, Dieter

Have you tried using order block?
Firstly define an order blocking reason for CPDs and assign it to all relevant order types in config.
SPRO/IMG/Sales and Distribution/Sales/Sales Documents/Define And Assign Reason For Blocking
And then block all CPD customers using VD05 ( there will not be many, so it shouldn't take time).
Alternately
make it a warning in the code you wrote and copy the same code as an error while saving the order using
MV45AFZZ - USEREXIT_SAVE_DOCUMENT_PREPARE or USEREXIT_SAVE_DOCUMENT
Hope this helps.
