Debit Notes in JDE

[daf1234]

Hi all

I have configured a sales order entry version for Debit Notes. With order type DM and line type DN ( non stock inventory interface)

Now my problem is
User is entering -ve quantity in the Quantity column on the debit note entry therefore this is going into my AR as a credit.
Is there a way this can be stopped. The system is already live on ERP 8.

User however does want to put use minimum order value hold, pls advise if anybody has other idea(s).

Thanks
