I am working on a telecom client who has a problem with manual condition type (E.g. ZDIS -- Class discount).
The business requirement is like this.
Value of order should be fetched automatically as well as manually.
The ZDIS are entered at the time of sales order or invoice.
But the problem is that ZDIS can be entered more then once in sales order or invoice.
I would like to restrict the condition type ZDIS to be entered more then once in sales order or invoice.
