Dear Expert,
My Client is totally customised implementation, Order created by HBS0 & followed by VA02 & VA03.
Order cancelled by a Z T-code, now if once Sales Order has been cancelled then no subsequent documents should be created. But unfortunately allow to create in my system.
We want to restrict to create subsequent document Like Debit/Credit note by VA01.
Would you please suggest me which USEREXIT or BTE can apply with VA01 to restrict DR/CR note.
To identify Cancelled Sales Order by Delivery block, Sales Unit & Business Entity empty.
Debit Note Process,
VA01 choose notes YDN or YCN press Enter choose Sales Order then Enter new message should be appear if sales order is cancelled, ERROR message should be appear as Sales Order Already Cancelled.
