Using same Ext Doc No twice on sales invoicing

Smashed_Pumpkin

Hi all,

Is it possible to use the same External Document Number twice when doing sales order invoicing? At the moment the number can be used multiple times when doing shipping, but only once on invoicing.

Thanks in advance.

Only when it's on two different Vendors.

Anything else doesn't make sense! Not to me at least!

Receiving two different invoices from a vendor with the same invoice no. doesn't seem logical.

Edit---->

Never mind. I overlooked the fact that you were talking about sales invoices. Not purchase invoices
