We're seeing that Business Central does not include the Blanket Order No. or Blanket Order Line No. on the Sales Credit Memo lines if you Correct/Cancel a Posted Sales Invoice.
On several occasions our sales teams has been left scratching their heads looking at the Qty Shipped/Qty Invoiced on a blanket wondering why it doesn't match their records of shipments. After looking into it, we discovered that accounting had made an error when invoicing, and corrected the invoice. But because the Blanket Order No. and Blanket Order Line No. were not included on the credit memo, the Qty Invoiced and Qty Shipped on the blanket order never got corrected. When accounting posted the corrected invoice, the blanket got decremented AGAIN because accounting had copied the previously posted invoice to create the new one, which does include the Blanket Order fields.
It seems that these fields need to be included on the Invoice Correction/Cancellation feature, so the system behaves as expected. Has anyone else run into this, and how did you handle it?
