Question related to Sales update

Hi JDE Distribution Team,

I have a situation related to one sales order.

This sales order has two lines 1 and 2

Both these lines were invoiced and had the invoice number(DOC), Invoice type(DCT- RI), Invoice company(KCO) populated when the invoice program was executed.

After that, one user manually changed the status of the order, all lines to Pre-invoicing status.

Then the DCT, KCO fields were blanked out only on line 2. But the line 1 DCT, KCO remained in tact.

I expected the line 1 with Document type DCT(RI) to have gone through the sales update instead of line with Blank DCT.
