Service Item with double Serial Number in table Service Item

andy76

Hello,

I found that in our table Service Item there are a lot of service item having a double S/N.
I discover that for each couple, the first one is caused by posted sales shipment/sales order and the second one by the Sales Invoice (non the posted Sales Invoice).
I have seen this information in field Description 2.

I ask you if it is normal, an error, due to a setup or a bug and how solve that.

Thank you very much

To explain better in table 'Service Item' - 5940 there are two records having same "Serial No." but different key ("No.") and I think that this is not good.

This behavior seems to happen when using the function Sales Invoice - Get Shipment Lines and then register the invoice. Is that possible / normal?

Thank you
