Hi,
If I understand your question, you are looking for the note text from an item record. I can help with eEnterprise SQL server tables only, I am not familiar with Great Plains in other databases. I am also assuming that you are using Sales Order Processing (SOP).
In order to do this you will need to join the IV00101 to your Sales line table (SOP10200 for open and SOP30300 for history). Once you have done this link the SY03900 from your company database. You are looking for the NOTEINDX field in both the IV00101 and SY03900 tables for the link.
SOP30300 -> IV00101 on ITEMNMBR then IV00101->SY03900 on NOTEINDX
This should get the desired result.
