Hi ARTmaslen_AZ,
It seems you've already checked your user access, and since both you and the other user have administrator rights, the issue doesn’t appear to be permission-related. Typically, only the Administrator or Owner can add inventory codes, but since your access is correct, I recommend clearing the AccountRight cache. This can help resolve any software discrepancies that may be causing the items list to be in "READ ONLY" mode.
If the issue persists, it would be best to contact our support team for further assistance. You can start by reaching out to our virtual assistant, MOCA, at myob.com/support. If MOCA can't resolve the issue, it will transfer you to a live chat agent for more detailed help.
Regards,
Earl
