Not a problem and thank you for the quick response. To replicate the issue, in the accounting module add a new vendor. Put the first name as Sales and the second name as Person. Call the company Test.
Next go to Accounting > Transactions > Purchasing
Click New Transaction > Create New Purchase (As a side question I am assuming this means requisition – a fair assumption?) or New Purchase Order and the blank form pops up.
Select the dropdown for Vendor* and you will see that instead of the company name Test, it shows the first and last name, in the test example – Sales Person. The expectation would be that the company is the vendor.
Please let me know if this helps or if more questions. As another aside so that I know when submitting, what is the wait time before I can submit another post? 60 minutes? I assume you have the time out built-in for security purposes.
