Sometimes, the "search by" parameters aren't enough to find what you're looking for. Here are some tips to find what you need.
As an example, let's look at the Accounts Payable (A/P) Bill List screen. Let's say we want to search by Purchase Order (P/O) Receive #. Under the Search by drop down, this is not an option.
Don't be discouraged. Click on More Filter to open the Filter menu. Scroll down to Receive # and enter in the specific number you are looking for. Click Apply.
This will return the values you are looking for.
