How to search for a single PO number instead of multiple.
By default Purchase Order group is Optional and can be repeated - this option can't be modified.
This will cause several other instances of PO to appear as they are searched by the Language keyword.
In case you would like to bypass this please do the following
- Disable Purchase Order group in Document Definition Settings.
- Create your own Custom Group, you may add fields as well.
- Adjust it to your need and train.
This will allow you to receive fewer instances of so-called PO and train your own highly customizable group.
