In Quik Reports for Windows, the fields that are available for linking are indicated by green arrowheads. This means that those fields are indexed, a requirement for creating proper links. If the field you want to link TO does not have a green arrowhead, that means the link cannot be created.

You do not have to link FROM an indexed field with a green arrowhead; pretty much any text field is OK.

From what I can see, you are tring to link documents in Order History to those in AR Current Transactions. If you cannot link to the Full Document Number field (from AR Current Trans) because the field information does not match, there might be a way.

You have to link through the Customer Master file, and the link field is Customer Number. In your selection formula, you would need something link {OE History.Document Number} = {AR Current Trans.Document number}. This report would be very slow, due to the one-to-many link nature, but it could be possible.
