IDR Issue on identifying LE, Supplier, and PO Number

Summary:

Content (required):

Ok. One PDF is having Legal Entity value as "ABC DEF LLC" but our Oracle has value "Abc Def Group LLC" It is somehow picking the keyword "DEF LLC" and treating this value as a Supplier "Def LLC". Do you know how can we make sure that in next set of PDF, we can treat this as a Legal Entity "Abc Def Group LLC"?

We also have "PO Box 12345" which is part of the Address but it is getting picked as a PO Number 12345. How to make sure that this is not getting picked as PO Number?
