I have a db that I use to find matches for parts based on an external excel spreadsheet and a SQL database. This first pass finds all the parts with the exact same Manufacturer Part Number. The second pass finds all the CAP and RES matches based on part criteria. During the initial passes there will remain unmatched parts. I need to list the parts from the excel spreadsheet for which matches are not being found in the db. I have tried DISTINCT and <> and Not In but the list is evading me. The db is compressed and attached.
tblBOM are the parts from the external spreadsheet. tblMAX_MFG_PM are the parts from the SQL db. tbl_BOM has discrete fields. tblMAX_MFG_PM has mostly discrete fields except for the MPNDES_49 description field. MPNDES_49 gets broken out into its various fields using some excellent code from nutsch provided some time ago for another question.
