Dear Frank,
on my Suspect_table I don't have master record with match_score = 0 and its rank = 'M'
In my case on my Suspect_table I have only two record :
First record has match_score = 85 and rank = 'M'
Second record has match_score = 85 and rank = 'S'
to create matching I have followed this article :
Modifying 'manually' first record with match_score = 0 the issue disappear.... regarding the link mention above where match_score has been put equal to zero considering rank equal to M ?
Best Regards,
MJ
