Limitations of Duplicate Detection Rule
- Duplicate Detection Rule Specification one can have only a rule with max match code of 450, which looks great only when the rule includes only strings or basic data types(like Integer, Money etc.), but the issue happens when a duplicate Detection rule carries at attribute of say an Option Set, it straight away consumes 255 of 450 match code length. Also a lookup field consumes more than 40 length. Which becomes really difficult to define one, because these data types don’t even support partial match, it has to be exact match.
- There is a limit of 5 published duplicate detection rules per entity
NOTES:
- TO disable Duplicate detection rule just go to settings and data management and select the rule and click UnPublish.
- Duplicate Detection rules cannot be included in solution so these rules are manually creates in all environment as we cannot move from one environment to other.
