We have a request by our benefits department to provide a list of all active Dependents that are also active Employees. I'm able to get a list of all dependents and have the values for SSN but when searching by SSN against the Employee business class it is taking about 10-15 minutes to search just one SSN record and we have about 20,000 records to search against. Is there a quicker solution via IPA that could provide this? i'm familiar with file loading but have never loading two different files and wonder if i had a flat file for dependents with SSN an flat file with Employees with SSN to match against if it would be faster with them both loaded into memory?
