PERSON EIT INFORMATION VALIDATION RULE

We have a requirement to have custom table to store some Benefit plan details for some employees,. We have planned to store in 'PERSON EIT' INFORMATION.' The EIT contains two flex fields ,

1. International benefits
2. Dependent details

In 'international benefits' we have three segments

1. Plan name
2. .Plan Member ID
3. Covered Dependents

In' Dependent Details' we have

1. Plan name
2. dependent type (Spouse/child)
3. Plan member ID

In this case, we would want to add dependent details based on the 'Covered Dependent' field. Eg., If value given in covered dependent is "2" only 2 records can be added in 'Dependent details' , we cannot add more than 2 .
