Validations to avoid line items with duplicate value of CBS code or unique field
Hi,
As unique field configuration is not available for detail field form, is there any way to put the validations to avoid line item creation with duplicate value of CBS code or any field which we want unique per line item?
e.g. We have activity ID field in line item and if we 10 line items (manually/Integration) then all 10 line items should have unique values for Activity ID.
