ELI5 How to use FlowFields

[@MuhammadIsrar-w5v]

How we can define flowfield on the basis of ENUM field? i.e. FieldClass = FlowField; CalcFormula = exist("Comment Line" where("Table Name" = const(Database::"XYZ"), "No." = field(Code))); As, it shows warning message: An implicit conversion is being performed from a value of type 'Integer' to a value of type 'Enum Microsoft.Foundation.Comment."Comment Line Table Name"'. This conversion can lead to unexpected runtime issues. Is there a way of doing this? Its not working.

you need to define enum value, not table number: CalcFormula = exist("Comment Line" where("Table Name" = const("Comment Line Table Name"::Item)));

​@@ProfMaravic thanks for helping, I have tried your suggested way, but results are still not as they should needs to be. As, There are lines available in Commet Line tabe with above filters (in calc formula); But on page where I have use this FlowFleld it shows me "No" - (there is no such comment line) instead of "Yes" - (there is/are such comment lines/lines)
