Why recalculateFormulas is not working on the relationship fields?

Hi Mohit,

recalculateFormulas()

Recalculates all formula fields on an sObject, and sets updated field values. Rather than inserting or updating objects each time you want to test changes to your formula logic, call this method and inspect your new field values. Then make further logic changes as needed.

NOTE: This method doesn’t recalculate cross-object formulas. If you call this method on objects that have both cross-object and non-cross-object formula fields, only the non-cross-object formula fields are recalculated.

Cross-object formulas are formulas that span two related objects and reference merge fields on those objects. Cross-object formulas can reference merge fields from a master (“parent”) object if an object is on the detail side of a master-detail relationship. Cross-object formulas also work with lookup relationships.

Hope this helps you.

Thanks
