two tables table1 and table2.
a layout based on TO table1 with table2 related through table1::global_Selector<-->table2::Key
a portal based on TO table2 on this layout
a filter in table1: table1::global_Filter
a calculation field in table2 to be filtered: table2::calc_Value
No relationship is based on the calculation field
records of table2 show nicely in portal with no portal filter
records show with filtering calculation based on table2::calc_Value when calc field is STORED
no records show with filtering calculation based on table2_calc_Value when calc field is UNSTORED
Can unstored calculation fields be used for portal filtering?
