Hi
I'm getting errors when trying to join two fields in one table to two fields in another table... "Invalid expression. Parsing of expression for the business object', etc... "has a different cardinality than the detected cardinality".
I joined the fields--> tables externally by dragging the field name in one table to the other table.
even I tried this too, selected on link externally table1.field to table2.field, then right click to edit the join. Once in the editor click and control click the fields in table 1 to select, the click and control click the fields in table2. still it's throwing error: Invalid Expression. Parsing of expression for the business object. Cardinality also not detected.
