Question -------- My formula does not work for a field (in the following example for field ‘numberC’) in my inbound formula. For demonstration purposes, I will use fields ‘numberA’, ‘numberB’, and ‘numberC’. PO1 POSITION 8 Line 50 Qualifier field mapped to ‘V’ PO1 POSITION 8 Line 51 Qualifier field mapped to ‘V’ PO1 POSITION 9 mapped to field ‘numberA’ Line 50 Formula: if |ELEMENT|[9] = ‘V’ THEN ‘A’ ELSE ‘B’ PO1 POSITION 9 mapped to field ‘numberB’ Line 51 Formula: if |ELEMENT|[9] = ‘V’ THEN ‘A’ ELSE ‘B’ PO1 POSITION 10 mapped to field ‘numberC’ Line 52 Formula: if |ELEMENT|[9] = ‘V’ THEN ‘A’ ELSE ‘B’ Answer ------ Even though you verify the prior |ELEMENT| in the formula, you must still map the prior position’s qualifier. Here is what you are missing: PO1 POSITION 8 Line 52 Qualifier field mapped to ‘V’ Here are some more tips for formulas: 1.Have you put appropriate brackets within your formula? 2.Have you generated your formulas? 3.Do you have other mapping references to that field that might overwrite this mapping?
