In my Purchase requisition workflow I added a conditional decision for the field "Approval amount". Usually when you add a field that contains an amount, when you set the cursor into the field to enter the value, a second field is shown to enter the currency. This works for example for the net amount field on the purchase requisistion line. For the approval amount the currency field is missing. Approval amount is not a table field on PurchRerqTable. Nevertheless in another AX System (AX2012 R3) of the same customer, currency field for approval amount is there.
