Hello 

1. For “External transportation lead time” in matrix, where it can be impacted on? please help to clarify as when I change this value no impact on purchase order’s planned delivery date or planned arrival date. 
2. For “transport lead time”, in Help mention that it is counted in working days of external transport calendar, where this calendar to set up, if not set up, which date it will be counted. Please help to clarify. 

Thanks

Susan
