Field help (DACLIN)

Flag used to specify whether this element can be used in a price list structure (line structure).
This flag only concerns the elements of the amount type. Therefore it automatically takes the value No as soon as the element has been declared to be a rate.
As soon as this flag is set to Yes, the next field automatically takes the value No: in effect, an element cannot be used both at line level and at order footer or invoice level.
