Field help (SALSAUSTU) 

This is the conversion factor between the sales unit and the stock unit. This coefficient can be modified. It will be modifiable if the sales unit of the product or the packing unit have been checked as 'modifiable' (see the Product record). It cannot be modified if the unit used is a unit defined for the customer. If for the units used, the factor is modifiable, it is necessary to define only prices expressed in stock unit.

Once the line entered, it is no longer possible to modify the conversion factor. It is necessary to delete the line and recreate it to modify this factor.

Specificities linked to the inter-company: if the order has been generated from inter-company or inter-site sales order, this information is initialized with the factor calculated between the purchase quantity and the stock unit and it cannot be accessed. Only a modification of the original purchase order can modify this information.
