# Marketing Module Controls and Defaults (MRK.CONTROL)
Read Time: 1 minute(s)
The MRK.CONTROL procedure is used to define default information which will be used by the marketing entry procedures. The information entered in this procedure is loaded into the corresponding fields on new sales orders so that the same information does not have to be entered on every sales order. The user has the option of changing any of these defaults on the sales order after they are loaded.
Frequency of Use
The entries in this procedure must be loaded prior to using any of the other procedures in the Marketing Module. This is usually done as part of setting up the system. The entries may be changed after that time as required.
The finished goods and cost of goods sold locations must have been previously defined in the Inventory Location file ( INVLOC.E ).
