Purchasing: Regular Vendor at Client Level
Description
As of Release 3.0, there is a new indicator in the purchasing info record that allows you to specify a certain vendor as the "regular vendor" for the material at the organizational level "client" (i.e. for the entire corporate group).
This function is comparable to that of the "fixed vendor". To date, it has been possible to specify the latter in the source list for the lower organizational level "plant".
The indicator "Regular vendor" will be especially useful in retailing and commerce, since selling prices are frequently calculated at "client" level for the entire corporate group (i.e. for a group of plants, or distribution channel).
Changes to the interface
There is a new indicator "Regular vendor" in the "Supply option" area of the purchasing info record.
Change system parameters in customizing
In the standard system, the "regular vendor" is not treated as "preferred"
in source determination: instead, it has the same status as other sources of
supply.
If you want the system to suggest the "regular vendor" during the source
determination process, the indicator "Take regular vendor into account" must
be set in Customizing.

Set
up regular vendor.
The corresponding field in the purchasing info record is the new field "Regular vendor", which you can use to identify certain vendors.
Dependent functions
If you wish to work with the source determination facility for purchasing documents, unless you want to use the regular vendor at client level in the same way as the fixed vendor at plant level it makes sense not to maintain a "regular vendor", so that the system suggests all existing sources, not only the latter.
Further notes
If you wish to enter a different vendor than the regular vendor in the source list or quota arrangement, the system will issue a warning message.
For the purchase requisition and purchasing documents other than RFQs you can choose whether the system message is to be a warning or an error message.
