Additional DSD Data: Material Data 
You can use this function to define DSD-specific material data in the material master record. You access the function from the DSD Data tab page and, if Vehicle Space Optimization is active, VSO Data and VSO Plant Data in the material master.
DSD-specific material data is integrated in the ERP material master.
In Customizing, you must activate the Direct Store Delivery backend and, if required, Vehicle Space Optimization. You can find these system settings in Customizing for Direct Store Delivery backend under Basic Functions.
For more information, see Implementation Considerations in Direct Store Delivery (Backend).
You need to assign the following screen sequences in Customizing for the system to display the tab pages containing the DSD-specific material data:
· Screen sequence BD for the DSD Data tab page
· Screen sequence BV for the following tab pages:
¡ DSD Data and
¡ VSO Data and
¡ VSO Plant Data
You will find the system settings for the screen sequences in Customizing under Logistics General ® Material Master ® Configuring the Material Master ® Assign Screen Sequences to User/Material Type/Transaction/Industry Sector
You can assign a DSD grouping to a material in the material master, on the DSD Data tab page.
By assigning a DSD calendar type to a DSD grouping, you can schedule appointments for visits and deliveries for each material. This means that materials with different DSD groupings and different calendar types can have different delivery cycles (for example, daily and weekly) in Visit Control.
You can maintain material-dependent data that will influence the Vehicle Space Optimization of a third party on the VSO Data and VSO Plant Data tab pages.
You can find the system settings for the material master for the Direct Store Delivery backend in Customizing under Material.
