Which program is used to configure calendar settings?

The program specifically designed for configuring calendar settings is the System Calendar, Open (CRS900). This program allows users to define and maintain various calendar-related entries, such as setting working days, defining holiday schedules, and managing timeframes for different operational activities within the system.

Using the System Calendar, users can ensure that their warehousing and procurement processes align with operational realities, such as ensuring that scheduled activities do not fall on non-working days or holidays. Having an accurately configured calendar is essential for optimizing workflow and scheduling, which can significantly impact efficiency and productivity in inventory and order management.

Other programs mentioned, like Number Series (CRS165), are focused on the generation of sequential numbers for various system entries; User (MNS150) deals with user profiles and permissions; and Customer Order Toolbox (OIS300) pertains to customer order processing rather than calendar management. Thus, for the specific need of configuring calendar settings, System Calendar, Open (CRS900) is indeed the correct choice.
