Add additional Demand in a custom measure within Supply Planning

Summary:

Custom measure to add weekly demand in Supply planning

Content (please ensure you mask any confidential information):

We have a client requirement where users need the ability to enter additional demand for a set of items (Having inconsistent demand) on a weekly basis directly in supply planning.

Currently, the Demand plan is maintained on a monthly basis, which creates a gap for capturing short-term demand adjustments. We would like to explore whether a custom measure can be configured within the supply plan to allow users to input this weekly value, and for the Total Demand calculation to incorporate it during planning supplies.
