HWC Facilities and Inventory linking for Prescription and Pharmacy management

Existing configuration:

Need to investigate and understand the existing configuration for mapping HWC facility (HWC store) to manage the stock (medicines), i.e. 
1. mapping medicines to facility
2. get medicines for Prescription

3. get medicines for Pharmacy

Need to check in HWC Application for impact after New facility hierarchy mapping and facility creation.

In existing HWC Application, "facility_id" is used to get form Store creation and mapping under Inventory module, as follows:
Facility Type Master >> Main Store & Sub Store >> form here “facility_id” is created.

and in "Item to Store Mapping" stock (medicines) is mapped to Store.

Changes Required:
According to new concept of Facilities based on hierarchy, need to map Inventory module accordingly.

Migrate / change "Item to Store Mapping" to "Item to Facility Mapping"

Medicines >>Facility >> Role mapping is required
