Configure 'Requested Quantity' attribute

As an implementer, I want the option to include and configure the "requested quantity" (J) attribute (Requested override of calculated quantity.This is quantified in dispensing units.) in the requisition template so that storeroom managers can access the appropriate template to request the exact quantities they need to serve their patient populations.

Acceptance Criteria
Verify that:

• 'requested quantity' is associated with a template by program (templates are associated by program)

• "requested quantity" is available on the requisition form for the appropriate program/facility

• "requested quantity" column is NOT displayed/available on the requisition form when not associated with a template/program

• "requested quantity" source is user input (only non-negative and integer are allowed)
  data entry validation: If the 'requested quantity' value is different than the "calculated order quantity" (I) then a requested quantity explanation (W) is required (see the attached screenshot)

• the attribute is displayed in the template defined order on the form

• only non-negative and integers are allowed
  (J) overrides (I), meaning that any calculations, for example the total RnR cost, should use the quantity entered in J over I when data is entered in both

• appropriate permissions are enforced

• data validations should match 2.0 functionality

Additional note: please view the configuration requisition template attached to the epic to see the interconnection with other requisition attributes.
