5. If medical program has funding_source = LOCAL , then invoke validation described at PreQualify Medication request request | 11.-Check-provision-for-a-programs

...

1. set:

   1. dispense_valid_from = created_at

   2. dispensed_valid_to = dispensed_valid_from + dispense_period

      data_patient_id,
      data_legal_entity_id

Update based_on

1. If the medication request request is based on activity with quantity - set remaining_quantity for the activity which was calculated at validation Create Medication Request: Validate based_on (p. 2.d.1 )
