The physical samples created and processed in a stability study are identified by means of the following records:

• Stability study (quality notification no.)
• Physical-sample drawing number
• Individual physical-sample records

All physical samples processed in a stability study are associated with exactly one physical-sample drawing number, which is created automatically by the system when you create the initial sample. This physical-sample drawing number applies to all of the physical samples that are created and processed over the entire course of a stability study:

• Initial sample
• Stability samples (created for the various storage conditions)

All physical-sample records for the initial sample and stability samples reference the same physical-sample drawing number. The physical sample drawing in turn also references the associated stability study (quality notification number).
