Automatic Assignment of Physical-Sample Drawing 
Use
Whenever an inspection lot is created for a goods receipt for which physical samples have been planned, the system automatically assigns a physical-sample drawing number to the inspection lot.
The physical-sample drawing number is referenced in all physical-sample records for primary, pooled, and reserve samples. This allows you to identify the origin of and relationship between all physical samples drawn together from the same inspection lot (for example, to determine which pooled and primary samples belong to the same physical-sample drawing).

The system also creates a physical-sample drawing for an inspection lot in which no physical samples were planned. You can use the corresponding physical-sample drawing number for such an inspection lot, to create and process physical samples manually. For more information about unplanned physical samples, see
