SAP QM 三种类型的Physical Sample

SAP QM模块里的Physical Samples management 功能在流程行业比如Pharma/Food/Chemical等行业比较常用的。

Following three types of physical samples are available:

     Primary samples   are taken directly from the population or inspection lot.

     Pooled samples   are created by pooling primary samples.

     Reserve samples   are primary samples that are reserved as specimen samples.

这三种不同样品的数量是由 sample drawing procedure来确定的。

那这三种Sample的定义和区别又是啥呢？见如下说明。

Scenario :  

Lets say I received a material from a vendor 100 L material supplied in two containers each 50 L.

Now I have to check this material . so I need to take samples from each container lets say I take 1 L from each container. so my primary samples will become two (each 1 L) as I take sample from each container. Primary samples are the ones directly taken from inspection lot qty.

Now the above two primary samples are mixed to make a pooled sample. In my example it will become 1+1 = 2 L. Pooled samples are created by mixing primary samples. these pooled sample is used for analysis.

Reserve samples are taken from lot directly and not used for immediate analysis. they are stored for future reference as per regulatory norms. Normally they are destroyed once the expiry of the material is reached. in our case let say 0.25 L taken separately and stored.
