# Advanced item sampling

The sample quantity can be configured in different ways in the **Item sampling** form (**Life Sciences Quality Control & Assurance > Setup > Quality control > Item sampling**):

- If the **Quantity specification** field is set to **Fixed unit**, the sample quantity required by the system will be equal to the quantity defined in the Value field.
- If the **Quantity specification** field is set to **Percent**, the sample quantity will be calculated as a percentage of the received/manufactured quantity.
- If the **Quantity specification** field is set to **Advanced**, the **Advanced** button is enabled. By clicking the **Advanced** button, authorized users can access the **Advanced item sampling** form, where they can define the sample quantity by analysis type. In the **Advanced item sampling** form:
  - The **Sampling quantity** on the header indicates the total quantity to be sampled. The total sample quantity can vary based on the total quantity received/produced or the number of sub-batches to be sampled.
  - The **Sampling quantity** in lines indicates the quantity to be sampled by analysis type (for example, 1 unit for physical and chemical analysis, 1 unit for microbiological analysis).

The Advanced item sampling is defined by filling in the following information:

- Header:
  - **Sub batches to sample**: the user can specify the number of sub-batches to sample.
  - **Total quantity**: the user can define the minimum total quantity required for the selected sampling.
  - **Sampling quantity**: the user can define the sampling quantity.
  - **Sample unit**: [sample unit](/life-sciences/docs/sample-unit) inherited from the **Sample unit** specified in the **Item sampling**
- Lines: multiple advanced item sampling lines can be created, following the order defined by the **Line number:**
  - **Line number**: automatically populated with sequential numbering.
  - **Analysis type**: the user can select the [analysis type](/life-sciences/docs/analysis-types) of the sample within the values defined in the **Analysis types** form (**Life Sciences Quality Control & Assurance > Setup > Quality control > Analysis types**). It is possible to divide the quantity for the same analysis type into multiple lines (that is, smaller samples) identified by different line numbers.
  - **Sampling quantity**: the user can define the sampling quantity of the sample.
  - **Sample unit**: [sample unit](/life-sciences/docs/sample-unit) inherited from the **Sample unit** specified in the **Item sampling**.
  - **Sub batch type**: the user can select the [sub batch type](/life-sciences/docs/sub-batch-type) to identify the type of sample (for example, **Retention**, **Identification**) within the values defined in the **Sub batch type** form (**Life Sciences Quality Control & Assurance > Setup > Sub batch > Sub batch types**).

### Example

Item sampling setup:

- The sub-batch sampling is set to sample all sub-batches.
- The advanced item sampling is set to:
  - 200 units (that is, 100 for microbiological testing and 100 for physicochemical testing) if 10 or less sub-batches are sampled.
  - 400 units (that is, 200 for microbiological testing and 200 for physicochemical testing) if more than 10 sub-batches are sampled.

#### Scenario #1:

- Four sub-batches of GMP material are received;
- A quality order is automatically generated when registering the quantity. The number of sub-batches to be sampled and the quantities by lab/analysis type are calculated.
- The quality order shows a quantity of 200 units; the number of sub-batches to be sampled is 4.
- The item sampling inquiry shows that 100 units are needed for microbiological testing, 100 for chemical testing.
- When lab analysts enter test results, the sample quantity for microbiological tests (for example, Bacteria) and for physicochemical tests are respectively 100.

#### Scenario #2:

- Twelve sub-batches of GMP material are received.
- A quality order is automatically generated when registering the quantity. The number of sub-batches to be sampled and the quantities by lab/analysis type are calculated.
- The quality order shows a quantity of 400 units; the number of sub-batches to be sampled is 12.
- The item sampling inquiry shows that 200 units are needed for microbiological testing, 200 for chemical testing.
- When lab analysts enter test results, the sample quantity for microbiological tests (for example, Bacteria) and for physicochemical tests are respectively 200.
