Maintaining Products

Overview

A product defines the specifications that need to be achieved for a material.

A sample may have a product code attached to it, such that, when results are entered for the sample, either by being captured from an instrument or entered manually, product analyte limits are checked to ensure the results are within the defined range, and any product rules that exist for the product code are activated. These product rules include sample type validation or calculations, and can be used to check sample results against pre-defined conditions and logical rules.

This process is pertinent to laboratory and QC managers who configure the analytical environment for the laboratory, especially with regard to products and production requirements for product targets.

Process

Products are maintained using the Method application. You need specific rights to have visibility to this application.

Products are maintained using simple SCRUD (search, create, review, update, delete) functionality under the Methods » Product codes node. You need specific rights to have visibility to this node.

Maintain products

Products contain analytes for particular scheme versions to hold the product specification. The limits applied to those analytes denote the product specification.

Maintain analytes for a product

Where a product code is attached to an unknown sample, for those analytes registered on the sample, the product analyte limits apply to the results. Where an unknown sample is linked to a product, when a numeric result is assessed against the product, it is assessed as follows:

  • If the result <= Lower action limit, or the result >= Upper action limit, then the result fails against the product for that analyte.
  • If the result <= Lower warning limit, or the result >= Upper warning limit, then the result passes against the product, with warning, for that analyte.
  • Otherwise, the result passes against the product for that analyte.

Products contain rules that comprise custom script that is executed when a sample that is linked to the product receives a result. A product rule is linked to a scheme so that the script is executed only for results captured for that scheme.

Maintain rules for a product

Product rules contain VBScript, and are stored in the PRODUCT_RULE table in the CCLAS database.

The ProductScreenn PRODUCT program settings define the custom forms that are launched from the Run main menu option, which is only available where the user has access to the Product codes node.
