Exercise 4, Part 1: Creating Entity Types

Reference Material

Modeling Entity Classes and Types

Exercise Objectives

  • Part 1: Create two (2) new Entity Types in L7|Master

  • Part 2: Create two (2) new Entities in the Entities app

Scenario

Throughout production, quality and retain samples are collected at defined points in the process. In CAR T Processing, a quality sample is collected before cell washing, and a retain sample is collected post-wash.

In this exercise, you will be modeling the Entity Types collected at these points in the process.

Your Task

Part 1: As a Super User, you have been asked to create two (2) new Entity Types, Whole Blood Sample and Buffy Coat Sample. The Whole Blood Sample will be collected prior to cell washing for a cell count, while the Buffy Coat sample will be collected post-wash as a retain sample.

Entity Classes have already been configured, but you will need to decide which Class each Entity Type should belong to. You will also need to decide how to model the following fields:

Whole Blood Sample

  • Volume (mL)

    • Must be between 1 and 1.8 (no notification required)

    • Only display one (1) decimal place

Buffy Coat Sample

  • Component

    • Options include Platelets and White Blood Cells

  • Target Population (only displayed if White Blood Cells selected above)

    • B Cells

    • T Cells

    • NK Cells

Tip

To make a field conditionally visible, consider which L7|ESP Expression is used to reference an Entity value

  • Wash Method

    • Options include Lovo and Sepax

Part 2: Navigate to the the Entities app and create one (1) new Whole Blood Sample and one (1) new Buffy Coat Sample.

Does each Sample have the custom field(s) you created in Part 1?
