To allow three physicians to review the orders in parallel, you need to use the "Split For Each" shape. This shape enables parallel processing for each item in a list, such as the list of physicians.

Understanding Split For Each Shape in Pega:The "Split For Each" shape allows you to create instances of a subprocess for each item in a specified list. This means each physician can independently review and evaluate the surgical procedure requests simultaneously.

Configuration Steps:

Step 1: Create a list of physicians who will be performing the evaluations.

Step 2: Add a "Split For Each" shape to the process flow.

Step 3: Configure the "Split For Each" shape to iterate over the list of physicians.

Step 4: Define the evaluation subprocess to be called for each physician.

Step 5: Ensure that each physician's evaluation subprocess is independent of the others.

Advantages of Using Split For Each:This approach allows all three physicians to perform their evaluations simultaneously, reducing the overall processing time and ensuring that the process can advance as soon as two out of three evaluations are completed.

References:Pega Documentation on Split For Each shape provides detailed steps on how to configure and use this shape in your process flows.

 In a decision strategy, to use a customer property in an expression, you need to prefix the property with the keyword Customer.

 This ensures that the property is correctly identified and retrieved from the customer data page.

In attribute-based access control (ABAC) configuration, if you need to evaluate attributes from a data page, you should use the data page as the policy condition value in the access control policy condition. This allows the system to evaluate the current value from the data page when enforcing access control rules.

To configure a data page that accepts either a postal code or a city name as a parameter and calls the appropriate REST connector:

Use separate REST connectors for each parameter type and a when rule to determine which connector to use based on the input parameter.

Alternatively, use an activity to evaluate the parameter and dynamically select the appropriate REST connector at runtime.

To configure a process where three physicians can independently perform evaluations and ensure that only two evaluations are necessary to advance the case to the medical director, you should use the "Some" join condition in Pega.

Understanding Join Conditions in Pega:Pega provides various join conditions to handle subprocesses. The join conditions include "Any," "Some," and "All." These conditions dictate how and when the main process can proceed based on the completion of subprocesses.

Some Join Condition:The "Some" join condition allows the main process to advance once a specified number of subprocesses have been completed successfully. In this scenario, since only two out of the three physicians need to complete their evaluations for the case to move forward, the "Some" join condition is appropriate.

Configuration Steps:

Step 1: Define the subprocesses for the physicians' evaluations.

Step 2: Use the "Split For Each" shape to create multiple subprocesses.

Step 3: Configure the "Some" join condition and set the number of required completions to 2.

Step 4: Ensure that the main process waits for two evaluations before moving to the medical director review.

References:Pega Documentation on Join Conditions provides detailed steps and examples for configuring different join conditions, including the "Some" join condition.
