Two data types that are considered discrete units of work (code units) within a transaction in the debug logs are web service invocation and Apex class. A discrete unit of work (code unit) is a segment of executable code that runs as part of a transaction in Salesforce. A transaction is a sequence of operations that are treated as a single unit of work and are executed under certain isolation and consistency rules. A transaction can consist of one or more discrete units of work (code units) that are executed sequentially or concurrently depending on various factors such as triggers, asynchronous calls, or limits. A debug log is arecord of database operations, system processes, and errors that occur when executing a transaction or running unit tests in Salesforce. A debug log can capture information about each discrete unit of work (code unit) within a transaction, such as its start time, end time, duration, events, variables, and limits. A web service invocation is a type of discrete unit of work (code unit) that involves calling an external web service from Apex code using SOAP or REST protocols. A web service invocation can be synchronous or asynchronous depending on the method used to make the callout. A web service invocation can be captured in a debug log with its details and results. An Apex class is another type of discrete unit of work (code unit) that involves executing Apex code that defines a class with properties and methods. An Apex class can be invoked from various sources such as triggers, Visualforce pages, Lightning components, or API calls. An Apex class can be captured in a debug log with its details and results. A validation rule is not a type of discrete unit of work (code unit) within a transaction in the debug logs, as it is not a segment of executable code but rather a formula expression that defines a business rule for a field or object. A validation rule can be evaluated during a transaction and cause an error if the rule condition is not met, but it cannot be captured as a separate code unit in a debug log. A Lightning component load is not a type of discrete unit of work (code unit) within a transaction in the debug logs either, as it is not a segment of executable code but rather an event that occurs when a Lightning component is rendered on a web page or application. A Lightning component load can be measured by various performance tools such as Lightning Inspector or Lighthouse, but it cannot be captured as a separate code unit in a debug log.

To bring picklist values into a Lightning Web Component (LWC), a developer needs to import specific modules from thelwcandlightning/uiObjectInfoApinamespaces. ThegetPicklistValuesfunction from thelightning/uiObjectInfoApimodule is used to fetch the picklist values based on record type and field metadata. Additionally, importing{ LightningElement, wire }fromlwcis essential for defining the LWC class and using the@wiredecorator to wire thegetPicklistValuesto a property orfunction. Salesforce documentation on LWC and utilizing theuiObjectInfoApiprovides clear guidelines on how to implement this functionality.

The service method that should be overridden in order to allow “without sharing” queries is ccrz.ccService.initSVCDAO. This method is responsible for initializing the service data access object (SVCDAO) that is used by the service class to perform queries. By overriding this method, the user can specify the sharing mode of the SVCDAO, which will determine whether the queries respect or ignore the sharing rules of the current user. For example, ccrz.ccService.initSVCDAO(ccrz.ccAPI.SZ_WITHOUTSHARING) will initialize the SVCDAO with the without sharing mode.

The recommended method for increasing the number of required autocomplete characters that are typed before autocomplete works is to override the autoComplete.search_input.minLength value in the CCRZ.uiProperties file. This file contains various properties that control the behavior and appearance of the user interface components. The autoComplete.search_input.minLength property specifies the minimum number of characters that must be entered before the autocomplete feature is triggered. The default value is 3, but it can be changed to any desired value by overriding it in the CCRZ.uiProperties file. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, UI Properties

In a Lightning Web Component folder, the allowed file extensions include.js-meta.xmlfor the component's metadata,.htmlfor the component's markup, and.jsfor the component's JavaScript class. These files are essential for defining the structure, behavior, and metadata of a LWC. Salesforce LWC documentation provides detailed information on the structure of a LWC bundle and the purpose of each file type within it.

You should avoid using ccLog in two scenarios. First, you should avoid using ccLog with System.LoggingLevel.ERROR when passing in a method invocation as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.ERROR, ‘D:something’, myCallToGetMessage(pl) ). This is because if an exception occurs within the method invocation, it will not be caught by ccLog and will cause an unhandled exception on the page. Instead, you should use a try-catch block around the method invocation and log the exception separately. Second, you should avoid using ccLog with System.LoggingLevel.DEBUG when passing in a large collection or object as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.DEBUG, ‘D:myOrderList’, myOrderList), where myOrderList is a list of orders. This is because logging large objects can cause performance issues and consume a lot of heap space. Instead, you should use a loop to log only the relevant fields or properties of the object or collection. You can use ccLog with System.LoggingLevel.WARN when passing in a string as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.WARN, ‘D:something’, ‘Something unexpected occurred: The data we were expecting for pl was not there,’). This is a valid use case for logging a warning message. You can also use ccLog with System.LoggingLevel.DEBUG when passing in a small object as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.DEBUG, ‘D:myOrder’, myOrder), where myOrder is an order object. This is acceptable as long as the object is not too large or complex. Salesforce References: [B2B Commerce Developer Guide: Logging]

To implement a custom Terms and Conditions checkbox at checkout in the Aura Commerce template, a developer should add a Desired Delivery Date input field during the checkout flow. The Desired Delivery Date input field allows the customer to enter a date when they want their order to be delivered. The developer can use the @api decorator to expose this field as a public property of the Lightning web component and bind it to the ccCheckoutOrder object. The developer can also use the @wire decorator to get the current cart object and use its properties, such as shipping address and shipping method, to calculate and display an estimated delivery date based on the desired delivery date. The developer can also add validation logic to ensure that the desired delivery date is valid and acceptable. Adding the Expected Delivery Date field to the order confirmation email is not a good solution, as it does not allow the customer to choose or see their delivery date before placing their order. Displaying the Expected Delivery Date on the order page with a Lightning web component is not a good solution either, as it does not allow the customer to enter or change their delivery date after placing their order. Configuring an email alert to the customer when the Expected Delivery Date changes is not a good solution either, as it does not provide a consistent or reliable way of informing the customer about their delivery date.
