What Do You Understand By Workflow In Salesforce

  • Workflow in Salesforce allows you to automate standard internal procedures and processes for saving time across your organization. It helps to evaluate records as they are created or updated and determines if an automated action needs to occur.
  • Automation functions in Salesforce include the functions such as sending follow-up emails, tracking the customer map journey, performing other marketing activities to boost the sales of the company, etc.
  • A workflow rule is a major container for a set of workflow instructions. These instructions are usually summed up in an if/then statement. Workflow rules are divided into two main components. They are:
  • Criteria: The if part of the if/then statement i.e., what must be true of the record for the workflow rule to execute the related actions.
  • Actions: The then part of the if/then statement i.e., what to do when the record meets the criteria.
  • Consider an example for a workflow, if it is raining, then bring an umbrella. In this example, the criteria are it is raining and the action is bring an umbrella. If the criteria arent met, then the action isnt executed. The workflow rules actions are executed only when a record meets all the criteria of a workflow rule.

    In the process, the custom object has to be defined first, and then the following steps need to be followed:

    • Join records with the custom object
    • Custom object data is displayed in custom lists
    • Create a custom tab for the custom object
    • Build page layouts
    • Create a dashboard and a report for analyzing the custom object

    Moreover, the custom tab, app, and object can be shared

    Describe The Different Ways To Make A Field Required In Salesforce

    Making fields required in Salesforce is a great way to ensure that correct information is being captured and at the right point in the process. Over time, this massively improves data quality. Here are a few ways you can make fields required

    • Custom Field Settings Whenever you create a new custom field, you have the option to make this required. This is a hard limit and will be required whenever you are creating a new record inside of Salesforce or uploading via a data loader.
    • Page Layout On a Salesforce Page Layout, you also have the option to make fields read-only, or required. This is considered a soft limit, as it will only apply if you are creating a new record via the Salesforce interface, not when uploading via a data loader.
    • Validation Rules Finally, we have validation rules. These have much more advanced logic and can be built to only make a field required, under a certain condition, e.g. If Opportunity Stage = Closed Won, make X field required. Validation rules have a hard limit.

    What Is Reallifetestingtm

    Salesforce Interview Questions And Answers | Salesforce Tutorial | Salesforce Training | Edureka

    The driving force behind all DevSkiller Salesforce developer interview questions is the RealLifeTestingTM methodology. This is an advanced testing system that goes beyond traditional coding tests and algorithm puzzles, to provide recruiters with a holistic view of a developers skills. It should go without saying that the best way to evaluate a developers skills is by presenting them with challenges similar to the work which they will be required to do, but up until now, this is not how developer testing was carried out.

    RealLifeTestingTM creates a simulated reality for the candidate and challenges them with tasks similar to those they encounter every day. The developers who are great in their everyday work will have no problem progressing through the challenges.

    During testing, candidates can build full project apps or add features to existing apps, just like they would once hire. They can demonstrate their knowledge of coding, use resources like Stack Overflow to find solutions, and use their problem-solving skills to progress through to the next stage of recruitment.

    What Is A Queue

    Queues are similar to Public Groups in that they are bespoke groupings of users , but they are used Queues are similar to public groups in that they are bespoke groupings of users , but they are used for record ownership rather than sharing rules. The classic use is for Cases where youd want to assign an open one to a team of people so that whoever is available first handles it. Queues are available on all custom objects and many standard objects.

    How Can We Respond To User Interactions

    Regardless of the framework used the answer remains the same, events. However, how we define how to handle these events differs slightly by framework, but both are required to define event handlers.

    In Aura, we define handler code within our components controller. We can then tell our component to listen to and then run our code when the events are fired in several different ways. The simplest is to add an inline event handler on to the component that fires it. The second way is to add an aura:handler tag. Both expect to be pointed towards an action in the controller which handles the event.

    Handling events in LWC is a much simpler affair than within Aura components since the events are standard JavaScript events. We can either use inline event handlers on the elements which fire it or add event handlers to our component dynamically through JavaScript.
