Limitations in Similar Opportunities in Salesforce

1. Use the Similar Opportunities related list on the opportunity’s detail page to find Closed/Won opportunities with common information.

2. The criteria used to find similar opportunities is determined by your administrator. The search finds a maximum of 10,000 opportunities with close dates in a three-month period and displays up to 300 of the records that best match the search criteria. The results are ranked by the number of matching fields.

3. Results can be filtered by Close date or by matching fields.

4. To see how a record in the search results is similar to your current deal, hover over the opportunity name. The matching fields are highlighted in the Match Criteria sidebar.

Einstein Builder:

What happens if 24 hour Platform Event limit is hit?

Platform event limits apply to a 24-hour cycle. Before delivering new events, such as a change in order status, to subscribed clients, Salesforce checks your allocation and how many events have been used in your Salesforce org in the last 24 hours. If the number of events used is lower than the 24-hour allocation, Salesforce delivers events to subscribers. If you did hit your allocation for events in the previous 24 hours, Salesforce doesn’t deliver new events. But, they’re queued within a brief time window until event allocation is available.

For other limitations in Platform Event - https://developer.salesforce.com/docs/atlas.en-us.212.0.platform_events.meta/platform_events/platform_event_limits.htm

Calling Apex method from another Apex method callback in Salesforce Lightning

Sample Code:

Lightning Component:

<aura:component implements="force:appHostable"
                controller="Sample">

    <div class="slds-box slds-theme_default">
<lightning:button variant="brand" label="Click" onclick="{!c.call1}"/>        
    </div>
    

</aura:component>

Lightning Component Controller:

({
call1 : function(component, event, helper) {
var action = component.get("c.firstMethod");
        action.setParams({
        });
        action.setCallback(this, function(response){
            var state = response.getState();
            if (state === "SUCCESS") {
                if ( response.getReturnValue() === 'error' ) {
                    $A.enqueueAction(component.get('c.call2'));
                }
            }
        });
        $A.enqueueAction(action);
},
    call2 : function(component, event, helper) {
        var action = component.get("c.secondMethod");
        action.setParams({
        });
        action.setCallback(this, function(response){
            var state = response.getState();
            if (state === "SUCCESS") {
                alert(response.getReturnValue());
            }
        });
        $A.enqueueAction(action);
    }

})

Apex Class:

public class Sample {

    @AuraEnabled
    public static String firstMethod() {
        return 'error';
    }
    
    @AuraEnabled
    public static String secondMethod() {
        return 'Success';
    }
    

}

Output:

What is the difference between @RestResource and @InvocableMethod?

RestResource Annotation 
The @RestResource annotation is used at the class level and enables you to expose an Apex class as a REST resource. @RestResource is at the class level. It is used to expose a class as rest source.

Example - http://www.infallibletechie.com/2017/08/simple-inbound-rest-api-using-apex-in.html

InvocableMethod Annotation 
Use the InvocableMethod annotation to identify methods that can be run as invocable actions. Invocable methods are called with the REST API and used to invoke a single Apex method. Invocable methods have dynamic input and output values and support describe calls. @Invocable Method is used at the method level. these are called with REST API and it is used to invoke a single method.

What happens if time-dependent actions sets the trigger date to past date in Salesforce?

If Salesforce recalculates the time triggers to a date in the past, Salesforce triggers the associated actions shortly after you save the record.

If a workflow rule has a time trigger set for a time in the past, Salesforce queues the associated time-dependent actions to start executing within one hour. For example, if a workflow rule on opportunities is configured to update a field 7 days before the close date, and you create an opportunity record with the close date set to today, Salesforce starts to process the field update within an hour after you create the opportunity.

Sample Scenario to set Past Time:

How to restrict users login access based on country in Salesforce?

Transaction Security feature can be used to restrict users login access based on country in Salesforce.

To know about Transaction Security and setting up use the below link

http://www.infallibletechie.com/2016/11/transaction-security-in-salesforce.html

Sample Apex Code:

global class IndiaOnlySecurityPolicyCondition implements TxnSecurity.PolicyCondition {

    public boolean evaluate(TxnSecurity.Event e) {
        LoginHistory eObj = [SELECT CountryISO FROM LoginHistory WHERE Id = :e.data.get('LoginHistoryId')];
        if ( eObj.CountryISO == 'IN' ) {
            return false;
        }        
        return true; 
    }

}

The above code will allow only users to log in from Country India.

Note:
Please do not do this in Production. It may not allow you to log in if set incorrectly. Try to bypass system administrator profile to avoid issues.
