Validating Opportunity Conditions in Salesforce Using Apex


public class OpportunityValidation {
    public static Boolean isValidUser(Opportunity opp) {
        // Check if Stage is 'Closed' or 'Review'
        Boolean isStageValid = (opp.StageName == 'Closed' || opp.StageName == 'Review');
       
        // Check if Status is 'Pending - BSC Meeting'
        Boolean isStatusValid = (opp.Status__c == 'Pending - BSC Meeting');
       
        // Check if the current user is part of the public group 'GROUPB'
        Boolean isInGroupB = [SELECT Count()
                              FROM GroupMember
                              WHERE Group.DeveloperName = 'GROUPB'
                              AND UserOrGroupId = :UserInfo.getUserId()] > 0;
       
        // Check if the current user's profile is 'RISK'
        Boolean isRiskProfile = [SELECT Profile.Name
                                 FROM User
                                 WHERE Id = :UserInfo.getUserId()].Profile.Name == 'RISK';

        // Return true if all conditions are met, otherwise false
        return isStageValid && isStatusValid && !isInGroupB && !isRiskProfile;
    }
}

Explanation:

Stage and Status Check:

isStageValid checks if the StageName field on the Opportunity record is 'Closed' or 'Review'.
isStatusValid checks if the custom Status__c field on the Opportunity record is 'Pending - BSC Meeting'.

Group Membership Check:

The isInGroupB query checks if the current user is a member of the public group with the developer name 'GROUPB'. It uses GroupMember to verify if the current user's ID is associated with that group.

Profile Check:

The isRiskProfile query checks if the current user's profile name is 'RISK'.

Return Statement:

The method returns true only if all the conditions are satisfied: the stage and status match the criteria, the user is not part of 'GROUPB', and the user does not have the 'RISK' profile.
