Subline Change Line Subline Updater Class

After a user updates a field on a parameter subline, this Apex hook can update fields on the parent line fields, and one or more fields on one or more sublines of that parent line.

Apex hook class

• It must implement the SublineChangeLineSublineUpdater interface.
• It must have a global access modifier.
• You must specify the Apex hook class name in the Subline Change Updater Class Name field of the Product Selector Configuration.

Interface definition

global interface SublineChangeLineSublineUpdater
{
    LinesAndSublinesResponse updateLineSublinesOnSublineChange(LinesAndSublinesInputData data);
}

global class LinesAndSublinesInputData {
    @AuraEnabled global SObject changedSObject { get; private set; }
    @AuraEnabled global SObject line { get; private set; }
    @AuraEnabled global String changedFieldName { get; private set; }
    @AuraEnabled global List<SObject> parameterSublines { get; private set; }
    @AuraEnabled global List<SObject> tieredSublines { get; private set; }
 
    global LinesAndSublinesInputData(SObject changedSObject, String changedFieldName, SObject line, List<SObject> parameterSublines, List<SObject> tieredSublines) {
        this.changedSObject = changedSObject;
        this.line = line;
        this.changedFieldName = changedFieldName;
        this.parameterSublines = parameterSublines;
        this.tieredSublines = tieredSublines;
    }
}

As an input parameter, this method has LinesAndSublinesInputData which contains changedSObject (the object that was updated by user), a line, a changedFieldName (the field that was changed by the user on changedSObject), parameterSublines and tieredSublines.

As a return value, the method has LinesAndSublinesResponse which contains an updated line, parameterSublines and tieredSublines.

Example of the LinesAndSublinesResponse

global class LinesAndSublinesResponse {
    @AuraEnabled global SObject line;
    @AuraEnabled global List<SObject> parameterSublines;
    @AuraEnabled global List<SObject> tieredSublines;
 
    global LinesAndSublinesResponse(SObject line, List<SObject> parameterSublines, List<SObject> tieredSublines)
    {
        this.line = line;
        this.parameterSublines = parameterSublines;
        this.tieredSublines = tieredSublines;
    }
}

Example of the class implementation

public with sharing class TestLineSublinesUpdaterOnSublineChange implements SublineChangeLineSublineUpdater{
    public LinesAndSublinesResponse updateLineSublinesOnSublineChange(LinesAndSublinesInputData data) {
        if ((String) data.changedSObject.get('zpl__ups_UOM__c') == 'test' && data.changedFieldName == 'zpl__ups_UOM__c') {
            data.line.put('zpl__ContractPrice__c', 100);
 
            for (SObject tieredSublines : data.tieredSublines) {
                tieredSublines.put('zpl__ups_UOM__c', 'update');
                tieredSublines.put('zpl__ups_Offer__c', 123);
                tieredSublines.put('zpl__ups_Guidance__c', 1111);
                tieredSublines.put('tbesh__Currency__c', 100);
            }
 
            for (SObject parameterSubline : data.parameterSublines) {
                parameterSubline.put('zpl__ups_Guidance__c', 1111);
            }
        }
 
        return new LinesAndSublinesResponse(data.line, data.parameterSublines, data.tieredSublines);
    }
}
