Swagat.Tushar Update picklist values and their dependencies using Metadata API
Hi All,
Requirement: To update four picklist field values with dependencies on any object. As the numbers of picklist values are high it’s difficult to manage the Field Dependencies manually.
Product Family
Product Line
Product Module
Product Version
Design Approach: So we planned to go for customization. We used four custom settings to store the picklist values. Then update the picklist fields values using Metadata API.
Below are the design of four custom settings.
Product Family
Family1
Family2
Family3
Product Line
Family1 - Line1
Family2 - Line2
Family3 - Line3
Product Module
Line1 - Module1
Line1 - Module2
Line2 - Module2
Product Version
Line1 - Version1
Line1 - Version1
Line2 - Version2
Problem: Though the above design works for less volume of data, when i am trying to update 1000 picklist values the system is not updating the values. I tried to debug my code but there is also an i

Any words of advice or any other approach/solution?

The controlling field values provided are not actually present in the controlling field.
So the async call was not succeeding and the result was “Error” with the message “FIELD_INTEGRITY_EXCEPTION”.

Hi swagat i think your post can help me. My post is this
http://boards.developerforce.com/t5/Apex-Code-Development/Add-delete-values-in-pick-list-through-apex-and-visualforce/td-p/707015
you are using depandencies but i have only one picklist and need to retrieve and add/delete values inside picklist through visualforce and apex. can you help me ?
public PageReference AddPicklistValue() { //Get the picklist values. I am getting here from a custom setting //Name of custom setting - "PicklistValues__c" //One field in custom setting with name "Services__c" List<PicklistValues__c> lstPicklistValues = Product_Family__c.getall().values(); MetadataClass.MetadataPort objMetadataClass = new MetadataClass.MetadataPort(); objMetadataClass.SessionHeader = new MetadataClass.SessionHeader_element(); objMetadataClass.SessionHeader.sessionId = UserInfo.getSessionId(); MetadataClass.CustomField customField = new MetadataClass.CustomField(); customField.fullName = 'Client__c.Services__c'; customField.label = 'Services'; customField.type_x = 'Picklist'; MetadataClass.Picklist pt = new MetadataClass.Picklist(); pt.sorted= true; pt.picklistValues = new list<MetadataClass.PicklistValue>(); for(PicklistValues__c objPicklistValues : lstPicklistValues){ MetadataClass.PicklistValue plValue = new MetadataClass.PicklistValue(); plValue.fullName=objPicklistValues.Services__c; plValue.default_x=false ; pt.picklistValues.add(plValue); } customField.picklist = pt ; MetadataClass.UpdateMetadata ut = new MetadataClass.UpdateMetadata(); ut.currentName='Client__c.Services__c'; ut.metadata= customField; MetadataClass.AsyncResult[] results = objMetadataClass.updateMetadata(new List<MetadataClass.updateMetadata> {ut}); return null; }Please check the above code. This might work. I am getting the values from a custom setting. You can get the values from VF input.
Please download the Metadata API and generate an apex class with name "MetadataClass" and use the same.
