Salesforce for Facebook and Twitter installation error

Knowledge Article Number 000175597
Description When we try Salesforce for Facebook and Twitter installation we receive an error:

Problem:

1. (ObjectX.Twitter_User_Id__c) reached maximum number of external ids and unique fields

ObjectX.Twitter_User_Id__c: reached maximum number of external ids and unique fields

 

Validation Errors While Saving Record(s)

 

There were custom validation error(s) encountered while saving the affected record(s). The first validation error encountered was "00XX0000000XxXx: VALIDATION_FAILED [Contact.Twitter_User_Id__c: reached maximum number of external ids and unique fields: ObjectX.Twitter_User_Id__c: reached maximum number of external ids and unique fields]".
Resolution If we receive the above error then we have reached our Salesforce.com Orgs limit on the number of fields or the number of fields with external id's on the related ObjectX.

To resolve this issue,we should check for that ObjectX  related number of fields with external or unique id's.If there are any fields which are no longer used & assigned these external or unique id's.

We should make sure that we delete those fields or remove the external or unique id's feature for those fields,then the installation would be successful.

And if the fields are important & there are no fields to be deleted,then the user has to request to increase the number of external ids and unique fields from salesforce.com apparently as there is a limited on number external & unique id fields in their system the installation should be successful once the above limit is increased set as per requirement
