Apex Classes for Document Generation Process Cleaner Utility

Create the following class in your org, and modify it as needed.

public class DocumentGenerationProcessCleanerUtility {

    List<String> statusList = new List<String>{'Success', 'Failure'};               // list of statuses considered for deletion
    Integer batchSize = 2000;                                                       // batch size for deletion used in BatchDeleteHelper, 2000 is max batch size possible

    String query = 'select Id, TokenDataContentDocumentId from DocumentGenerationProcess  WHERE LastModifiedDate >= :dstart and LastModifiedDate <= :dend and  TokenDataContentDocumentId != NULL and status IN :statusList';

    // Given 'dstart','dend' datetime, delete all documentGenerationProcess records that use TokenDataContentDocument field and have LastModifiedDate = ['dstart','dend'], also delete associated contentDocuments
    public  void cleanDocumentGenerationProcessAndContentDocument(Datetime dstart,Datetime dend) {
      System.Debug('Deleting DocumentGenerationProcess records along with used contentDocuments ...');
      ID batchjobid = Database.executeBatch(new BatchDeleteHelper(false,query,dstart,dend, statusList), batchSize);
      System.debug('Started batch job with ID: ' + batchjobid);
    }

    // Given 'dstart','dend' datetime, for all documentGenerationProcess records that use TokenDataContentDocument field and have LastModifiedDate = ['dstart','dend'] delete associated contentDocuments only
    public  void cleanContentDocument(Datetime dstart,Datetime dend) {
       System.Debug('Deleting only contentDocuments associated with DocumentGenerationProcess records ...');
      ID batchjobid = Database.executeBatch(new BatchDeleteHelper(true,query,dstart,dend,statusList), batchSize);
      System.debug('Started batch job with ID: ' + batchjobid);
    }
}
