Question

在Microsoft Dynamics 365中，我想删除一个帐户记录，但是要删除处于活动状态的任何子联系人。处于非活动状态的联系人应正常删除。我该如何使用插件来实现这一目标？

Answer 1

不幸的是，Dynamics不允许我们更改“帐户到联系人1-N”关系中的级联删除，这意味着每次删除帐户时，与该帐户相关的所有联系人都会被删除。此关系也无法删除。

编辑：将下面的插件注册为 PreValidation 删除，它将生效（出于取消关联子记录的目的，请致谢@Sxntk）

public class AccountPreDeletePlugin : IPlugin
{
    public void Execute(IServiceProvider serviceProvider)
    {
        var tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
        var pluginExecutionContext = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
        var organizationServiceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
        var organizationService = organizationServiceFactory.CreateOrganizationService(pluginExecutionContext.UserId);

        if (pluginExecutionContext.InputParameters.Contains("Target") && pluginExecutionContext.InputParameters["Target"] is EntityReference entityReference)
        {
            var query = new QueryExpression("contact") { NoLock = true };
            query.Criteria.AddCondition("parentcustomerid", ConditionOperator.Equal, entityReference.Id);
            query.Criteria.AddCondition("statecode", ConditionOperator.Equal, 0);

            var entityCollection = organizationService.RetrieveMultiple(query);

            if (entityCollection?.Entities?.Count > 0)
            {
                foreach (var entity in entityCollection.Entities)
                {
                    entity["parentcustomerid"] = null;
                    organizationService.Update(entity);
                }
            }
        }
    }
}
