if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
{
Entity acc_entity = (Entity)context.InputParameters["Target"];

var query = new QueryExpression("contact")
{
ColumnSet = new ColumnSet("contactid"),

};
query.Criteria.AddCondition("parentcustomerid", ConditionOperator.Equal, acc_entity.Id);

EntityCollection results = service.RetrieveMultiple(query);

results.Entities.ToList().ForEach(x =>
{
// Console.WriteLine(x.Attributes["contactid"]);

EntityReference contact_ref = x.GetAttributeValue<EntityReference>("contactid");
Entity contact = service.Retrieve("contact", contact_ref.Id, new ColumnSet(new string[] { "fax" }));
contact["fax"] = "789456";
service.Update(contact);
});

Hi,

var query = new QueryExpression("contact") { ColumnSet = new ColumnSet(false), }; query.Criteria.AddCondition("parentcustomerid", ConditionOperator.Equal, acc_entity.Id); EntityCollection results = crmSvc.RetrieveMultiple(query); results.Entities.ToList().ForEach(x => { Entity contactToUpdate = new Entity(x.LogicalName, x.Id); contactToUpdate["fax"] = "789456"; service.Update(contactToUpdate); });
