updating state and attribute values using plugin - crm

Question

I am trying to update both the state and value of an attribute for an entity by writing plugin for CRM 2013. I did try to set the state of an activity using setStateRequest but I am not sure if we can update attribute value as well. I've registered the plugin on Merge message to change the state of an activity. How can I update an attribute value along with state change? Here is my code so far for state ch
protected void ExecutePreCaseMerge(LocalPluginContext localContext)
{
if (localContext == null)
{
throw new ArgumentNullException("localContext");
}
// TODO: Implement your custom Plug-in business logic.
IPluginExecutionContext context = localContext.PluginExecutionContext;
IOrganizationService service = localContext.OrganizationService;
//The InputParameters collection contains all the data passed in the message request.
if (context.InputParameters.Contains("SubordinateId") &&
context.InputParameters["SubordinateId"] is Guid)
{
try
{
Guid subordinateId = (Guid)context.InputParameters["SubordinateId"];
var fetch = #"<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>
<entity name='task'>
<attribute name='new_issuephase' />
<filter type='and'>
<filter type='and'>
<condition attribute='regardingobjectid' operator='eq' uitype='incident' value='" + subordinateId + #"' />
<condition attribute='statecode' operator='eq' value='0' />
</filter>
</filter>
</entity>
</fetch>";
EntityCollection ec = service.RetrieveMultiple(new FetchExpression(fetch));
if (ec.Entities.Count > 0)
{
// Create an ExecuteMultipleRequest object.
ExecuteMultipleRequest requestWithResults = new ExecuteMultipleRequest()
{
// Assign settings that define execution behavior: continue on error, return responses.
Settings = new ExecuteMultipleSettings()
{
ContinueOnError = false,
ReturnResponses = true
},
// Create an empty organization request collection.
Requests = new OrganizationRequestCollection()
};
foreach (var item in ec.Entities)
{
SetStateRequest setStateRequest = new SetStateRequest();
setStateRequest.EntityMoniker = new EntityReference("task", item.Id);
setStateRequest.State = new OptionSetValue(2);
setStateRequest.Status = new OptionSetValue(6);
requestWithResults.Requests.Add(setStateRequest);
}
ExecuteMultipleResponse responseWithResults =
(ExecuteMultipleResponse)service.Execute(requestWithResults);
}
}
ange.
Thanks for any help!

You must do the update as a separate request but you can execute it together with the SetStateRequests inside the same ExecuteMultipleRequest:
foreach (var item in ec.Entities)
{
SetStateRequest setStateRequest = new SetStateRequest();
setStateRequest.EntityMoniker = new EntityReference("task", item.Id);
setStateRequest.State = new OptionSetValue(2);
setStateRequest.Status = new OptionSetValue(6);
requestWithResults.Requests.Add(setStateRequest);
//New Code
item.Attributes["attributetobeupdated"] = "Updated Value";
UpdateRequest request = new UpdateRequest() { Target = item };
requestWithResults.Requests.Add(request);
}
ExecuteMultipleResponse responseWithResults =
(ExecuteMultipleResponse)service.Execute(requestWithResults);
Note that if any of the requests fail the ExecuteMultipleRequest will not throw an error but will return the details of the individual failures within the ExecuteMultipleResponse. It seems that a common reason for this operation failing is that by default SQL server queries are configured to time out after 30 seconds. More info here:
