Data driven subscription query returns no data
We have a data driven subscription on SSRS 2008 R2. The columns in the query are tied to one or more parameters of the report. When we run the subscription and if the query does not return any rows, I was hoping that the subscription will not start; however,
instead, to my surprise, I got error stating..."Parameter XYZ value can't be null". How to avoid this error and keep subscription from running in this situation?
Example: I have a report that required employeeID as a parameter. I have a query (step 3: data driven subscription) that fetches employee ID based on some criteria. If there is no row returned by the query; It throws error on report stating "Parameter
EmployeeID can't be null."

Hello Nehal -
Try adding a UNION ALL to your parameter dataset query like
UNION ALL SELECT NULL AS EmployeeID , ..
Just check accordingly. I ll revert again based on this , got a priority now.
Happy to help! Thanks. Regards and good Wishes, Deepak. http://deepaksqlmsbusinessintelligence.blogspot.com/

Creating Data Driven Subscription does not allow me to get Auto copy from Query.
I am trying to create a data driven Subscription for sharepoint document Library. I have a table I populate with values. Then a stored procedure that exec and returns the values. I use this in my data driven subscription.
Here is what my table looks like
intSubscriptionID strSubscriptionName strFileName strPath strRenderFormat strWriteMode strFileExt strTitle strAutoCopy strUserName strPassword strVar1 strVar2 strVar3 strVar4 strVar5 strVar6 strVar7 strVar8 strVar9 strVar10 bitEnabled
400 Billing - Invoice_ParentChildRollup 19_Jan2015 http://eagleviewportal/BusinessIntelligenceCenter/AccountingBI/Reports/New Excel Overwrite True Invoice_ParentChildRollup False NULL NULL 0000019 NULL NULL NULL NULL NULL NULL NULL NULL NULL 1
401 Test Daily Order and Pending Status by SubAccount Test Daily Order and Pending Status by SubAccount http://eagleviewportal/BusinessIntelligenceCenter/ClientRelationsBI/Reports/New Excel Overwrite True Test
Daily Order and Pending Status by SubAccount True NULL NULL 152884 NULL NULL NULL NULL NULL NULL NULL NULL NULL 1
I can use all the values and it creates my subscription no problem as long as I do not try to use the autocopy.
If I select Use no Value all works great.
If I select Specify a static Value and then choose True it gives me an error The AutoCopy Delivery setting cannot be set to True if the WriteMode Delivery setting is not set to Overwrite. as you can see that value is set to overwrite. If I use
hard coded word OverWrite instead of getting it from query it works.
If I do the same step above but select False it seems to work as well.
If I try to choose the value from the query then it errors with the generic Sorry Something went wrong. I cannot find any value in url logs.
Ken CraigHi Ken,
I have reproduced the same issue as you encountered. If you choose both value for the fields(WriteMode and AutoCopy) from query, SharePoint will result in an error page. I finally fixed the issue by manually updating the table
dbo.Subscriptions from the reporting service database. To make this, please first copy the value of field
ExtensionSettings from the subscription table.
Change the WRITEMODE and AUTOCOPY from "<ParameterValue><Name>WRITEMODE</Name><Value>Overwrite</Value></ParameterValue> <ParameterValue><Name>AUTOCOPY</Name><Value>AutoCopy</Value></ParameterValue>"
to "<ParameterValue><Name>WRITEMODE</Name><Field>strWriteMode</Field></ParameterValue> <ParameterValue><Name>AUTOCOPY</Name><Field>strAutoCopy</Field></ParameterValue>".
Here Value means the static value, and field means the name of the query field. After you modify it, copy the settings back to field
ExtensionSettings or use update SQL to update it.
At last, your data driven subscription should be like this:

Hi,
We are getting the following error when certain data driven subscriptions are fired off: "the query processor could not start the necessary thread resources for parallel query execution". I've read other posts that have the same error, and
the solution usually involves adjusting MaxDOP to limit the number of queries that are fired off in parallel.
Unfortunately, we cannot change this setting on our server for performance reasons (outside of data driven subscriptions, it negatively impacts our ETL processing times). We tried putting query hints like "OPTION (MAXDOP 2);" in the reports
that are causing the error, but it did not resolve the problem.
Are there any settings within Reporting Services that can be adjusted to limit the number of subscriptions that get fired off in parallel?
Any help is appreciated - thanks!Yes, that is correct. It's a painful problem, because you don't know which specific subscription failed. For example, we have a data driven subscription that sends out about 800 emails. Lately, we've been having a handful of them fail. You don't know
which ones out of the 800 failed though, even from the RS log files - all it tells you is that "the
query processor could not start the necessary thread resources for parallel query execution".
Thanks, I'll try changing <MaxQueueThreads> and will let you know if it works.
On a side note: I've noticed that it is only reports with cascading parameters (ex. where parameter 2 is dependent on the selection from parameter 1) that get this error message... -
Introduction
In SQL Server Reporting Services, we can define a mapping between the fields that are returned in the query to specific delivery options and to report parameters in a data-driven subscription.
For a report with a parameter (such as YEAR) that allow multiple values, when creating a data-driven subscription, how can we pass a record like below to show correct data (data for year 2012, 2013 and 2014).
EmailAddress Parameter
Comment
[email protected] 2012,2013,2014 NULL
In this article, I will demonstrate how to configure a Data Driven Subscription which get multi-value parameters from one column of a database table
Workaround
Generally, if we pass the “Parameter” column to report directly in the step 5 when creating data-driven subscription.
The value “2012,2013,2014” will be regarded as a single value, Reporting Services will use “2012,2013,2014” to filter data. However, there are no any records that YEAR filed equal to “2012,2013,2014”, and we will get an error when the subscription executed
on the log. (C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\LogFiles)
Microsoft.ReportingServices.Diagnostics.Utilities.InvalidReportParameterException: Default value or value provided for the report parameter 'Name' is not a valid value.
This means that there is no such a value on parameter’s available value list, this is an invalid parameter value. If we change the parameter records like below.
EmailAddress Parameter Comment
[email protected] 2012 NULL
[email protected] 2013 NULL
[email protected] 2014 NULL
In this case, Reporting Services will generate 3 reports for one data-driven subscription. Each report for only one year which cannot fit the requirement obviously.
Currently, there is no a solution to solve this issue. The workaround for it is that create two report, one is used for view report for end users, another one is used for create data-driven subscription.
On the report that used create data-driven subscription, uncheck “Allow multiple values” option for the parameter, do not specify and available values and default values for this parameter. Then change the Filter
From
Expression:[ParameterName]
Operator :In
Value :[@ParameterName]
To
Expression:[ParameterName]
Operator :In
Value :Split(Parameters!ParameterName.Value,",")
In this case, we can specify a value like "2012,2013,2014" from database to the data-driven subscription.

How to pass multi-value parameters to DDS (data driven subscription)?
Using RS2005, how should multivalue parameters be stored in a database field so that a data driven subscription can properly read and use them? I have so far had no luck using syntax of:
1) parm1, parm2
2) parm1,parm2
Do single qutoes need to explicitly wrap the values? Can you please provide an example and a SQL INSERT statement using parm1 and parm2 to demonstrate what to store in the database field?
Thanks!!I have skimmed through this an have ran into this problem before but not with RS specifically, but with other ASP.NET apps I have built. Maybe this work around will help.
In my database I created a table function I call udf_Split List. It looks like this: (Can't remember where I got this from, but it's not my own.)
CREATE
FUNCTION [dbo].[udf_SplitList]
@List
varchar(max),
@SplitOn
nvarchar(5)
RETURNS
@RtnValue table
Id
int
identity(1,1),
Value
nvarchar(100)
AS
BEGIN
While
(Charindex(@SplitOn,
@List)
> 0)
Begin
Insert
Into @RtnValue
(value)
Select Value
=
ltrim(rtrim(Substring(@List,
1,
Charindex(@SplitOn,
@List)
- 1)))
Set @List
=
Substring(@List,Charindex(@SplitOn,
@List)
+
len(@SplitOn),
len(@List))
End
Insert
Into @RtnValue
(Value)
Select Value
=
ltrim(rtrim(@List))
Return
END
Then, in my query I used the following parameter: QueriedField IN(select value from dbo.udf_SplitList(@Parameter,',') (I used commas to separate the list, but you can use whatever you like (;,|,*, etc.)
For you @Parameter would be your DDS list parameter. Hope this helps. You can enter your list like Item1,Item2,Item3 etc. -
Special Characters in the file name in Data Driven Subscription via File Share
Hi,
I am trying to create a Data Driven Subscription with option to delivery as windows file share in SQL server 2005. I need to save the report as a pdf with the following file name '[City] City_Name', but it errors out and it is because of the
Square Brackets. Is there any way i can save the file using the Square brackets as i mentioned above.
I am using a query to get the filename and filepath. It works fine as long as i do not have [], but i need to save the file as i mentioned along with the Square Brackets.
Please help.Hello,
I can reproduce the issue on my test environment: When I create a Data Driven Subscription and specify the report name by get from a subscription delivery table, and the value of the "report name" column contains square brackets. The subscription failed
with following error in the error log:
ERROR: Error occurred processing subscription ab9523a6-0256-4607-b818-a7666204d018:
The file name is not valid. Avoid using special characters such as /\?*:<>|+,[]"& in the file name.

It seems that the behavior is by design. please avoid using square brackets as file name. Maybe you can try to use parentheses () instead.

According to your code, you are trying to create a data driven subscription with the code. As per my understanding, the issue can be caused by the FieldAlias does not exactly match a field in the dataset that is a part of the data retrieval plan, then the
error is thrown. Note that exactly match includes case and leading/trailing whitespace.
So please make sure the fields name are exactly matched in the code. The following blog posted by Gouri Sohoni is for your reference:

Hope this helps.

santoshHi Santosh,
Based on your error message, it's has issue in the parameters arguments when you call the createDataDrivenSubscription() function. we suggest you to check your parameters argument to createDataDrivenSubscriptio() function. Mostly it's the issue of the
Parameters. You are passing a ParameterFieldReference array object called parameters. The web service is very strict with the FieldAlias property. It need the fieldAlias have to EXACTLY MATCH a field in the data set that
is part of the data retrieval plan, otherwise it will throw the exception above. So please pay attention to the white space or lower/higher cap issue. Also we suggest you use functions like Trim() to make fieldAlias fit the field in dataset.
Reference:
The required field Field is
missing from the input structure.

SSRS Data Driven Subscription Done: 9 processed of 9 total; 9 errors.
Getting this error when running a data driven subscription on SQL Server 2008R2, Server is Windows Server 2008R2. Looked at the following.
Report takes no parameters and I can view it/export it just fine from the report server website.
I can run the query used in the data driven query to list emails/etc.
I verified no errors in the SSRS Execution Log Table (all rsSuccess)
Log File from SSRS shows what looks to be proper execution
From the SSRS box I can telnet port 25 to the smtp mail server we are using for sending emails. (below)
Report has been running daily for ~3 monthes.
Nothing obvious in the Event Log.
Anyone have any other thoughts on a place to check?

You can check the below blogs for troubleshooting subscriptions. Find the Schedule ID of the most recent subscription by querying the ReportServer database and search for the Schedule ID in your Trace Log to find the relative error message.

SSRS Data Driven Subscription - Analysis Services OLE DB Provider Not Recent Enough
We are creating new SSRS Data Driven Subscription. After entering the command query (which has been tested and is valid) we are getting the following error when the wizard validates the query in step 3:
The dataset cannot be generated. An error occurred while connecting to a data source, or the query is not valid for the data source. (rsCannotPrepareQuery). The current version of Analysis Services OLE DB Provider is not recent enough to perform
this check.
The data source involved and the query are all working as we have reports running on this server that use this data source. We've looked into the OLE DB Provider and both the SSAS server and the SSRS server (they are on different servers) appear to have
the same versions installed. Both the SSRS and SSAS servers are running SQL 2012 SP2.
Any suggestions would be appreciated as I haven't had much success locating the cause.Hi Tymbow,
Per my understanding that you got the error message in the step3 when creating the DataDriven Subscription, right?
I have checked the error message and as you have mentioned that other reports which have the same connection string works fine in report server, so the issue can be cause by the query you are using in the step3 is not correct, sometimes although it
will work in database or in the desginer, it will have some limitation in the commend query.
Please provide the connection string you are using and also the commend query to help us better understanding of the issue.
If you still have any problem, please feel free to ask.

I am not getting why it is happening .. hope this is enough to understand issue
Dilip Patil..Make sure you have enough space for ReportserverTempDb and SQL Server TempDB for getting the data from respective database.
As per the errors seems query has issues with blockings.
Transaction (Process ID 90) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
Please verify the query in SSMS and make sure the results are appearing smoothly.

Data-driven Subscription doesnt send out an email but job history shows its successfull
Hi All
Please give me some advice about this Data-driven Subscription runs every hour misses out once or twice a day, but the subscription job history shows it ran sucessfull but it doesnt trigger the e-mail out.
Is there a way to check on subscription logs that SSRS has triggered the report out to the e-mail server.
Is there a way to add add logs for the e-mail part to make sure it has sent out the email ?
Nothing in the E-mail server logs to show this report email was requested / delivered / rejected by it.
So - Kindy advice me how can I proceed my findings on this.
Thanks a lot in advance.Report Server Service logs below

Pause Issue:-- SSRS Data Driven Subscription
I have setup SSRS data driven subscription and it run successfully without any error but something that i noticed, i wanted to know why it happened and how can we prevent?
1. when i check status bar every 10 sec, after generating some reports, its stays at some count numbers and dont move and suddenly it will move and finish the process without any errors, why pause?
2. if my data driven subscription run successfully for 1900 reports and fail for 100 reports, how can i manually find 100 errored report and run it manually?
3. In the database, is there any way we can get detailed about processing or error info other than log tables in reportserver db?
Thank you for help!Hi SQL—DBA,
1. when i check status bar every 10 sec, after generating some reports, its stays at some count numbers and dont move and suddenly it will move and finish the process without any errors, why pause?
In Reporting Services, status messages within the subscription page are updated when the subscription is scheduled to process. If the trigger never occurs, the status message will not be updated. For more information, please refer to this article:
Monitor Reporting Services Subscriptions.
2. if my data driven subscription run successfully for 1900 reports and fail for 100 reports, how can i manually find 100 errored report and run it manually?
In this scenario, you can run the query to find the failed subscription information from the database which we have setup for Reporting Services. Please refer to this article:
SSRS Failed Subscription Notifications.
Then you can execute the code with jobstep command to find the corresponding SQL Agent Jobs for failed subscription, then execute the job to send the email again. Please refer to this article:
Re-running SSRS subscription jobs that have failed.
3. In the database, is there any way we can get detailed about processing or error info other than log tables in reportserver db?
In this scenario, you can check the subscription table from the ReportServer database to find the status and error message of subscriptions. If we want to trouble subscriptions, I would like to suggest you use the Reporting Services Trace Log File. For more
information, please refer to this article: Troubleshooting Subscriptions: Part II, Using the Reporting Services
Trace Log File.
If you have any question , please feel free to ask.
Best regards,

SSRS 2005 - Data Driven Subscription
Hi ,
On my report manager - 2005, I have one report which has only one parameter (Seller) and this is a single select parameter (NOT multiple selects)
I want to create a data driven subscription which will send automatic Email to specified users on a weekly basis (every Friday morning)
The only condition while sending excel formatted email is that, it should select some specific values only for this parameter "Seller"
Example, it should send email to users only for Seller = A, B, and C and it should NOT send data for all other sellers
Can you pl explain each step to do this ?
RegardsHi UltraDev,
If I understand correctly, you want to use data-driven subscription to send corresponding report to specific Seller. Please refer to the following steps:
Click New Data-driven Subscription icon in the Subscriptions dialog box of the report.
Select E-Mail option of Specify how to recipients are notified, and select “Specify a shared data source”. Next.
Select the corresponding datasource. Next.
Add query in the blank. It is related to the recipient. You can refer to the following code:
Select ‘[email protected]’ as SellerAddress, ’A’ as Seller
Union
Select ‘[email protected]’ as SellerAddress, ’B’ as Seller
Union
Select ‘[email protected]’ as SellerAddress, ’C’ as Seller
In the Step4 page, select “Get the value from the database” below “To”.
Then, we can select the Seller field as the specify value which is only with A, B, C three values.
In the Step5 page, we can configure the parameter values.
After that, we can configure the schedule of the subscription.
There is an article about how to Creating a Data-Driven Subscription, you can refer to it.

How would I implement something similar to SSRS data driven subscriptions in CRM 2015 Online?
Requirement: Generate Report and send specific pricing information to a list of contacts based on field value.
I'm new to CRM, but am well versed in SSRS and I'm looking to understand:
1. Is it possible to create something like a data driven subscription in CRM?
Everything I've looked at is from years ago, and I'm just looking for some high level directions I can pursue in order to fulfill this requirement.
Thanks!Did you notice the difference between your image and theirs. Their image has a coordinate grid. This coordinate grid can be used to determine size, location of pixels, etc...
If you add a grid, when you process the image, find the grid, then find the coordinate markings, then find the pixels in relation to these coordinate marking creating an internal buffer of the image.
ie: have 0=white 1=black 2=grid 3=coordinate marking and make an internall representation of your image
011002300000
001002201000
011102300010
323232232323
222222222222
001002310000
000102200100
010002301000
Just an idea, but look into the coordinate grid it may be the key to why they can process their image.
