Mid function is not working in SSRS...

I tried to sub string SSRS data set field to have new calculated field. But when I see the output I did not get the desired one and original string value was there. Also I did not get any error message too.
The issue was with the Start Position. I provided the start position as 0. But the correct start position should be greater than 0. When I changed it to 1, I got the correct output. The correct formula is Mid("StringVal",1,6). It gives the first six characters of the provided string.

Error in PerformancePoint 2010...

While trying to create a new data source in PerformancePoint 2010 Dashboard Designer, I got an error message as This data source cannot be used because performancepoint services is not configured correctly. The error message is shown in the below figure. I got it after providing the server and while trying to expand the available databases.

This is because that the PerformancePoint is not configured correctly. While configuring PerformancePoint, we need to configure Unattended Service Account. The error occurred due to that account is not configured correctly.
To fix that issue we need to re-configure that unattended service account correctly.
To configure unattended service account, you need a Secure Store Service Key.

Steps to fix the above issue are
  • To generate a secure store service key, go to SharePoint 2010 Central Administration →Application Management → Manage Service Applications → Secure Store Service
  • Then click on Generate New Key
  • Once that is done go to the SharePoint 2010 Central Administration → Application Management → Manage Service Applications → PerformancePoint Service Application
  • Then select Performance Point Service Application Settings
  • In the Unattended Service Account section, enter the user name and password for the account that you want to use as the unattended service account. This is the account that PerformancePoint Service will use to connect to the data source unless you use Per User Identity.
  • Click Ok and if the provided account details are correct, it will be successful.
  • Then go to the Dashboard Designer and try to create the data source again and you will not get that error message.

An error occurred during local report processing...

I modified an existing report by deleting some dataset  fields and adding new ones. Then in the report I removed the deleted fields from each reference and added the required new ones. But when I tried to preview the report, I got the report processing error as
The Hidden expression for the grouping "Group1"  refers to the field "Field1". Report item expressions can only refer to the fields within the current data scope or, if inside an aggregate, the specified dataset scope...

I checked the report and already the reference for Filed1 is deleted from all the locations. But finally I was able find the reason. Error was in the Static Hidden Groups.
In some of the those hidden static groups, Field1 is used. To view those groups, select the Tablix and click on the Down arrow in the bottom right hand corner as shown in the below figure and select Advanced Mode.

Then you will those Static groups as in the above image. In that check the relevant static groups for the group mentioned in the error message. You will be able to find that the Field1 is still used in that group. Remove or change Field1 from that and try to preview the report. If no other static groups use any of the deleted fields, you will be able to view the report successfully.
