MS SSIS 2005

The component failed because truncation occurred, and the truncation row disposition on "output column " specifies failure on truncation. A truncation error occurred on the specified object of the specified component.

common error messages when dealing with SSIS. and you google alot to know the answer. some people advise to user derived columns!

but the problem is when initiating the data source itself.

So the answer is pretty simple:

for the field that produce this error, on the output field for this field make it not fail the componenet but rather ignor this error.

SQL Server Analysis Server Exploring the studio and troubleshoot

Now we made a cube that wrap all the dimensions and facts we want to analyze in our scope.

The First tab when clicking on the cube is the "cube structure", where you can see the cube structure and modify the relationships and dimensions the cover the cube from the business perspective. you can add a hierarchy, or delete it. you can add new measure, new dimension from the data source view.

The "Dimension usage" tab. Where you can link those dimensions with measures.

The "Calculations" tab . where you can add new calculations to help you to more analyze the data.

The "KPI" tab . where you can add your indicators to see if the data is going fine or there exists something wrong. here you have to know some MDX query language.

The "Perspectives" tab. where you can add perspectives to the cube on each one you will specify the dimensions and the measures related to it.

The Last tab is the "Browse" tab. where you can browse the cube. to do it you have to deploy the cube, and to do so. you have to right click on the project name->click on "properties"-> then change the path of the deployment server. then click ok. then click deploy.

Clarification:

After making the KPI's you may want to see them. There are many tools enable you to browse the cube and manipulate it like: Excel, ProClarity owned by Microsoft now, business Object.

in all of those you may not see the KPI's as you saw them in the Visual studio. Why? because this is an owned shapes by visual studio, you may see this KPI's with different shapes and colors. so according to the viewer, you will design the KPI indicator shape to fit the viewer. Otherwise you have to develop this viewer to the target tool.

Troubleshoot:

"A connection cannot be made. Ensure that the server is running. "

this error message occurred for the impersonation of the SQL server instance.
the solution is:
1- in the project properties, deployment section, modify the server to the SQL server 2005 instance.
2- in the data source double click, in the impersonation tab, select the "use the service account".

Now you have ended the cube and we wanna view it.
The next time we will explore the Reporting Service structure.

SSIS Troubleshoots and Bugs

ah, Now you face some troubles, before we proceed, you have to install SQL Server 2005 SP2. This Service Pack fixes alot of bugs. and also generate another. Anyway, after you install it you might face one or more of the following:

1- Could not add the DataFlow task?

check the SQL Server running service. Open the "Administrative Tools->Services-> SQL Server Integration Services " and change the logon to "Local System Account", then restart the service.

also check that most of the services uses the "Local System Account", not the network account.

this problem occurs when you are in a network, the Sql server uses this account as a general user to work with. But this is wrong

2-Error [OLE DB Destination [2923]]: The column cannot be processed because more than one code page (1252 and 1256) are specified for it.

this happens with the OleDB module that transfers the data into the destination DB.

the problem is the code page is differ, the problem has two solutions:

a. put a "derivative column", and convert all columns code page to the DB server code page.
b. go to the destination [Ole Db Destination] and check "always use default code page" to true.

3- I drawn my transformation but when I replaced it I got error?


A general bug. when you drag a component fromthe toolbox and drop it into the board. It takes a number. if this component generates an elements like the datasources, each element took a number. the problem is this number is unique. and cannot be reallocated to another unit.

the solution redraw the package....

4- Fuzzy lookup somehow took so long and other times does not take time?

the reason is simple, your data contains duplicate rows.

the Fuzzy lookup component get the data, if the data duplicated it builds another indeces. and allocate it to the rows. the do the fuzzy operation. when you try to apply the fuzzy algorithm to duplicated rows, it doubles the effort for ignoring the result of this row values.
