I am importing a CSV file in SSIS having many string columns. I have set column width more than the maximum length, but still I am getting below errors
[Input CSV File [114]] Error: Data conversion failed. The data
conversion for column "Functionality" returned status value 4 and
status text "Text was truncated or one or more characters had no match
in the target code page.".
[Input CSV File [114]] Error: The "Input CSV File.Outputs[Flat File
Source Output].Columns[Functionality]" failed because truncation
occurred, and the truncation row disposition on "Input CSV
File.Outputs[Flat File Source Output].Columns[Functionality]"
specifies failure on truncation. A truncation error occurred on the
specified object of the specified component.
[Input CSV File [114]] Error: An error occurred while processing file
"D:\Prateek\SSIS_UB_PWS\January.csv" on data row 236.
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED. The
PrimeOutput method on Input CSV File returned error code 0xC0202092.
The component returned a failure code when the pipeline engine called
PrimeOutput(). The meaning of the failure code is defined by the
component, but the error is fatal and the pipeline stopped executing.
There may be error messages posted before this with more information
about the failure.
As a work around, I have set values to 500 or 1000 and now it is allowing me to continue, but the actual length is in double digit.
Kindly suggest what could be the possible error.
Check , what is the value of the column 'Functionality' at row number 236. And then , verify what is allowed. In the advanced editor of the source, you can increase the length(if there are not any special characters) if you are loading data into a table
Truncation warning appears when your source column length is bigger than destination column length, so it'll truncate the source value to fit into its destination. Could you share with us the length of the column length, and the length of destination column?
I got the error, sorry for my bad understanding of issue.
Actually one of the column is having multiple commas (,) in data and that was getting into other columns (Text delimiter was set to ). Hence I was getting bigger values than expected in other columns as well.
Thanks for you help!

For the life of me, I cannot seem to get past the following error:
Error: 0xC020901C at Import Data - APA, APA Workbook [2]: There was an error with APA Workbook.Outputs[Excel Source Output].Columns[Just] on APA Workbook.Outputs[Excel Source Output]. The column status returned was: "Text was truncated or one or more characters had no match in the target code page.".

I have an SSIS package that is trying to load data from an Excel file into a SQL Server table. I understand SSIS takes a "Snapshot" of the data and uses this to build the column sizes. My database column for this column is: nvarchar(512).
So some things I have done to try and rectify this are as follows:
Added "IMEX=1" to the extended properties of the Excel Connection string
Created an Excel file with 10 rows and each row has 512 characters in this "Just" column so that SSIS will recognize the size
Went into the Advanced Editor for the Source, then "Input and Output Properties". Then went to the Just column and changed DataType to "Unicode String [DT_WSTR] and changed the Length to 512
After I did the above, I ran the code and the 10 rows of data were imported with no issue. But when I run it against the real Excel file, the error appears again.
I have found that if I add a column to find the character length of the column, then sort by that, putting the largest first, the code works. But if the file is as sent by the user, it errors out
I would appreciate any help on how to solve this, as all of my Google searches state the above would work, but unfortunately it is not.
First of all, when the column isn't NULL, it is successfully able to do the conversion. The destination DB field accepts null values.
In my Data Conversion step I have set the Input Column's DataType to numeric[DT_Numeric], Precision 18, and Scale 2.
I have two rows in my CSV, the first row does not contain any NULLS.. and if I execute that it's a success. However when I add a 2nd row with a NULL value in that column it fails and I get these errors:
[Data Conversion [2]] Error: Data conversion failed while converting column "Column 24" (138) to column "DbColumn24" (22). The conversion returned status value 2 and status text "The value could not be converted because of a potential loss of data.".

I do not think I need a Derived Column step before data conversion step to handle any nulls because the DB column accepts nulls.
Since your source is a CSV, I doubt that you actually have any NULL values in your source at all. More likely you have empty string values, which are not the same as NULL, and empty strings cannot be implicitly converted to Decimal. You will probably have to explicitly convert the empty strings to NULL in an expression.
The work around would be
1) First convert the column to varchar/nvarchar
2) Use derived column to convert to Decimal
3) Map the converted column to destination
My DFT fetches data from an SP. It is followed by a conditional split to split dataset into 5 parts based on a column value. The sub-datasets are then written into an excel file. All 5 outputs write into the same excel file, But different tabs. I have explicitly mentioned the Column range and starting row for the data to be written. Data load into the Excel file fails with the following error.

The most frustrating part is that the Excel destinations fail at random. Lets name them as A,B,C,D and E. During 1st run A will fail and the rest will write data successfully. During the 2nd run, A will succeed but C and E will fail and so on.
Every time the Excel Dest fails, data is still written in that particular tab. But I can see some blank rows in the dataset. I added a data viewer before each Excel Dest and the data looks correct. There are no blank rows either. number of rows per data set are fixed (18).
I am using a template every time which has only Column headers.
4 columns have datatype of nvarchar with max data length of around 50. 12 columns are Numeric(38,2).
Any help would be very much appreciated.
Thanks,
Gaz
Reorganize the package so that the writes will occur sequentially. The error you are seeing is the result of concurrency issues. You can't write to the same file in 5 different places at once. You have to do let each write finish before the next one starts.
Here it is below a full dump of the SSIS complains. Please note that I imported the same data in the destination table by using a different tool already and everything is looking perfectly, I suppose that means the schema of the destination table is correct. What do I have to do here to actually use SSIS (the entire process is automated, I did it manually now but that is not acceptable in long term...)

Your data contains unicode characters i guess and the destination is varchar(23). Try to change it to nvarchar(23) and then import ?
Use utf 8 and you will be fine. That is in the first screen after the welcome in the import export tool. That displays properly the accents.
I have an SSIS package I am using to load a Fixed Width flat file. I have put in all the column lengths and have two packages against similar files working correctly. The third however keeps throwing the following error:

After doing some testing this happens for any column I have the is using the DT_I4 Data Type and has a blank in the column. I was going to try using a derived column, but this seems to fail for some of the columns even if I change them to a string data type to handle the blank as a NULL and then do a conversion to an INT later in the data flow.
In the source and the destination task I have the Retain NULL values checkbox ticked however this hasn't changed anything.
Any suggestions on handling this error where INT seems to fail at converting a blank to a NULL?
DT_I4 maps to a four byte signed integer in SSIS.
You were on the right track with your derived column. You just need to add the right expression.
You can try this expression:
ISNULL([Line Number]) ? "0":[Line Number]

I ended up using the approach from this blog post:
http://www.proactivespeaks.com/2012/04/02/ssis-transform-all-string-columns-in-a-data-flow-stream/
to handle all of the null and blank columns via a script task and data conversion.
