SSIS 469 Error Easy Fix for the Most Common Data Flow Problem
SSIS 469 is a specific error code that appears in Microsoft SQL Server Integration Services (SSIS). This error shows up when there is a problem with the data that SSIS is trying to move, convert, or process. SSIS 469 is most often caused by a mismatch between the expected data type and the actual data provided.
This article will explain what SSIS 469 means, why it happens, how to fix it, and how to prevent it in the future — using clear and simple language.
What Is SSIS 469?
SSIS 469 is an error that means there is a data type mismatch during a task in SSIS. It usually appears when data is being transferred from one source to another, and the format or type of that data does not match what the destination expects.
For example:
- If SSIS tries to send text (like “ABC”) into a column that only accepts numbers, it may cause SSIS 469.
- If SSIS tries to convert a value into a format that is not allowed, this error can also appear.
SSIS 469 acts like a warning that tells you: “Something is wrong with the format or type of this data.”
Why Does SSIS 469 Happen?
SSIS 469 usually happens because of one or more of the following reasons:
- Wrong data type in a column (e.g., trying to insert text into a numeric column).
- Unexpected null values in places where nulls are not allowed.
- Invalid conversions during data processing (like trying to convert a string to a date, but the string is not in a date format).
- Incorrect data mapping between source and destination fields.
- Poor input data quality, such as special characters or empty fields.
This error stops the SSIS package from running because the data is not acceptable in its current form.
How to Detect SSIS 469
When SSIS 469 occurs, it usually shows up in the error output log or in the execution results. The message may look like this:
“SSIS Error Code DTS_E_PROCESSINPUTFAILED. The ProcessInput method on component failed with error code 0xC0209029. The identified component returned an error from the ProcessInput method.”
This message can also include the row number, column name, and the type of conversion that failed. That information helps locate the problem.
How to Fix SSIS 469
Solving SSIS 469 involves finding and correcting the data issue that caused the mismatch. Here are the most common ways to fix it:
Match Data Types
Check the source and destination data types. Make sure they are the same.
For example:
- If one side is
INT(integer), the other should not beVARCHAR(text). - If one side is
DATE, the input must be in a correct date format likeYYYY-MM-DD.
Use Data Conversion Task
In SSIS, use the Data Conversion task to convert values to the correct type before they are sent to the destination.
Example:
- Convert a
stringinto anintegersafely - Change
textdates like “01/01/2025” intoDATEformat
Add Error Handling
Use Error Output in data flow components. This captures rows that fail and sends them to a different path. You can save these rows and review them later to find out why they failed.
Clean the Data
Check for:
- Extra spaces
- Letters in number fields
- Symbols that don’t belong (like
#,$, etc.) - Missing or blank values
Use a Derived Column or a Script Component to fix or skip the bad data.
Review Column Mapping
Make sure each column from the source is mapped correctly to the destination column. Wrong mapping can send the wrong type of data to the wrong column.
Example Scenario of SSIS 469
Imagine you are importing customer data from an Excel sheet.
- The Excel file has a column called
Age, and it contains values like: “30”, “twenty-five”, “40” - In your SQL Server table, the
Agecolumn is set to only accept numbers (INT)
When SSIS tries to load the word “twenty-five” into a number column, it will show SSIS 469 because text cannot be converted into an integer.
To fix this:
- Remove or correct the wrong value
- Convert the value into a valid number before sending it to SQL
How to Prevent SSIS 469
To avoid getting SSIS 469 in future runs, follow these best practices:
Validate Source Data
Before using SSIS, check your source files for:
- Wrong formats
- Blank values
- Inconsistent data types
This reduces the chances of errors.
Profile the Data
Use the Data Profiling Task in SSIS to scan and understand the data. It helps find bad values, nulls, and wrong formats before they cause problems.
Use Try-Catch Logic
In more advanced SSIS packages, you can build try-catch-style flows to catch errors without stopping the entire package. This lets good data continue to flow, even if bad rows are skipped.
Test with Sample Data
Always test your SSIS package with a small amount of data. This helps find errors early before running the full job.
Keep Packages Documented
Write clear notes about what each task does. If an error happens, you or another team member will be able to fix it faster.

Business Impact of SSIS 469
Even though SSIS 469 is a technical error, it can have a real impact on business operations:
- Reports may show incorrect data
- Business decisions may be based on incomplete or wrong data
- Data warehouses may get filled with broken or missing information
- Delays in data processing can affect timelines
Fixing and preventing SSIS 469 ensures data is reliable, clean, and ready for business use.

Summary
SSIS 469 is a common but important error in Microsoft SSIS. It happens when there is a data mismatch — usually between what the system expects and what it actually gets. The error message points to the part of the package where this mismatch occurred.
You can fix SSIS 469 by:
- Matching data types
- Cleaning the source data
- Using the data conversion task
- Mapping columns correctly
- Using error outputs for handling bad data
By understanding and handling SSIS 469 properly, you make sure your data flows smoothly, your jobs run successfully, and your results are always correct.
