SAP S/4HANA Error 339: Invalid SQL Number Format
Description
Error 339, ERR_SQL_INV_NUMBER, signifies that a numerical value provided within an SAP S/4HANA transaction or process is not recognized as a valid number by the underlying SQL database. This usually happens when non-numeric characters are entered into a numeric field, or when the format of a number (e.g., decimal separator, thousands separator) does not conform to the expected database standard.
Error Message
ERR_SQL_INV_NUMBER
Known Causes
4 known causesIncorrect Manual Data Entry
A user has manually entered non-numeric characters (e.g., letters, symbols) into a field specifically designated for numerical values.
Data Import/Integration Mismatch
Automated data imports or integrations are supplying data with an invalid numeric format or non-numeric values to fields expecting numbers.
Locale/Regional Format Conflict
The number format (e.g., decimal point vs. decimal comma) used in the input does not align with the system's or database's expected regional settings.
Corrupted Data or Conversion Issue
An internal system process or conversion attempt is generating or processing data that cannot be interpreted as a valid number.
Solutions
3 solutions available1. Identify and Correct Invalid Data in Input Fields easy
Locate and fix non-numeric characters in fields expecting numerical input within SAP S/4HANA transactions.
1
Reproduce the error by performing the transaction or action that triggers error 339.
2
Carefully examine all input fields on the screen, paying close attention to fields that are expected to contain numbers (e.g., quantities, prices, account numbers, document numbers).
3
Look for any non-numeric characters such as letters, special symbols (e.g., commas, periods where not expected), or extra spaces. Sometimes, leading/trailing spaces can cause this issue.
4
Correct any identified invalid characters. Ensure that only valid numeric characters are entered. For example, if a comma is used as a decimal separator, ensure it's in the correct locale format.
5
Re-attempt the transaction. If the error persists, review other fields or consider the next solution.
2. Investigate Custom Development for Data Type Mismatches medium
Analyze custom reports, interfaces, or enhancements for incorrect data type handling when interacting with numerical fields.
1
Identify any custom ABAP programs, reports, interfaces (e.g., RFC, IDoc, OData), or user exits/enhancements that are executed as part of the process leading to error 339.
2
Review the ABAP code for data assignments to database fields or function module parameters that expect numerical types (e.g., `I`, `P`, `F`).
DATA: lv_amount TYPE p DECIMALS 2.
DATA: lv_input TYPE string.
* Incorrect assignment if lv_input contains non-numeric characters
lv_amount = lv_input.
3
Ensure that any data being moved into numerical fields has been properly validated and converted. Use ABAP functions like `CONV`, `STRLEN`, `FIND`, `OFFSET` to validate and clean string inputs before assigning them to numerical types.
DATA: lv_amount TYPE p DECIMALS 2.
DATA: lv_input TYPE string.
IF lv_input IS NOT INITIAL.
TRY.
lv_amount = CONV decfloat( lv_input ).
CATCH cx_sy_conversion_error.
" Handle conversion error, e.g., set to 0 or raise error
MESSAGE 'Invalid number format in input' TYPE 'E'.
ENDTRY.
ENDIF.
4
Pay special attention to data coming from external systems or user input, as these are common sources of invalid number formats.
5
Test the corrected custom code thoroughly in a development or quality environment before deploying to production.
3. Verify System Locale and Number Formatting Settings medium
Check SAP system's number formatting settings to ensure consistency between user input and system expectations.
1
Log in to the SAP S/4HANA system as the user experiencing the error.
2
Navigate to transaction `SU01` (User Maintenance).
3
Enter the user ID and click 'Display'.
4
Go to the 'Defaults' tab.
5
Check the 'Decimal notation' and 'Date format' fields. Ensure they align with the expected number and date formats for the user's region.
6
If these settings are incorrect, modify them to the appropriate format (e.g., '1.234,56' for European locale, '1,234.56' for US locale).
7
Save the changes and ask the user to log out and log back in.
8
Attempt the transaction again.
