Description

This error indicates a failure in handling UChar32 (Unicode 32-bit) characters within SAP S/4HANA. It typically occurs when the system encounters issues processing or appending complex or non-standard Unicode characters, often related to character encoding mismatches or invalid input data during text operations.

💬

Error Message

ERR_TEXT_COMMON_U16_APPEND_FAILED

🔍

Known Causes

4 known causes

⚠️

Character Encoding Mismatch

Data input or system settings use incompatible character encodings, causing failure when processing Unicode characters.

⚠️

Invalid Unicode Input

Attempting to process text data containing malformed, unsupported, or non-standard Unicode characters.

⚠️

System Configuration Limitations

SAP S/4HANA or underlying database/OS character set configurations do not fully support the required Unicode range.

⚠️

Data Integration Encoding Issues

Character set conversions fail during data import, export, or integration with external systems.

Solutions

3 solutions available

1. Validate and Correct Character Encoding in Data medium

Ensures data integrity by identifying and rectifying incorrect character encodings that cause UChar32 processing failures.

1

Identify the specific table and field(s) causing the UChar32 processing failure. This often requires analyzing the SAP application logs (e.g., SM21, ST22) or database trace files to pinpoint the exact location.

2

Use SAP's built-in tools or custom ABAP programs to scan the identified fields for characters that are not compatible with the expected UTF-32 encoding. Common culprits include legacy characters or improperly converted data.

Example ABAP snippet to check character validity (conceptual):

DATA: lv_string TYPE string.
DATA: lv_char TYPE c LENGTH 1.
DATA: lv_valid TYPE abap_bool.

LOOP AT lt_data ASSIGNING FIELD-SYMBOL(<fs_data>).
  lv_string = <fs_data>-your_field.
  DO strlen( lv_string ) TIMES.
    lv_char = lv_string+sy-index-1(1).
    CALL FUNCTION 'CL_ABAP_STRING_UTILITIES=>IS_VALID_UTF8'
      EXPORTING
        string = lv_char
      IMPORTING
        result = lv_valid.
    IF lv_valid = abap_false.
      " Log or handle invalid character
      MESSAGE e001(00) WITH 'Invalid character found:' lv_char.
    ENDIF.
  ENDDO.
ENDLOOP.

3

Once invalid characters are identified, use appropriate data cleansing techniques. This might involve replacing invalid characters with placeholders, deleting them if they are non-essential, or converting them to a valid UTF-32 representation. This is typically done via ABAP programs or data migration tools.

Example ABAP snippet for replacement (conceptual):

DATA: lv_string TYPE string.
DATA: lv_char TYPE c LENGTH 1.
DATA: lv_replacement TYPE string VALUE '?'. " Or other suitable replacement

LOOP AT lt_data ASSIGNING FIELD-SYMBOL(<fs_data>).
  lv_string = <fs_data>-your_field.
  DO strlen( lv_string ) TIMES.
    lv_char = lv_string+sy-index-1(1).
    CALL FUNCTION 'CL_ABAP_STRING_UTILITIES=>IS_VALID_UTF8'
      EXPORTING
        string = lv_char
      IMPORTING
        result = lv_valid.
    IF lv_valid = abap_false.
      REPLACE lv_char WITH lv_replacement IN lv_string.
    ENDIF.
  ENDDO.
  <fs_data>-your_field = lv_string.
ENDLOOP.

After data correction, re-run the process that triggered the error to confirm the issue is resolved.

2. Review and Adjust Database Character Set Configuration advanced

Ensures the underlying SAP HANA database character set is correctly configured to support UTF-32 processing.

1

Access the SAP HANA database administration tools (e.g., SAP HANA Studio, SAP HANA Cockpit).

2

Navigate to the database's system properties or configuration settings. Look for parameters related to character set or collation.

3

Verify that the database is configured to use a character set that fully supports UTF-32. For SAP S/4HANA, this typically means ensuring UTF-8 or a compatible encoding is in use. Consult SAP Notes for specific recommendations.

Example SQL query to check current character set (may vary depending on HANA version and access):

SELECT * FROM SYS.M_DATABASE_CONFIGURATION WHERE KEY = 'unicode_encoding';

4

If the character set is not set correctly or is found to be incompatible, consult SAP Notes and follow the documented procedures for changing the database character set. **Caution:** Changing the database character set is a significant operation that requires careful planning, downtime, and potential data migration or conversion. Always perform this in a test environment first.

5

Restart the SAP HANA database and the S/4HANA application services after any character set configuration changes.

3. Apply SAP Notes and Kernel Patches medium

Addresses known issues and bugs related to character encoding processing by applying relevant SAP updates.

1

Access the SAP Support Portal (launchpad.support.sap.com).

2

Search for SAP Notes related to 'S/4HANA Error 5200', 'UChar32 Processing Failure', 'ERR_TEXT_COMMON_U16_APPEND_FAILED', and character encoding issues in your specific S/4HANA version.

Search terms: "S/4HANA 5200 UChar32", "ERR_TEXT_COMMON_U16_APPEND_FAILED SAP Note", "UTF-32 processing error HANA"

3

Review the identified SAP Notes for recommended solutions, which may include applying specific kernel patches, ABAP corrections, or configuration changes.

4

If a relevant SAP Note is found, follow the instructions precisely to download and apply the necessary patches or corrections using SAP's standard tools (e.g., SNOTE, SUM).

5

After applying the updates, restart the SAP S/4HANA application servers and test the process that was failing.
