SAP S/4HANA Error 5436: MIME Type Mismatch
Description
This error indicates that the content type (MIME type) of data being processed or uploaded does not match the expected format within SAP S/4HANA. It typically occurs when the system anticipates a specific data format (e.g., text/plain, application/xml) but receives data in an incompatible type, preventing the operation from completing.
Error Message
ERR_TEXT_FCA_MIME_TYPE_MISMATCH
Known Causes
4 known causesIncorrect File Upload Format
Attempting to upload a file with a MIME type different from what the SAP S/4HANA system expects for that specific upload function.
Misconfigured Data Integration
Data sent from an external system via an API or interface has an incorrectly declared MIME type in its header, causing a mismatch with the receiving SAP S/4HANA endpoint.
Manual Data Entry Discrepancy
In some specific text fields, manually pasted or entered content might internally be interpreted as a different data type than what is permitted for that field, triggering the error.
Corrupted or Malformed Data
The data itself is corrupted or improperly structured, leading the system to misidentify its MIME type or fail to process it as the expected format.
Solutions
4 solutions available1. Verify and Correct Document Attachment MIME Type easy
Ensures the MIME type of the uploaded document matches the expected type for S/4HANA attachments.
1
Identify the specific business object and document attachment that is causing the error. This is usually visible in the application log or the error message itself.
2
Access the document attachment. The method to do this depends on the S/4HANA application. It could be through a Fiori app, SAP GUI transaction, or a custom development.
3
Examine the properties of the document attachment to determine its actual MIME type. This might require downloading the file and checking its properties or using a tool that can inspect file metadata.
4
Compare the actual MIME type with the expected MIME type for the attachment in S/4HANA. The expected MIME type is often determined by the business process or configuration. Common examples include 'application/pdf' for PDFs, 'image/jpeg' for JPEGs, 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet' for XLSX files.
5
If there is a mismatch, re-upload the document with the correct file type or convert the existing document to the appropriate format before re-attaching. For example, if an Excel file was saved as a .txt but intended as .xlsx, convert it back to .xlsx.
2. Check SAP Gateway (OData Service) MIME Type Configuration medium
Validates that the OData service handling attachments in S/4HANA is correctly configured for MIME types.
1
Identify the OData service that is being used to upload or process the document attachment. This can often be found by tracing network requests in the browser's developer tools when the error occurs, or by consulting the application's technical documentation.
2
Access the SAP Gateway system or relevant S/4HANA backend system. Navigate to transaction `SEGW` (SAP Gateway Service Builder) or use the relevant Fiori app for OData service management.
3
Locate the specific OData service and examine its configuration. Pay close attention to the entity sets and operations related to attachments. Look for any properties or annotations that might define or restrict the allowed MIME types.
4
If custom logic is involved in handling attachments via the OData service (e.g., custom ABAP code), review that code for any explicit checks or hardcoded MIME type validations that might be incorrect.
5
Ensure that the OData service is configured to accept the MIME type of the document being uploaded. This might involve updating service metadata or ABAP code if custom validation is in place.
3. Review and Adjust SAP Document Management System (DMS) Settings medium
Verifies and corrects configuration within SAP's Document Management System if it's used for managing attachments.
1
Determine if SAP's Document Management System (DMS), often accessed via transactions like `CV01N`, `CV02N`, `CV03N`, or integrated into S/4HANA applications, is being used for the attachments.
2
Access the DMS configuration in the SAP system. This typically involves transactions like `OAC0` (Content Repositories) and `OACT` (Document Types).
3
Navigate to the relevant Document Type configuration. Within the Document Type settings, there's often a section for 'File Extensions' or 'MIME Types'.
4
Check if the MIME type of the problematic attachment is explicitly listed or allowed for the Document Type being used. If not, add the correct MIME type and its associated file extension.
Example: For PDF files, ensure 'application/pdf' is associated with '.pdf'.5
Ensure that the content repository configured for the DMS is correctly set up and accessible. While less directly related to MIME type mismatch, repository issues can sometimes manifest in unexpected ways.
4. Analyze Application Logs and Trace for Detailed Error Information easy
Extracts granular details from system logs to pinpoint the exact cause of the MIME type mismatch.
1
Access the application log in S/4HANA. This can be done via transaction `SLG1` (Application Log).
2
Enter the relevant object and subobject for the application experiencing the error. Common objects related to attachments or document management might include `BC_SRV_RM` (Record Management), `FDT` (Forms), or specific application components.
Object: BC_SRV_RM
Subobject: DOCUMENT3
Execute the log analysis and filter by the error message code `ERR_TEXT_FCA_MIME_TYPE_MISMATCH` or related keywords. Look for timestamps that correspond to when the error occurred.
4
Examine the detailed log entries. They often contain information about the file name, the attempted MIME type, the expected MIME type, and the context of the operation (e.g., the transaction or Fiori app involved).
5
If the application log is not sufficient, consider using the SAP Gateway Client (`/IWFND/GW_CLIENT`) or browser developer tools to trace the OData requests and responses. This can reveal the exact MIME type being sent by the client and how it's being interpreted by the server.
