Error Message
ERR_TEXT_FCA_UNSUPPORTED_DOCUMENT_TYPE
Known Causes
3 known causesMismatched File Format
The actual file format (e.g., PDF, XLSX) of the submitted document differs from the format expected by the SAP S/4HANA process or field.
Unconfigured Document Category
The specific business document category (e.g., invoice, purchase order, contract) is not properly defined or enabled for the relevant transaction in SAP S/4HANA.
External System Incompatibility
An integrated external system is attempting to send documents with a type or structure that SAP S/4HANA is not configured to accept for the specific interface.
Solutions
3 solutions available1. Verify and Correct Document Type Configuration in FI-CA medium
Ensures the document type used in the transaction is correctly configured and active within SAP S/4HANA's Financial Accounting Contract Accounts Receivable and Payable (FI-CA) module.
1
Access the SAP S/4HANA system and navigate to the transaction where the error occurs. Note the document type being used.
2
Execute transaction code `SPRO` to open the SAP Customizing Implementation Guide.
3
Navigate to: `SAP Customizing Implementation Guide` -> `SAP NetWeaver` -> `General Settings` -> `Document Types` -> `Define Document Types`.
4
In the 'Define Document Types' screen, search for the document type identified in step 1. Verify its existence and ensure it is not marked as 'Inactive' or 'Obsolete'.
5
If the document type is missing or incorrectly configured, create a new document type or modify the existing one to match the requirements. Pay close attention to the 'Document Type' field, 'Description', and any relevant settings for FI-CA integration.
6
Save the changes. If creating a new document type, ensure it's assigned to the correct company code and relevant controlling objects.
7
Re-execute the transaction that previously failed to confirm the error is resolved.
2. Check FI-CA Integration Settings for the Document Type medium
Confirms that the document type has the necessary integration settings enabled for FI-CA processes, such as account determination and posting rules.
1
Identify the specific FI-CA process or module associated with the transaction causing the error (e.g., invoicing, payments, dunning).
2
Execute transaction code `SPRO`.
3
Navigate to: `SAP Customizing Implementation Guide` -> `SAP Customizing Implementation Guide` -> `Cross-Application Components` -> `SAP Business Partner` -> `Business Partner` -> `Basic Settings` -> `Account Grouping` -> `Define Account Grouping` (This is a general example; the exact path might vary based on the FI-CA sub-module).
4
Alternatively, navigate to the specific FI-CA configuration area relevant to the transaction. For example, for invoicing, this might involve `SAP Customizing Implementation Guide` -> `Financial Accounting (FI)` -> `Contract Accounts Receivable and Payable` -> `Basic Functions` -> `Posting and Document Handling` -> `Define Document Types` (This might be a duplicate of the previous solution's path but focuses on FI-CA specific settings).
5
Within the FI-CA configuration for document types, locate the document type in question. Ensure that it is correctly assigned to relevant posting areas and that associated posting rules and account determination settings are active and correctly configured for the company code and transaction type.
6
Pay attention to settings related to 'Document Category', 'Transaction Type', and 'Posting Rule' assignments. Ensure these align with the intended business process.
7
Save any necessary modifications and re-test the transaction.
3. Review and Adjust Master Data for Document Type Usage medium
Ensures that the business partner or contract account master data involved in the transaction is correctly linked to the supported document type.
1
Identify the business partner or contract account involved in the transaction that is failing.
2
Execute transaction code `BP` (for Business Partner) or `FK03` (for old account master data, though `BP` is preferred in S/4HANA) to display the master data.
3
Navigate to the relevant tabs or sections where document type assignments or restrictions might be configured. This could be under 'Identification', 'Roles', or specific FI-CA related sections within the Business Partner.
4
Check if there are any explicit restrictions or default settings for document types applied at the business partner or contract account level that might be excluding the currently used document type.
5
If such restrictions exist and are incorrect, modify the master data to allow or default to the correct document type. This might involve changing the 'Account Group' or specific settings within the FI-CA role.
6
Save the changes to the master data.
7
Attempt the transaction again.
