SAP S/4HANA Error 4677: Data Flow Missing
Description
This error indicates that a data flow, which is crucial for data provisioning or processing, cannot be found within your SAP S/4HANA system. It typically occurs when an application or process attempts to access a data flow definition that either doesn't exist, is incorrectly named, or is inaccessible.
Error Message
ERR_DATAPROV_DATAFLOW_DOES_NOT_EXIST
Known Causes
3 known causesData Flow Deleted or Renamed
The required data flow object was inadvertently deleted, or its technical name was changed, making it inaccessible to dependent processes.
Incorrect Configuration Reference
A configuration setting, such as a data transfer process or a reporting query, refers to a data flow that either never existed or has a typo in its name.
Incomplete Transport or Deployment
The data flow object was not successfully deployed or transported to the target SAP S/4HANA environment, leading to its absence.
Solutions
3 solutions available1. Verify Data Source and Target Mapping in CDS Views medium
Ensures that the underlying CDS views for the data flow are correctly defined and mapped.
1
Identify the specific Data Provider (DP) or Analytical Query that is triggering error 4677. This often involves tracing the execution path or examining the error context within the SAP Fiori or SAP GUI application.
2
Access the SAP S/4HANA system using SAP GUI and navigate to transaction `SE11` (ABAP Dictionary) or `SE80` (Object Navigator).
3
Locate the Composite Provider (or the relevant data source if it's a direct query) that is being used by the DP or Analytical Query. In S/4HANA, this is often a CDS view exposed as an OData service or used within analytical tools.
4
Examine the definition of the Composite Provider (or the primary CDS view). Pay close attention to the source objects (e.g., other CDS views, tables) and how their fields are mapped to the output fields of the Composite Provider. Ensure all expected source fields are present and correctly linked.
Example: If your Composite Provider is a CDS view like `ZCL_COMPOSITE_VIEW`, check its definition for `FROM` clauses and join conditions. Ensure all referenced CDS views or tables exist and are accessible.5
If the Composite Provider relies on other CDS views, navigate to and verify the definition of those dependent CDS views as well. Ensure their data sources and field definitions are intact.
6
If any inconsistencies are found (e.g., missing source fields, incorrect data types, non-existent referenced objects), correct the CDS view definitions. This might involve adjusting associations, joins, or field selections.
Example: To modify a CDS view, you would typically go to `SE11`, enter the CDS view name, click 'Change', and edit the SQL DDL source.7
Activate all modified CDS views and their dependent objects. After activation, re-test the affected SAP Fiori app or analytical report.
2. Reactivate Affected ABAP Dictionary Objects easy
A quick solution to resolve inconsistencies by reactivating relevant DDIC objects.
1
Identify the primary CDS view or Calculation View that serves as the data source for the failing analytical query or OData service. This is often evident from the error message or application configuration.
2
Access SAP GUI and navigate to transaction `SE11` (ABAP Dictionary).
3
Enter the name of the identified CDS view or Calculation View in the 'Data type' field and click 'Change'.
4
Press `Ctrl+F3` or navigate to 'Dictionary' -> 'Activate' to reactivate the object. This process will also check and attempt to reactivate any dependent objects.
5
If the object is a Calculation View (often used in BW/4HANA or SDA scenarios), you might need to use transaction `RSCALI` or `RS_BW_ANALYTICS_TOOL` and select the relevant view for reactivation. For CDS views, `SE11` is the primary tool.
6
After successful reactivation, clear the relevant application caches if applicable (e.g., OData service cache using transaction `/IWFND/CACHE_CLEANUP`).
7
Re-test the application or report that was encountering the error.
3. Check and Correct Data Source Metadata in BW/4HANA or SDA Context advanced
Addresses issues where data flow metadata is missing or corrupted in a BW/4HANA or SDA setup.
1
Determine if the data flow error is occurring within a BW/4HANA modeling environment or if it involves a Smart Data Access (SDA) connection to an external data source.
2
If using BW/4HANA modeling (e.g., BW Modeling Tools in Eclipse), open the relevant CompositeProvider or CalculationView in the BW Modeling perspective.
3
Thoroughly review the 'Data Sources' or 'Sources' tab/section of your modeling object. Ensure that all referenced InfoProviders (e.g., ADSOs, Queries) or external data sources are correctly selected and configured.
Example: In BW Modeling Tools, this would involve checking the graphical editor for the CompositeProvider and inspecting the connection lines and source objects.4
Verify that the underlying data sources (e.g., ADSOs, TransientProviders) exist, are active, and contain the expected fields. If the data source is an ADSO, check its structure and content.
5
If using SDA, navigate to transaction `SDA_REG` (or similar) to check the status and configuration of your remote data sources and virtual data models (VDMs). Ensure the connection to the source system is active and the metadata is synchronized.
6
If the data source is a CDS view exposed via SDA, ensure the CDS view is active in the source system and that the corresponding VDMs in BW/4HANA are correctly defined and pointing to the active CDS view.
7
If any discrepancies are found, correct the modeling artifacts (CompositeProvider, CalculationView, ADSO, VDM) and redeploy or reactivate them. For SDA, this might involve re-registering the remote source or refreshing the VDMs.
8
After making corrections, clear relevant caches (e.g., BW/4HANA caches, OData service caches) and re-test the affected reports or applications.
