How To Fix RSRV018 - Dimension key &1 missing in dimension table &2

SAP Error Message - Details

• Message type: E = Error

• Message class: RSRV -

• Message number: 018

• Message text: Dimension key &1 missing in dimension table &2

What causes this issue?

The dimension key &V1& that appears as field &V4& in the fact table,
does <ZH>not</> appear as a value of the DIMID field in the dimensions
table &V2&.
The facts belonging to dimension key &V1& are therefore no longer
connected to the master data of the characteristic in dimension.
The test checks whether all the associated facts are zero. If this is
the case, the inconsistency can be eliminated by deleteing these
fact records. If the errors cannot be eliminated, you have to rebuild
the InfoCube to attain a consistent state again.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

This inconsistency can occur if you use methods other than those found
in BW to delete data from the SAP BW tables (for example, maintaining
tables manually, using your own coding or database tools).

• What is the cause and solution for SAP error message RSRV018 - Dimension key &1 missing in dimension table &2 ?

  The SAP error message RSRV018 indicates that a dimension key is missing in a specified dimension table. This error typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when there is an inconsistency in the data model, particularly with InfoObjects and their associated dimension tables.
  Cause:
  
  
  Data Inconsistency: The dimension key that is referenced in the data model does not exist in the corresponding dimension table. This can happen due to:
  
  Data loading issues where the data was not loaded correctly.
  Deletion of dimension keys or InfoObjects that are still being referenced.
  Changes in the data model that were not properly reflected in the underlying tables.
  
  
  
  Transport Issues: If changes were transported from one system to another (e.g., from development to production), there might be inconsistencies if the transport did not include all necessary objects.
  
  
  Manual Changes: Manual changes to the database or dimension tables that bypass the standard SAP processes can lead to missing keys.
  
  
  Solution:
  
  
  Check Data Load: Verify that the data load process for the InfoProvider is functioning correctly. Check the data load logs for any errors or warnings that might indicate why the dimension key is missing.
  
  
  Repair the Dimension Table:
  
  Use transaction RSRV to run consistency checks on the InfoProvider. This transaction allows you to check for inconsistencies and repair them.
  If the dimension key is indeed missing, you may need to reload the data for the InfoProvider to ensure that all necessary keys are present.
  
  
  
  Recreate Missing Keys: If you identify that certain keys are missing, you may need to manually recreate them or adjust the data model to ensure that the keys are correctly populated.
  
  
  Check Transport Requests: If the issue arose after a transport, ensure that all relevant objects were included in the transport request. You may need to re-transport missing objects.
  
  
  Consult Documentation: Review SAP documentation or notes related to the specific version of SAP BW you are using, as there may be specific patches or updates that address this issue.
  
  
  Contact SAP Support: If the issue persists and you cannot resolve it, consider reaching out to SAP support for further assistance.

  RSA1: For accessing the Data Warehousing Workbench where you can manage InfoProviders and InfoObjects.
  
  
  
  SAP Notes: Search for relevant SAP Notes in the SAP Support Portal that may address specific issues related to dimension keys and data loading.
  
  
  Data Modeling: Understanding the data model and relationships between InfoObjects and InfoProviders is crucial for troubleshooting this error.
