How To Fix RSRV042 - From zero, there are various facts to dimension key &1 in &2

SAP Error Message - Details

• Message type: E = Error

• Message class: RSRV -

• Message number: 042

• Message text: From zero, there are various facts to dimension key &1 in &2

What causes this issue?

In the dimension key &V1& that does not appear in the dimsensions
table, there are fact records that are not equal to zero. The system is
no longer able to determine which combination of characteristic values
these fact records belong to, and the only way to remove these
inconsistencies is to delete the contents of the InfoCubes and reload
them.
The fact records mentioned above are not currently included in any
report. This means that the figures that you get in reports could be
incorrect if they refer to these fact records. For this reason, it is
not enough to delete the fact records. If you do delete them, the data
will be consistent again, but you will not be reporting on the figures
that you loaded.

System Response

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

• What is the cause and solution for SAP error message RSRV042 - From zero, there are various facts to dimension key &1 in &2 ?

  The SAP error message RSRV042 indicates that there is an issue with the data in a specific InfoObject (dimension) in your SAP BW (Business Warehouse) system. The message typically means that there are no records in the fact table that correspond to the specified dimension key, which can lead to inconsistencies in your data model.
  Cause:
  
  Missing Data: The dimension key specified in the error message does not have any corresponding entries in the fact table. This can happen if the data load process did not populate the fact table correctly.
  Data Model Issues: There may be issues with the data model, such as incorrect relationships between the fact and dimension tables.
  Data Extraction Problems: Problems during the data extraction process from the source system can lead to missing records in the fact table.
  Data Deletion: Records may have been deleted from the fact table, leading to a mismatch with the dimension.
  
  Solution:
  
  Check Data Load: Verify that the data load process for the InfoProvider (e.g., InfoCube, DSO) has been executed successfully. Check for any errors or warnings in the data load process.
  Data Consistency Check: Use transaction code RSRV to run consistency checks on the InfoProvider. This can help identify any inconsistencies between the fact and dimension tables.
  Review Data Model: Ensure that the relationships between the fact and dimension tables are correctly defined. Check the InfoObject settings and ensure that they are properly configured.
  Reprocess Data: If necessary, reprocess the data load to ensure that all records are correctly populated in the fact table.
  Analyze Data: Use queries or reports to analyze the data in both the fact and dimension tables to identify any discrepancies.
  Check for Deletions: Investigate if any data deletion processes have been executed that might have removed records from the fact table.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like RSRV (for consistency checks), RSA1 (for data modeling), and RSTT (for monitoring data loads).
  SAP Notes: Check SAP Notes related to RSRV042 for any specific patches or updates that may address known issues.
  Documentation: Refer to SAP BW documentation for best practices on data modeling and data loading processes.
  
  By following these steps, you should be able to identify the root cause of the RSRV042 error and implement the necessary solutions to resolve it.
