How To Fix RSRV175 - Characters not allowed in characteristic values (characteristic &1)

SAP Error Message - Details

• Message type: E = Error

• Message class: RSRV -

• Message number: 175

• Message text: Characters not allowed in characteristic values (characteristic &1)

Description
For characteristic &V1& the characteristic values are checked that
occur in the <AB>SID</> table. In doing so, the system checks the
following:
Only permitted characteris occur in the characteristic values
The characteristic values fit for the data type for the characteristic
(value 'ABC' cannot occur as a value for a numeric characteristic)
The values are available in internal format for characteristics with
specific conversion routines
The values have "meaningful" times for time characteristics
Initial values fit for the data type for the characteristic (a
characteristic that is only comprised of empty characters is only a
valid initial value for the type <AB>CHAR</>)
The values of the superior characteristics are made up of the above
checks for compounded characteristics
The function module <AB>RRSV_VALUE_CHECK_PLAUSIBILITY
</> is technically used for the check. This module is also used during
the data load into the transfer rules for checking characteristic
values.
Note that characteristic values might not be made up of several of the
above-mentioned checks. In such a case, the error message might not
make sense.

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?

If errors were found, the <AB>SID</> for the characteristic value is
also specified. Analyze whether this <AB>SID</> still occurs in the
(dimension tables of) InfoCubes.
If this is the case, the requests that include invalid characteristic
values have to be deleted and reloaded.
If the characteristic values are not used in the InfoCUbes, the
transaction data is correct. Invalid values could be used in
hierarchies or as attribute values for other characteristics. To
analyze this problem, refer to SAP.

• What is the cause and solution for SAP error message RSRV175 - Characters not allowed in characteristic values (characteristic &1) ?

  The SAP error message RSRV175 indicates that there are invalid characters in the characteristic values for a specific characteristic in your SAP BW (Business Warehouse) system. This error typically arises during data loading or when performing data validation checks.
  Cause:
  The error is triggered when the characteristic values contain characters that are not allowed. This can happen due to:
  
  Special characters (e.g., &, %, $, #, etc.) that are not permitted in the characteristic values.
  Leading or trailing spaces in the characteristic values.
  Incorrect data formats or types that do not conform to the expected standards for the characteristic.
  
  Solution:
  To resolve the RSRV175 error, you can follow these steps:
  
  
  Identify the Characteristic: The error message will specify which characteristic (denoted as &1) has the invalid values. Make a note of this characteristic.
  
  
  Check the Data Source: Review the data source from which the characteristic values are being loaded. Ensure that the data does not contain any invalid characters.
  
  
  Data Cleansing:
  
  Use data cleansing techniques to remove or replace invalid characters in the characteristic values.
  You can use tools like SAP Data Services or perform manual checks in the source system to clean the data.
  
  
  
  Use Transaction RSRV: 
  
  Go to transaction RSRV in SAP BW.
  Execute the "Check" function for the specific InfoObject (characteristic) to identify the records causing the issue.
  The system will provide a list of records with invalid values. You can then correct these values directly in the InfoObject maintenance or in the source system.
  
  
  
  Update the Data: After cleansing the data, reload it into the InfoProvider or the relevant data target.
  
  
  Validation: After making corrections, run the validation checks again to ensure that the error has been resolved.
  
  
  Related Information:
  
  
  Transaction Codes: 
  
  RSRV: For checking and validating data in BW.
  RSA1: For data modeling and InfoObject maintenance.
  
  
  
  Documentation: Refer to SAP Help documentation for specific characteristics and their allowed value formats.
  
  
  Data Quality Tools: Consider implementing data quality tools or processes to prevent such issues in the future.
  
  
  By following these steps, you should be able to resolve the RSRV175 error and ensure that your characteristic values conform to the required standards.
