How To Fix RSDS059 - Character-like PSA with access method &1 not permitted

SAP Error Message - Details

• Message type: E = Error

• Message class: RSDS - New DataSource

• Message number: 059

• Message text: Character-like PSA with access method &1 not permitted

What causes this issue?

You have set the indicator so that the PSA stores the data in the
character structure. However the extractor &V1& extracts directly into
the application structure. Thus it is neither possible nor necessary to
store the data in the character structure.

System Response

The function is terminated

How to fix this error?

Remove the indicator or choose another extractor.

• What is the cause and solution for SAP error message RSDS059 - Character-like PSA with access method &1 not permitted ?

  The SAP error message RSDS059 indicates that there is an issue with accessing a Persistent Staging Area (PSA) that is defined as character-like, but the access method being used is not permitted for that type of PSA. This typically occurs in the context of data extraction and loading processes in SAP BW (Business Warehouse).
  Cause:
  The error is caused by attempting to use an access method that is incompatible with the data type of the PSA. Specifically, the PSA is defined to hold character-like data, but the access method specified (denoted by &1 in the error message) is not suitable for this type of data. This can happen if:
  
  The PSA is incorrectly configured.
  The data source is not compatible with the defined PSA structure.
  There is a mismatch between the data types expected by the data source and the PSA.
  
  Solution:
  To resolve the RSDS059 error, you can take the following steps:
  
  
  Check PSA Configuration:
  
  Go to the Data Warehousing Workbench (transaction RSA1).
  Navigate to the PSA in question and check its structure and data types.
  Ensure that the PSA is correctly defined to match the data types of the incoming data.
  
  
  
  Review Data Source:
  
  Verify the data source configuration to ensure it is compatible with the PSA.
  Check if the data source is set up to extract character-like data and that it matches the PSA's structure.
  
  
  
  Adjust Access Method:
  
  If the access method being used is not appropriate for character-like data, consider changing it to a suitable method.
  You may need to adjust the extraction process or the transformation rules to ensure compatibility.
  
  
  
  Test Data Load:
  
  After making the necessary adjustments, perform a test data load to see if the error persists.
  Monitor the logs for any additional errors or warnings that may provide further insight.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific data source and PSA configuration for additional guidance.
  
  
  
  Related Information:
  
  PSA (Persistent Staging Area): A storage area in SAP BW where data is temporarily held before being transformed and loaded into the data warehouse.
  Access Methods: Different methods used to read data from the PSA, such as direct access or using a specific data extraction technique.
  Data Types: Understanding the data types (character-like, numeric, etc.) is crucial for ensuring compatibility between data sources and PSAs.
  
  If the issue persists after following these steps, consider reaching out to SAP support or consulting with a BW expert for further assistance.
