• What is the cause and solution for SAP error message RSO_RES_ADSO188 - NLS not possible; aDSO '&1' contains fields with names greater than &2 ?

  The SAP error message RSO_RES_ADSO188 indicates that there is an issue with the naming of fields in an Advanced DataStore Object (aDSO). Specifically, the error states that the aDSO contains fields with names that exceed a certain length limit, which is defined by the system.
  Cause:
  The error occurs when one or more field names in the aDSO exceed the maximum allowed length. In SAP BW/4HANA, the maximum length for field names is typically 30 characters. If any field name exceeds this limit, the system cannot process the aDSO correctly, leading to the error message.
  Solution:
  To resolve this error, you need to ensure that all field names in the aDSO are within the allowed length. Here are the steps you can take:
  
  
  Identify the Fields: Check the field names in the aDSO that are causing the issue. You can do this by reviewing the aDSO structure in the SAP BW modeling tools.
  
  
  Rename Fields: If you find any field names that exceed the maximum length, rename them to shorter names that comply with the length restriction. Ensure that the new names are meaningful and maintain clarity.
  
  
  Adjust Data Sources: If the aDSO is populated from data sources (like InfoSources or DataSources), ensure that the field names in those sources also comply with the length restrictions.
  
  
  Re-activate the aDSO: After making the necessary changes, you may need to re-activate the aDSO to apply the changes.
  
  
  Test the Changes: Once the changes are made, test the data loading process to ensure that the error no longer occurs.
