Smart SAP Assistant

• What is the cause and solution for SAP error message RSDS081 - The maximum number of segments is limited to 99 ?

  The SAP error message RSDS081 indicates that you have exceeded the maximum number of segments allowed in a DataSource. In SAP BW (Business Warehouse), a DataSource can have a maximum of 99 segments. Each segment corresponds to a different field or attribute in the data structure.
  Cause:
  The error occurs when you attempt to create or modify a DataSource that has more than 99 segments. This can happen if:
  
  You are trying to include too many fields in a single DataSource.
  You are working with a complex data structure that requires more segments than allowed.
  
  Solution:
  To resolve the RSDS081 error, you can consider the following approaches:
  
  
  Reduce the Number of Segments:
  
  Review the fields included in the DataSource and remove any unnecessary fields or attributes.
  Combine related fields into a single segment if possible.
  
  
  
  Create Multiple DataSources:
  
  If you need to work with more than 99 segments, consider splitting the DataSource into multiple DataSources. Each DataSource can then handle a subset of the data.
  
  
  
  Use InfoObjects:
  
  Instead of adding many fields directly to the DataSource, consider using InfoObjects. InfoObjects can help you manage data more efficiently and may reduce the number of segments needed.
  
  
  
  Check for Redundant Fields:
  
  Ensure that there are no redundant fields in your DataSource. Sometimes, fields may be included that are not necessary for your reporting or analysis.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP BW administrator for best practices on structuring DataSources.
