• What is the cause and solution for SAP error message GL400 - Only one rollup sequence is supported in hierarchical summarization ?

  The SAP error message GL400: Only one rollup sequence is supported in hierarchical summarization typically occurs in the context of financial reporting or when working with hierarchical data structures in SAP. This error indicates that the system has encountered multiple rollup sequences in a hierarchical summarization process, which is not supported.
  Cause:
  
  Multiple Rollup Sequences: The primary cause of this error is that the system has detected more than one rollup sequence defined for the same hierarchical structure. In SAP, hierarchical summarization is designed to work with a single rollup sequence to ensure consistency in data aggregation.
  Configuration Issues: There may be a misconfiguration in the settings related to the hierarchical summarization or rollup sequences in the financial reporting module.
  Data Model Issues: The data model may have been altered or incorrectly set up, leading to conflicting rollup sequences.
  
  Solution:
  
  Review Rollup Sequences: Check the configuration of rollup sequences in the relevant financial reporting settings. Ensure that only one rollup sequence is defined for the hierarchical structure you are working with.
  Adjust Hierarchical Structure: If multiple rollup sequences are necessary for different reporting needs, consider restructuring the hierarchy or creating separate reports for each rollup sequence.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on configuring hierarchical summarization and rollup sequences correctly.
  Testing: After making changes, test the reporting or summarization process again to ensure that the error is resolved.
  Seek Support: If the issue persists, consider reaching out to SAP support or your internal SAP team for further assistance.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on hierarchical summarization.
  Transaction Codes: Familiarize yourself with transaction codes related to financial reporting and hierarchical structures, such as OB58 (for defining rollup sequences) or S_ALR_87012301 (for financial reports).
  Training and Documentation: Ensure that users involved in financial reporting are trained on the proper configuration and use of hierarchical summarization in SAP.
  
  By addressing the configuration and ensuring that only one rollup sequence is used, you should be able to resolve the GL400 error and proceed with your reporting tasks.
