• What is the cause and solution for SAP error message CNVMBTCHECK004 - &1| More than one top level structure in sender hierarchy ?

  The SAP error message CNVMBTCHECK004 indicates that there is more than one top-level structure in the sender hierarchy during a data migration or conversion process. This typically occurs in the context of using the SAP Migration Cockpit or other data migration tools where the system expects a single top-level structure for the data being processed.
  Cause:
  The error arises when the data being imported or processed has multiple entries that are considered top-level structures. In a hierarchical data model, a top-level structure is the primary entry point, and having more than one can lead to ambiguity in how the data should be processed.

  Merging records.
  Adjusting the hierarchy to ensure only one top-level entry exists.
  
  
  
  Check Mapping Configuration: Review the mapping configuration in the migration tool. Ensure that the mapping is set up correctly to reflect the intended hierarchy.
  
  
  Use Data Transformation Tools: If necessary, use data transformation tools or scripts to preprocess the data before importing it into SAP. This can help in restructuring the data to meet the requirements.
  
  
  Consult Documentation: Refer to the SAP documentation related to the specific migration tool you are using. There may be specific guidelines or best practices for structuring your data.
