• What is the cause and solution for SAP error message RSANA_UMM_API063 - Supplied signature and existing signature are not consistent ?

  The SAP error message RSANA_UMM_API063 indicates that there is a mismatch between the supplied signature and the existing signature in the system. This error typically occurs in the context of data extraction or data transfer processes, particularly when using the SAP BW (Business Warehouse) or SAP HANA systems.
  Cause:
  
  Signature Mismatch: The most common cause of this error is that the data being processed has a different structure or format than what is expected. This can happen if there have been changes to the data model, such as changes in the fields, data types, or the overall structure of the data being extracted or transferred.
  Data Source Changes: If the underlying data source has been modified (e.g., fields added, removed, or changed), the signature that the system expects may no longer match the actual data being processed.
  Inconsistent Data: If there are inconsistencies in the data being loaded or extracted, such as missing fields or incorrect data types, this can lead to signature mismatches.
  
  Solution:
  
  Check Data Model Changes: Review any recent changes made to the data model or data source. Ensure that the data structure matches what the system expects.
  Recreate the Data Source: If the data source has changed significantly, consider recreating the data source in SAP BW or HANA to ensure that the signature is updated accordingly.
  Validate Data: Check the data being processed for any inconsistencies. Ensure that all required fields are present and that the data types match the expected types.
  Update InfoObjects: If you are using InfoObjects in SAP BW, ensure that they are updated and consistent with the data being loaded.
  Check for Transport Issues: If the issue arose after a transport, ensure that all relevant objects were transported correctly and that there are no missing components.
  Debugging: If the issue persists, consider debugging the process to identify where the mismatch is occurring. This may involve looking at the data flow and transformation logic.
