  The SAP error message /SAPAPO/SDP254 Drill up sequence not allowed typically occurs in the context of SAP Advanced Planning and Optimization (APO), particularly when working with the Supply Network Planning (SNP) or Demand Planning (DP) modules. This error is related to the drill-up functionality in the planning books or data views, which allows users to navigate through different levels of data aggregation.
  Cause:
  The error message indicates that the system does not allow a drill-up operation due to the current context or state of the data. Common causes include:
  
  Data Aggregation Level: The data you are trying to drill up from may not have a valid aggregation level defined, or the aggregation level does not support the drill-up operation.
  Planning Book Configuration: The planning book or data view may not be configured correctly to allow drill-up operations.
  Hierarchy Issues: If you are working with a hierarchy (e.g., product hierarchy, location hierarchy), there may be inconsistencies or issues with the hierarchy structure that prevent the drill-up.
  Data Locking: If the data is locked for editing or if there are ongoing processes that prevent changes, this could also lead to this error.

  Data Locking: Check if there are any locks on the data that might be preventing the drill-up. You can use transaction codes like /SAPAPO/SDP94 to check for locks.
  User Authorizations: Ensure that the user has the necessary authorizations to perform drill-up operations in the planning book.
