  The SAP error message /SAPAPO/RSP540 Block on forming day package (release step) has been reset typically occurs in the context of SAP Advanced Planning and Optimization (APO) when there is an issue with the planning process, particularly during the release of a day package in the Supply Network Planning (SNP) or Production Planning and Detailed Scheduling (PP/DS) modules.
  Cause:
  
  Data Inconsistencies: There may be inconsistencies in the master data or transaction data that prevent the system from forming the day package.
  Locking Issues: Another process might be holding a lock on the resources or data that are needed to complete the day package formation.
  Configuration Issues: Incorrect configuration settings in the planning area or planning book can lead to this error.
  Resource Availability: If the resources required for the planning process are not available or are incorrectly defined, it can cause this error.
  Planning Version Issues: The planning version being used may not be correctly set up or may have been changed unexpectedly.
