Summary : 
      SAP NetWeaver BW environment update involves correcting issues with formula variable replacements from hierarchy attributes, and reinstating previous functionality for hierarchy node key replacements. Issues include non-working replacements and field symbol terminations. Solutions involve dynamic filtering for characteristics and adjusted functionalities resembling earlier versions pre-Support Package 22. Recommended actions include importing specific Support Packages (e.g., SAPKW70025 for NetWeaver BW 7.00) following the detailed guidance in related SAPBINews Notes. For immediate fixes, implement correction instructions directly, ensuring familiarity with transaction SNOTE as per Note 875986.
