  The SAP error message 00855, which states "Maximum allowed amount of heap memory (abap/heap_area_total) exceeded," indicates that the ABAP program has exceeded the maximum limit of heap memory allocated for the ABAP runtime environment. This can occur due to various reasons, such as inefficient coding, memory leaks, or processing large datasets.
  Causes:
  
  Inefficient Code: Poorly optimized ABAP code that consumes excessive memory.
  Large Data Processing: Processing large internal tables or datasets without proper handling can lead to high memory consumption.
  Memory Leaks: Objects that are not properly released or cleaned up can lead to memory leaks, causing the heap memory to fill up.
  Configuration Limits: The system configuration may have a low limit set for the heap memory.
  
  Solutions:
  
  
  Optimize ABAP Code:
  
  Review and optimize the code to ensure efficient memory usage. Avoid unnecessary data retrieval and processing.
  Use appropriate data types and structures. For example, use HASHED TABLE or SORTED TABLE where applicable.
