• What is the cause and solution for SAP error message CMS052 - Internal error, buffer is too small ?

  The SAP error message CMS052, which states "Internal error, buffer is too small," typically indicates that a buffer used by the system to store data is not large enough to accommodate the data being processed. This can occur in various contexts within SAP, such as during data transfers, report generation, or when accessing certain transactions.
  Causes:
  
  Data Volume: The amount of data being processed exceeds the predefined buffer size.
