• What is the cause and solution for SAP error message PSSC_NET320 - Execution with partition size &1 (&2) ?

  The SAP error message PSSC_NET320, which states "Execution with partition size &1 (&2)," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when there are issues related to data partitioning during data processing or extraction.
  Cause:
  
  Partition Size Limitations: The error often indicates that the partition size specified for a data load or processing operation exceeds the allowed limits. This can happen if the data being processed is too large for the defined partition size.
  Configuration Issues: Incorrect configuration settings for data partitioning in the InfoProvider or data source can lead to this error.
  Resource Constraints: Insufficient system resources (like memory or CPU) can also trigger this error, especially when handling large datasets.
  
  Solution:
  
  Adjust Partition Size: Review and adjust the partition size settings in your data model or InfoProvider. You may need to increase the partition size to accommodate larger datasets.
  Optimize Data Load: If possible, optimize the data load process by breaking down large datasets into smaller chunks or batches that fit within the partition size limits.
  Check Configuration: Ensure that the configuration settings for the InfoProvider or data source are correctly set up for partitioning. This includes checking the settings in the Data Warehousing Workbench or the relevant transaction codes.
  Monitor System Resources: Check the system resources (memory, CPU) during the execution of the data load. If resources are constrained, consider optimizing the system or scheduling the data load during off-peak hours.
  Consult SAP Notes: Look for any relevant SAP Notes or documentation that may provide additional insights or patches related to this error.
  
  Related Information:
  
  SAP BW Documentation: Review the official SAP BW documentation for best practices on data partitioning and performance optimization.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have implemented.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1 (Data Warehousing Workbench) and RSCUSTV10 (for customizing settings) to manage and troubleshoot data loading processes.
