• What is the cause and solution for SAP error message RSM2853 - Reading data from PSA & started ?

  The SAP error message RSM2853 typically indicates an issue related to the extraction of data from the Persistent Staging Area (PSA) during the data loading process in SAP BW (Business Warehouse). This message is often associated with the data transfer process (DTP) and can occur for various reasons.
  Cause:
  
  Data Load Issues: The error may arise if there are issues with the data being loaded from the PSA, such as data inconsistencies or format mismatches.
  PSA Table Locking: If the PSA table is locked by another process, it can prevent the current process from reading the data.
  Data Transfer Process (DTP) Configuration: Incorrect settings in the DTP can lead to issues when reading data from the PSA.
  Data Quality Issues: If the data in the PSA is corrupted or does not meet the expected criteria, it can cause errors during the read operation.
  System Performance: High system load or performance issues can also lead to timeouts or failures in reading data.
  
  Solution:
  
  Check DTP Settings: Review the configuration of the DTP to ensure that it is set up correctly. Pay attention to filters, transformations, and any other settings that might affect data extraction.
  Monitor PSA Table: Check the PSA table for locks or ongoing processes. You can use transaction codes like SM12 to see if there are any locks on the PSA table.
  Data Quality Check: Validate the data in the PSA for any inconsistencies or errors. You may need to clean or correct the data before attempting to load it again.
  Reprocess the Data: If the data in the PSA is valid, try reprocessing the data load. You can do this by executing the DTP again.
  System Performance: Monitor system performance and resource usage. If the system is under heavy load, consider scheduling data loads during off-peak hours.
  Check Logs: Review the logs for more detailed error messages that can provide insights into the specific issue. You can check the DTP execution logs for any additional error messages.
