• What is the cause and solution for SAP error message GU951 - Check the storage capacity of the specified export file ?

  The SAP error message GU951, which states "Check the storage capacity of the specified export file," typically occurs during the export of data from SAP systems, particularly when the system is trying to create an export file that exceeds the available storage capacity. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Insufficient Disk Space: The most common cause of this error is that the disk space on the server where the export file is being created is insufficient.
  File Size Limitations: Some file systems have limitations on the maximum file size that can be created. If the export file exceeds this limit, the error may occur.
  Configuration Issues: There may be configuration settings in the SAP system that limit the size of export files or the amount of data that can be exported at one time.
  
  Solutions:
  
  
  Check Disk Space:
  
  Verify the available disk space on the server where the export file is being created. You can use system commands (like df -h on Unix/Linux) to check disk usage.
  If space is low, consider deleting unnecessary files or moving files to another storage location to free up space.
  
  
  
  Change Export Parameters:
  
  If the data being exported is too large, consider breaking it down into smaller chunks. This can be done by adjusting the selection criteria or exporting in smaller batches.
  
  
  
  File System Limitations:
  
  Check the file system type and its limitations. For example, FAT32 has a maximum file size limit of 4GB. If you are using such a file system, consider switching to a file system that supports larger files (like NTFS for Windows or ext4 for Linux).
  
  
  
  SAP Configuration:
  
  Review the SAP configuration settings related to data export. Ensure that there are no restrictions set on the maximum size of export files.
  
  
  
  Temporary Files:
  
  Ensure that there is enough space for temporary files that may be created during the export process. Sometimes, the export process requires additional space for temporary storage.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
