SAP Error Message - Details

• Message type: E = Error

• Message class: CAWUSL - Message Class for Generic Table Browser

• Message number: 130

• Message text: Too many lines can lead to memory overflow

What causes this issue?

The maximum number of lines you have chosen for the given table could
reach the memory limit and lead to a GUI-Crash or memory dump. This will
also happen if you left the maximum number of lines 'space'.

System Response

The system calculates the probable memory used and adapts the maximum
number of lines beyond this value. The allowed system standard memory
usage is approximately 1.5GB of data. You can change this value by
entering an entry into table GTB_FLAGS with the key
TAB = 'S416H'
FIELD = 'SELSIZE_MAX'
VALMIN = the value in Byte you want to allow (minimum 10.000)
If you set the value too high, a memory dump can occur.

How to fix this error?

No action required, the calculated value is automatically taken over.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message CAWUSL130 - Too many lines can lead to memory overflow ?

  The SAP error message CAWUSL130: Too many lines can lead to memory overflow typically occurs when a user attempts to process a large amount of data in a single transaction or report, which exceeds the system's memory limits. This can happen in various contexts, such as when generating reports, processing large datasets, or executing certain transactions that involve extensive data manipulation.
  Causes:
  
  Excessive Data Volume: The primary cause is attempting to handle too many line items or records in a single operation, which can overwhelm the system's memory.
  Inefficient Queries: Poorly optimized queries or reports that pull in more data than necessary can lead to this error.
  System Configuration: The SAP system may not be configured to handle large datasets efficiently, leading to memory issues.
  Hardware Limitations: Insufficient server resources (CPU, RAM) can exacerbate the problem, especially in environments with high data volume.
  
  Solutions:
  
  Limit Data Selection: Modify the selection criteria to reduce the number of records being processed. For example, use date ranges, specific criteria, or filters to limit the dataset.
  Batch Processing: If possible, break down the operation into smaller batches. Instead of processing all records at once, process them in smaller groups.
  Optimize Queries: Review and optimize any custom queries or reports to ensure they are efficient and only retrieve necessary data.
  Increase Memory Allocation: If you have access to system configuration, consider increasing the memory allocation for the SAP application server. This may involve working with your IT or SAP Basis team.
  Use Alternative Transactions: If the error occurs in a specific transaction, check if there are alternative transactions or reports that can handle the data more efficiently.
  Check for Updates: Ensure that your SAP system is up to date with the latest patches and updates, as performance improvements and bug fixes may address memory issues.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any specific recommendations or fixes related to this error. SAP frequently releases notes that address known issues and provide guidance.
  System Monitoring: Use SAP's monitoring tools (like ST02 for memory management) to analyze memory usage and identify bottlenecks.
  Performance Tuning: Engage in performance tuning of the SAP system, which may involve database optimization, adjusting server parameters, or reviewing application performance.
  
  If the problem persists after trying these solutions, it may be beneficial to consult with your SAP Basis team or reach out to SAP support for further assistance.
