SAP Error Message - Details

• Message type: E = Error

• Message class: WUSL - Messages for where-used list

• Message number: 130

• Message text: Too many lines may result in a memory overflow.

What causes this issue?

You have entered a maximum number of hits, which could exceed the
maximum amount of memory for the table selected. This may also occur if
you do not make an entry in the maximum number of hits, as all lines
should then be read.

System Response

The system calculates the probable use of memory, and adjusts the number
of lines to the largest possible value. In the standard system, a memory
requirement in the order of 1.5 GB is allowed. If you would like to
change this value, make an entry in table T811FLAGS with the following
values:
TAB = 'SE16H'
FIELD = 'SELSIZE_MAX'
VALMIN = the value in bytes corresponding to the amount of memory
(minimum 10,000)
If you make the value too high, the memory available may be exceeded.

How to fix this error?

You do not need to do anything further. The correct value is
automatically transferred.

Procedure for System Administrators

• What is the cause and solution for SAP error message WUSL130 - Too many lines may result in a memory overflow. ?

  The SAP error message WUSL130 ("Too many lines may result in a memory overflow") typically occurs when a user attempts to process or display a large number of line items in a report or transaction, which can lead to performance issues or memory overflow errors.
  Cause:
  
  Excessive Data Volume: The primary cause of this error is that the system is trying to handle too many line items at once, which exceeds the memory limits set for the transaction or report.
  Inefficient Queries: Poorly optimized queries or reports that pull in too much data without proper filtering can lead to this issue.
  System Configuration: The SAP system may not be configured to handle large datasets efficiently, leading to memory constraints.
  
  Solution:
  
  
  Limit Data Selection: 
  
  Use selection criteria to limit the number of records being processed. For example, filter by date ranges, specific document types, or other relevant parameters.
  If applicable, consider breaking down the report into smaller segments.
  
  
  
  Optimize Queries:
  
  Review and optimize the underlying queries or reports to ensure they are efficient and only retrieve necessary data.
  Use indexes and other database optimization techniques to improve performance.

  If the report can be run in the background, consider scheduling it to run in the background instead of in the foreground. This can help manage memory usage more effectively.
  
  
  
  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.
