• What is the cause and solution for SAP error message /SCWM/LC1157 - Selection too large, choose less input data ?

  The SAP error message /SCWM/LC1157 Selection too large, choose less input data typically occurs in the context of the SAP Extended Warehouse Management (EWM) module. This error indicates that the selection criteria you have provided for a particular operation (such as a report, transaction, or data retrieval) are too broad, resulting in an excessively large dataset that the system cannot process efficiently.
  Cause:
  
  Excessive Data Selection: The selection criteria you have entered may be too broad, leading to a large number of records being selected. This can happen if you are not filtering the data sufficiently (e.g., selecting all items without specific criteria).
  System Limitations: SAP has built-in limits to prevent performance issues. If the selection exceeds these limits, the system will throw this error.
  Complex Queries: If you are using complex queries or multiple selection criteria that result in a large dataset, it may trigger this error.
  
  Solution:
  
  Narrow Down Selection Criteria: Review the selection criteria you are using and try to narrow them down. For example, instead of selecting all items, specify a range of items, dates, or other relevant filters.
  Use Additional Filters: If applicable, add more filters to your selection to reduce the number of records being processed. This could include filtering by warehouse, product type, status, etc.
  Batch Processing: If you need to process a large amount of data, consider breaking it down into smaller batches. This can help avoid overwhelming the system.
  Check for Default Values: Sometimes, default values in selection screens can lead to broader selections than intended. Ensure that you are aware of any default settings that may be affecting your selection.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on selection limits for the transaction or report you are using.
  
  Related Information:
  
  Transaction Codes: This error can occur in various transactions within the EWM module, such as inventory management, stock transfers, or reporting transactions.
  Performance Considerations: Always consider the performance implications of your selections in SAP. Large datasets can lead to slow performance or timeouts.
  SAP Notes: Check for any relevant SAP Notes or updates that may address this issue or provide additional guidance on handling large selections.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with your SAP support team or a technical consultant who can analyze the specific context of the error and provide tailored assistance.
