• What is the cause and solution for SAP error message KM891 - Maximum number of document lines reached ?

  The SAP error message KM891, which states "Maximum number of document lines reached," typically occurs when you are trying to create or modify a document (such as a purchase order, invoice, or other financial document) that exceeds the maximum number of line items allowed by the system configuration.
  Cause:
  
  Line Item Limit: Each document type in SAP has a predefined limit on the number of line items it can contain. This limit is set in the system configuration and can vary based on the document type.
  Configuration Settings: The maximum number of line items is determined by the system settings, which may have been set to a low value for performance reasons or due to specific business requirements.
  
  Solution:
  
  Check Document Type Limits: Verify the maximum number of line items allowed for the specific document type you are working with. This can usually be found in the configuration settings of the relevant module (e.g., MM, SD, FI).
  Reduce Line Items: If you are hitting the limit, consider splitting the document into multiple documents to stay within the allowed number of line items.
  Configuration Change: If your business process requires more line items than currently allowed, you may need to adjust the configuration settings. This typically requires access to the SAP Customizing Implementation Guide (IMG) and may involve:
  
  Navigating to the relevant configuration area (e.g., Materials Management for purchase orders).
  Finding the setting for maximum line items and increasing the limit.
  Consulting with your SAP Basis or configuration team to ensure that any changes are appropriate and do not negatively impact system performance.
  
  
  Consult Documentation: Review SAP documentation or notes related to the specific module you are working with for any additional guidance or best practices.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or updates related to this error message. SAP frequently releases notes that may provide additional context or solutions.
  User Roles and Permissions: Ensure that you have the necessary permissions to make changes to document configurations if you are attempting to adjust system settings.
  Testing Changes: After making any configuration changes, it is advisable to test the changes in a development or quality assurance environment before applying them to the production system.
