  SAP Error Message:
  WRF_AT_GENERATE106
  
  Text: Restrict the selection of the purchasing list data further
  
  Cause:
  This error occurs when the selection criteria for generating or processing purchasing list data (such as purchase requisitions, purchase orders, or related reports) are too broad or return too many records. The system detects that the volume of data to be processed is excessively large, which could lead to performance issues or timeouts.
  In other words, the selection parameters you have entered are not restrictive enough, causing the system to attempt to handle an unmanageably large dataset.
  
  Solution:
  
  
  Narrow down the selection criteria:
  
  Refine your selection parameters to reduce the number of records. For example:
  
  Limit the date range (e.g., shorter periods)
  Specify particular purchasing groups, vendors, or plants
  Use more specific material numbers or purchasing document numbers
  Filter by status or other relevant fields
  
  
  
  Use additional filters:
  
  Apply more filters in the selection screen to reduce the dataset size.
  
  
  Run the report/process in smaller batches:
  
  If you need to process a large volume of data, consider splitting the selection into smaller chunks and running the process multiple times.
  
  
  Check for unnecessary broad selections:
  
  Avoid selecting "All" or leaving fields blank if they are optional but can help restrict the data.
  
  
  
  Related Information:
  
  This message is typically encountered in purchasing-related reports or transactions that generate lists or process purchasing documents.
  It is a safeguard to prevent system overload and ensure better performance.
  If you consistently need to process large volumes of data, consider discussing with your SAP Basis or functional team about performance tuning or background job scheduling.
  Sometimes, SAP Notes or patches may address performance issues related to large data processing in purchasing modules.
