• What is the cause and solution for SAP error message M8201 - Deselect specified lines before making adjustment postings ?

  The SAP error message M8201, which states "Deselect specified lines before making adjustment postings," typically occurs in the context of inventory management or material document processing. This error indicates that there are certain lines selected in a transaction that cannot be processed together due to specific conditions or rules set in the system.
  Cause:
  
  Selection of Multiple Lines: The error often arises when a user attempts to post adjustments for multiple line items that are not compatible with each other. For example, if some lines are related to different materials, plants, or storage locations, the system may not allow adjustments to be made simultaneously.
  Document Status: The selected lines may have different statuses (e.g., some may be already posted, while others are not), which can lead to conflicts during the adjustment process.
  Inconsistent Data: There may be inconsistencies in the data associated with the selected lines, such as different valuation types or stock types.
  
  Solution:
  
  Deselect Lines: The immediate solution is to deselect the lines that are causing the conflict. Review the selected items and ensure that only compatible lines are selected for the adjustment posting.
  Check Document Status: Verify the status of each line item. Ensure that all selected lines are eligible for adjustment and that none are already processed or locked.
  Review Data Consistency: Check for any inconsistencies in the data for the selected lines. Ensure that they belong to the same material, plant, and storage location, and that they have the same valuation type.
  Process in Batches: If you need to adjust multiple lines, consider processing them in smaller batches that meet the criteria for adjustment.
