This can happen for several reasons. Below are the potential causes, solutions, and related information for this error:
  Causes:
  
  No Sales Orders Exist: There may be no sales orders created for the material in question.
  Sales Order Status: The sales orders that exist may not be relevant for MRP due to their status (e.g., they may be in a closed or canceled status).
  MRP Type Configuration: The material may not be configured with an appropriate MRP type that considers sales orders (e.g., MRP type is set to "ND" - No MRP).
  Plant or Storage Location Issues: The material may not be assigned to the correct plant or storage location where the sales orders are created.
  Sales Order Item Category: The item category of the sales order may not be relevant for MRP.
  Date Issues: The delivery dates of the sales orders may be in the past or not aligned with the planning horizon.
  
  Solutions:
  
  Check Sales Orders: Verify that there are active sales orders for the material. You can do this by using transaction codes like VA03 (Display Sales Order) to check the status and details of the sales orders.
  Review MRP Type: Ensure that the material is assigned an appropriate MRP type that considers sales orders. You can check this in the material master (transaction MM03).
  Check Item Category: Ensure that the item category of the sales order is set to a category that is relevant for MRP (e.g., standard item category).
  Validate Plant and Storage Location: Confirm that the material is assigned to the correct plant and storage location where the sales orders are created.
  Adjust Planning Horizon: If necessary, adjust the planning horizon to ensure that it includes the delivery dates of the sales orders.
  Run MRP Again: After making the necessary adjustments, run the MRP process again to see if the error persists.
  
  Related Information:
  
  MRP Configuration: Understanding MRP types and their settings in the material master is crucial for effective planning.
  Sales Order Management: Familiarity with sales order processing and the implications of different item categories can help in troubleshooting.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MD01 (MRP Run), MD02 (MRP for Single Item), and MD04 (Stock/Requirements List) for monitoring and managing MRP processes.
  
  By addressing the above causes and implementing the suggested solutions, you should be able to resolve the MF336 error and ensure that MRP can find the relevant sales orders for planning purposes.
