• What is the cause and solution for SAP error message CNV_OM035 - Select at least one valid line item. Generation state must be non-initial ?

  The SAP error message CNV_OM035 ("Select at least one valid line item. Generation state must be non-initial") typically occurs in the context of data migration or conversion processes, particularly when using the SAP Conversion Tools or during the execution of a migration project.
  Cause:
  This error generally indicates that the system expects at least one valid line item to be selected for processing, but none have been selected or the selected items are in an invalid state. The "generation state must be non-initial" part of the message suggests that the process requires a certain state of data that has not been met, possibly due to:
  
  No Selection Made: The user has not selected any line items for processing.
  Invalid State: The selected line items may be in an initial or unprocessed state, which is not acceptable for the operation being performed.
  Data Integrity Issues: There may be issues with the data integrity or completeness, leading to the inability to select valid line items.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Select Valid Line Items: Ensure that you have selected at least one valid line item in the relevant screen or transaction. Check the selection criteria and make sure that the items you want to process are highlighted.
  
  
  Check Generation State: Verify the generation state of the line items. If they are in an initial state, you may need to process them further or change their state before they can be selected for the operation.
  
  
  Review Data: Check the data for completeness and integrity. Ensure that all required fields are filled out and that there are no inconsistencies in the data that could prevent valid line items from being selected.
  
  
  Consult Documentation: Refer to the SAP documentation or help resources related to the specific migration or conversion tool you are using. There may be specific prerequisites or steps that need to be followed.
  
  
  Check User Authorizations: Ensure that you have the necessary authorizations to perform the operation. Lack of permissions can sometimes lead to unexpected behavior.
  
  
  Contact Support: If the issue persists after checking the above points, consider reaching out to SAP support or your internal IT team for further assistance. They may have additional insights or tools to diagnose the problem.
