• What is the cause and solution for SAP error message 29647 - EC management only supported for BOM maintenance with validity ?

  The SAP error message 29647, which states "EC management only supported for BOM maintenance with validity," typically occurs in the context of Bill of Materials (BOM) management when trying to perform Engineering Change Management (ECM) operations on a BOM that does not have validity dates set.
  Cause:
  The error arises because the Engineering Change Management functionality in SAP requires that the BOM has validity periods defined. This means that the BOM must have a start date and an end date (or an indefinite end date) to manage changes effectively. If these validity dates are not set, the system cannot process the ECM operations, leading to this error message.
  Solution:
  To resolve this error, you need to ensure that the BOM you are trying to work with has the necessary validity dates defined. Here are the steps to do this:
  
  
  Access the BOM Maintenance Transaction:
  
  Use transaction code CS02 (Change BOM) or CS01 (Create BOM) in SAP.
  
  
  
  Select the BOM:
  
  Enter the relevant material number and plant to access the BOM in question.
  
  
  
  Set Validity Dates:
  
  In the BOM header, look for the fields related to validity dates (e.g., Valid From and Valid To).
  Set the "Valid From" date to the date when the BOM should become effective.
  Optionally, set the "Valid To" date if you want to specify an end date for the BOM's validity.
  
  
  
  Save the Changes:
  
  After entering the validity dates, save the BOM.
  
  
  
  Retry the ECM Operation:
  
  Once the BOM has the validity dates set, you can retry the Engineering Change Management operation that previously resulted in the error.
  
  
  
  Related Information:
