• What is the cause and solution for SAP error message COM_PRODUCT034 - Object family cannot be changed ?

  The SAP error message COM_PRODUCT034 indicates that the object family of a product cannot be changed. This typically occurs in the context of SAP's Product Lifecycle Management (PLM) or similar modules where product data is managed.
  Cause:

  Check Object Status: Ensure that the product is not in a status that prevents changes. If it is locked or in use, you may need to wait until the process is complete.
