  The SAP error message WRF_PRC_POHF156 indicates that you are trying to block or unblock a subitem in a purchase order (PO) or a related document, but the system only allows this action for main items. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  The error occurs because the action you are attempting (blocking or unblocking) is only applicable to main items in the purchase order. Subitems are typically dependent on their main items and cannot be individually blocked or unblocked.
  
  Solution:
  
  
  Identify the Main Item: Check the purchase order to identify the main item associated with the subitem you are trying to block or unblock.
  
  
  Block/Unblock the Main Item: Instead of trying to block or unblock the subitem, perform the action on the main item. This can usually be done in the purchase order screen by selecting the main item and using the appropriate function to block or unblock it.
  
  
  Review Item Structure: If you need to manage subitems, ensure that you understand the structure of your purchase order and how main items and subitems are related. This will help you manage them effectively.
  
  
  Consult Documentation: If you are unsure about the process, refer to SAP documentation or your organization's SAP guidelines for managing purchase orders and item statuses.
  
  
  User Permissions: Ensure that you have the necessary permissions to block or unblock items in the purchase order. If you do not have the required permissions, contact your SAP administrator.
  
  
  Related Information:
  
  SAP Transaction Codes: Familiarize yourself with relevant transaction codes such as ME22N (Change Purchase Order) or ME23N (Display Purchase Order) to manage purchase orders effectively.
  SAP Notes: Check for any SAP Notes related to this error message for additional insights or updates from SAP.
  Training and Support: If you frequently encounter issues with purchase orders, consider seeking additional training or support from your SAP team or through SAP Learning Hub.
