• What is the cause and solution for SAP error message CPE_ERP143 - Only one item per PO item is allowed in CPE ?

  The SAP error message CPE_ERP143: Only one item per PO item is allowed in CPE typically occurs in the context of the SAP Converged Procurement Engine (CPE) when there is an attempt to create or process a Purchase Order (PO) that violates the system's constraints regarding item handling.
  Cause:
  This error generally arises due to the following reasons:
  
  
  Multiple Items in a Single PO Item: The system is designed to allow only one item per PO item. If you attempt to add multiple items to a single line item in the PO, this error will be triggered.
  
  
  Incorrect Data Entry: There may be a mistake in how the PO is being created, such as inadvertently adding multiple materials or services to a single line item.
  
  
  Configuration Issues: There could be configuration settings in the CPE that enforce this rule, which may not align with the way the PO is being structured.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the PO Structure: Check the Purchase Order you are trying to create or modify. Ensure that each line item corresponds to a single material or service. If you have multiple items, create separate line items for each.
  
  
  Correct Data Entry: If you find that multiple items were mistakenly added to a single line, remove the extra items and ensure that each line item is unique.
  
  
  Consult Documentation: Review the SAP documentation or guidelines related to the CPE to understand the constraints and best practices for creating POs.
  
  
  Configuration Check: If you believe the configuration might be causing this issue, consult with your SAP administrator or technical team to review the settings in the CPE.
