• What is the cause and solution for SAP error message VN002 - Enter a partner number ?

  SAP Error Message:
  
  VN002 - Enter a partner number
  
  Cause:
  The error message VN002 occurs when a required partner number is missing in a transaction or document. In SAP, business partners (such as vendors, customers, or employees) are often assigned partner functions (e.g., ordering address, invoicing party). If the system expects a partner number for a specific partner function but none is entered, it triggers this error.
  Common scenarios include:
  
  Creating or changing purchasing documents (e.g., purchase orders, contracts) where a partner function is mandatory but no partner number is provided.
  Vendor master data or partner determination procedures require a partner number for certain partner roles.
  Partner determination configuration expects a partner number but it is not maintained or passed.
  
  
  Solution:
  
  
  Enter the required partner number:
  
  Identify the partner function for which the partner number is missing and enter the correct partner number (e.g., vendor number, customer number).
  
  
  Check partner determination procedure:  
  
  Go to the relevant customizing transaction (e.g., SPRO ? Materials Management ? Purchasing ? Partner Determination) and verify if the partner function is set as mandatory.
  If the partner function is mandatory, ensure that the partner number is maintained in the document or master data.
  
  
  
  Maintain partner data in the document:  
  
  In the transaction where the error occurs (e.g., ME21N for purchase order), navigate to the "Partners" tab and enter the missing partner number.
  Save the document after entering the partner number.
  
  
  
  Review master data:  
  
  Check if the partner number exists and is valid in the master data (e.g., vendor master).
  If missing, create or update the master data accordingly.
  
  
  
  Check user exits or custom code:  
  
  Sometimes, custom validations or user exits enforce partner number entry. Review any custom code if standard solutions do not resolve the issue.
