  SAP Error Message: VP123
  Message Text:
  
  "Enter personnel numbers and contact persons in other block"
  
  Cause
  This error typically occurs in the SAP Sales and Distribution (SD) module, specifically when maintaining or processing business partner data or customer master records (e.g., in transaction VD01/VD02/VD03 or similar).
  
  The system expects that personnel numbers (e.g., sales employees, contact persons) must be entered in a different screen block or tab than the one currently being processed.
  The error arises because the user is trying to enter or maintain personnel numbers or contact persons in a block or screen where it is not allowed or expected.
  It can also occur if the system configuration requires that contact persons or personnel numbers be maintained in a specific section (e.g., the "Contact Persons" tab) but the user is trying to enter them elsewhere.
  
  
  Solution
  
  
  Check the Screen Layout:
  
  Navigate to the correct tab or block where personnel numbers and contact persons are maintained.
  For example, in the customer master, contact persons are usually maintained under the "Contact Persons" tab or block.
  
  
  
  Enter Data in the Correct Block:
  
  Do not enter personnel numbers or contact persons in the general data block or other unrelated blocks.
  Use the designated screen area for contact persons.
  
  
  
  Verify Customizing Settings:
  
  Check if the screen layout or field selection has been customized in Transaction OVA8 or related customizing transactions.
  Ensure that the fields for personnel numbers/contact persons are assigned to the correct screen blocks.
  
  
  
  Check User Exits or Enhancements:
  
  Sometimes, custom code or user exits might enforce additional validations causing this error.
  Review any custom developments related to customer master or business partner maintenance.
  
  
  
  Use Standard Transactions:
  
  Use standard SAP transactions for maintaining contact persons, such as VD01/VD02/VD03 for customers or BP transaction for business partners.
  Avoid entering personnel numbers in non-standard ways.
