• What is the cause and solution for SAP error message VK178 - Rebate agreement & already exists ?

  The SAP error message VK178 indicates that a rebate agreement already exists for the specified conditions. This typically occurs when you attempt to create a new rebate agreement that overlaps with an existing one, either in terms of the customer, material, or other relevant criteria.

  Duplicate Agreement: The most common cause is that there is already an active rebate agreement for the same customer and material combination or for the same validity period.
