• What is the cause and solution for SAP error message BSP_DLC_TOOLS018 - 'Mandatory' and 'Display Only' cannot be set at the same time ?

  The SAP error message BSP_DLC_TOOLS018 indicates a conflict in the configuration of a Business Server Page (BSP) application. Specifically, it arises when both the 'Mandatory' and 'Display Only' properties are set for the same input field in a BSP application. This is not allowed because a field cannot be both mandatory (requiring user input) and display-only (not allowing user input) at the same time.
  Cause:
  
  The error occurs when a developer or user attempts to configure a field in a BSP application to be both mandatory and display-only. This typically happens during the design phase of the BSP application when defining the properties of input fields.
  
  Solution:
  
  
  Review Field Properties: Check the properties of the input field that is causing the error. You need to decide whether the field should be mandatory or display-only based on the business requirements.
  
  
  Adjust Configuration:
  
  If the field should accept user input, set it as Mandatory and ensure that the Display Only property is not checked.
  If the field should not accept user input and is meant for display purposes only, set it as Display Only and ensure that the Mandatory property is not checked.
  
  
  
  Test Changes: After making the necessary adjustments, test the BSP application to ensure that the error no longer occurs and that the field behaves as expected.
  
  
  Related Information:
