• What is the cause and solution for SAP error message FDT_DEPLOYMENT122 - Incompatible element &1: New value list with active existence check ?

  The SAP error message FDT_DEPLOYMENT122 indicates that there is an issue with the deployment of a field or element in the context of a data model or form. Specifically, the error message states that there is an "Incompatible element" due to a "New value list with active existence check." This typically occurs when there is a mismatch between the expected values for a field and the values that are being provided or defined in the system.
  Cause:
  
  Incompatible Value List: The error usually arises when a new value list is being deployed for a field that has an active existence check. This means that the system is trying to validate the values against a list that is not compatible with the existing configuration.
  Changes in Data Model: If there have been recent changes to the data model or the value list that are not aligned with the existing definitions, this can trigger the error.
  Active Existence Check: The existence check is a validation mechanism that ensures that the values being entered or processed exist in a predefined list. If the new value list does not match the expected values, the error will occur.
  
  Solution:
  
  Review Value Lists: Check the value lists associated with the field that is causing the error. Ensure that the new value list is compatible with the existing definitions and does not conflict with the active existence check.
  Adjust Existence Check: If necessary, modify the existence check settings to accommodate the new value list. This may involve updating the configuration to ensure that the new values are recognized by the system.
  Re-deploy the Data Model: After making the necessary adjustments, re-deploy the data model or the specific field to ensure that the changes take effect.
