• What is the cause and solution for SAP error message UDMO_CWL_MSG001 - You can only use filter &1 as a parameter (single value) ?

  The SAP error message UDMO_CWL_MSG001 indicates that you are trying to use a filter parameter in a way that is not allowed. Specifically, the message states that you can only use a single value for the specified filter parameter (denoted as &1). This typically occurs in the context of data extraction or reporting where certain filters are expected to be single-valued.
  Cause:
  
  Multiple Values Provided: The most common cause of this error is that the filter parameter you are using is set to accept only a single value, but you have provided multiple values (e.g., a range or a list).
  Incorrect Configuration: The configuration of the data extraction or reporting tool may not be set up correctly, leading to the system expecting a single value.

  Solution:
  
  Check Filter Input: Review the input for the filter parameter in question. Ensure that you are only providing a single value as required. If you need to filter by multiple values, check if there is an alternative way to do so (e.g., using a different parameter that allows multiple values).
  Modify Selection Criteria: If you are using a selection screen or a report, modify the selection criteria to ensure that only one value is being passed for the filter parameter.
  Consult Documentation: Refer to the documentation for the specific transaction or report you are using to understand the expected input for the filter parameters.
  Check Configuration: If you have access to the configuration settings, verify that the filter parameters are set up correctly and that they align with the expected input types.
