• What is the cause and solution for SAP error message DMEE348 - Node &1: date/time conversion only possible for data type "Character" ?

  The SAP error message DMEE348 indicates that there is an issue with the data type being used in a date/time conversion within the Data Medium Exchange Engine (DMEE). Specifically, the error states that the conversion can only be performed on data of type "Character." Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Incorrect Data Type: The error typically occurs when you attempt to convert a date/time value that is not in the character format. For example, if the input data is in a numeric format or another incompatible format, the conversion will fail.
  DMEE Configuration: The configuration of the DMEE tree might be set up incorrectly, where a node is expecting a character type input for date/time conversion but is receiving a different type.
  
  Solution:
  
  Check Data Types: Review the data being passed to the node that is causing the error. Ensure that the data type is indeed character. If it is not, you may need to convert it to a character format before it reaches the conversion node.
  Modify DMEE Tree: If the DMEE tree is incorrectly configured, you may need to adjust the settings:
  
  Open the DMEE tree in transaction code DMEE.
  Locate the node that is causing the error.
  Ensure that the input to this node is set to a character type. You may need to use a conversion function or a mapping to ensure the data is in the correct format.
  
  
  Use Conversion Functions: If you are working with date/time values, consider using conversion functions available in DMEE to convert the data to character format before performing any operations on it.
  Testing: After making changes, test the DMEE output to ensure that the error is resolved and that the output is as expected.
  
  Related Information:
  
  DMEE Documentation: Refer to the official SAP documentation for DMEE for detailed information on how to configure and troubleshoot DMEE trees.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance on handling data types in DMEE.
  Community Forums: Consider searching or posting on SAP community forums or platforms like SAP Community, where other users may have encountered and resolved similar issues.
  
  By ensuring that the data types are correctly configured and that the input to the conversion node is in the expected format, you should be able to resolve the DMEE348 error.
