• What is the cause and solution for SAP error message WER074 - FDT type &1 does not exist; check the code ?

  SAP Error Message:
  
  WER074 FDT type &1 does not exist; check the code
  
  Meaning / Cause:
  The error message WER074 indicates that a Field Data Type (FDT) specified in your code or configuration does not exist in the SAP system. The placeholder &1 will be replaced by the actual FDT type name that the system could not find.
  This typically occurs when:
  
  You reference a Field Data Type that has not been created or activated in the system.
  There is a typo or incorrect name in the code or configuration referring to the FDT.
  The FDT was deleted or is missing due to transport or system inconsistencies.
  You are working with custom or newly created FDTs that have not been properly maintained.
  
  
  Where does this happen?
  
  In Workflow development, especially when working with Workflow Container Elements.
  When defining or using Field Data Types in Business Object Repository (BOR) or Object Types.
  During ABAP development or configuration involving data types.
  In Workflow Builder or Workflow Editor when assigning container elements or parameters.
  
  
  How to check and solve the issue:
  
  
  Check the FDT name:
  
  Verify the exact name of the Field Data Type used in your code or workflow container.
  Make sure there are no typos or case mismatches.
  
  
  
  Verify existence of the FDT:
  
  Use transaction SWO1 (Business Object Builder) or SE11 (Data Dictionary) to check if the FDT exists.
  In SWO1, check the container elements and their data types.
  In SE11, check if the data type is defined as a data element, structure, or domain.
  
  
  
  Create or activate the missing FDT:
  
  If the FDT does not exist, create it in the appropriate transaction (e.g., SE11 for data elements or structures).
  If it exists but is inactive, activate it.
  
  
  
  Check transport and system consistency:
  
  If the FDT was recently transported, ensure the transport was successful.
  Check if the FDT exists in the current system client.
  
  
  
  Review the code or workflow container:
  
  If the FDT is referenced in custom code or workflow container elements, correct the reference.
  Adjust the container element data type to a valid existing FDT.
  
  
  
  Check SAP Notes and documentation:
  
  Sometimes, this error can be related to specific SAP versions or patches.
  Search SAP Support Portal for notes related to WER074.

  You have a workflow container element defined as type ZMY_FDT_TYPE.
  When activating or running the workflow, you get error WER074: "FDT type ZMY_FDT_TYPE does not exist; check the code".
  You check in SE11 and find that ZMY_FDT_TYPE is not defined.
  You create the data element or structure ZMY_FDT_TYPE and activate it.
  The error disappears.
