How To Fix WZ327 - Errors in parameter values for method 'process'

WZ327 - Overview

• Message type: E = Error

• Message class: WZ - Workflow: Model objects

• Message number: 327

• Message text: Errors in parameter values for method 'process'

What causes this issue?

The method parameters <ZH>R3FForm</>, <ZH>R3FFormType</> or <ZH>work
item</> have no values.

System Response

The method <ZH>Process</> of the object type <ZH>FORM</> or a
<DS:GLOS.36AAA2749235503BE10000009B38F9B6>subtype</> cannot be
executed.

How to fix this error?

Ensure that all the parameters have values. If you use the method in
execution of the work item, you need the following binding from the
task container to the method container (note the third line in
particular):
R3FFORM,,<==,,<(>&<)>R3FFORM<(>&<)>
R3FFORMTYPE,,<==,,<(>&<)>R3FFORMTYPE<(>&<)>
WORKITEM,,<==,,<(>&<)>_WORKITEM<(>&<)>

• SAP Error Message:
  WZ327 Errors in parameter values for method 'process'
  
  Cause
  This error typically occurs in SAP Workflow when the method process is called with incorrect or invalid parameter values. The workflow runtime engine validates the parameters passed to the method, and if any parameter is missing, has an unexpected type, or contains invalid data, it raises this error.
  Common causes include:
  
  Incorrect binding of parameters in the workflow definition.
  Missing mandatory parameters for the method.
  Data type mismatches between the expected method parameters and the actual values passed.
  Inconsistent or incomplete data passed from the triggering event or preceding workflow step.
  Custom method implementations that expect specific parameter formats or values.
  
  
  Solution
  
  
  Check Parameter Bindings:
  
  Go to the workflow builder (transaction SWDD).
  Open the relevant workflow and locate the step where the method process is called.
  Verify the parameter bindings for the method. Ensure all required parameters are correctly bound to workflow container elements or constants.
  
  
  
  Validate Data Types:
  
  Confirm that the data types
