What causes this issue?

The transfer format or the transfer format group has changed in the
initiating Web activity that also fills the workflow proxy.
The current step that works on the basis of the workflow proxy has the
same transfer format. Therefore, the transfer format/transfer format
group must be transferred from the initiating Web activity.

Transfer takes place automatically and in certain circumstances the
function entered is also replaced by another. Note that technical
parameter settings can be lost.
If you do not agree with the changes, leave the step by choosing
<ZK>Cancel</> and use the original transfer format again in the initial
Web activity.

• What is the cause and solution for SAP error message WD387 - Transfer format/group applied from proxy; see the long text ?

  The SAP error message WD387 with the text:
  "Transfer format/group applied from proxy; see the long text"
  typically occurs in the context of Web Dynpro ABAP applications, especially when dealing with data transfer between components or proxies.
  
  Cause
  This message is informational and indicates that a transfer format or transfer group has been applied from a proxy object during the data transfer process. It usually appears when the system uses a proxy to transfer data between Web Dynpro components or between a Web Dynpro component and an external service.
  
  The transfer format/group controls how data is serialized and deserialized during the transfer.
  The message is triggered when the system detects that the transfer format/group is being applied from the proxy object rather than from the local component or context.
  It is often related to the use of component controllers, interface controllers, or context mapping where proxies are involved.
  
  
  Solution
  Since WD387 is generally an informational message rather than an error, it does not necessarily indicate a problem that needs fixing. However, if this message is causing confusion or is part of a larger issue, consider the following:

  Context Mapping
  
  Check the context mapping between components or between the component and the proxy. Ensure that the data structures and transfer formats are compatible.
  
  
  Debugging
