How To Fix SWDP_WB_TOOL465 - Context structure does not match form interface of "&1"

SAP Error Message - Details

• Message type: E = Error

• Message class: SWDP_WB_TOOL - Web Dynpro: Messages for Workbench Tools

• Message number: 465

• Message text: Context structure does not match form interface of "&1"

What causes this issue?

The context structure is incompatible with the form interface.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

In an interface with DDIC parameters, this can have the following
consequences:
- Name discrepancy (possibly caused by renaming an
attribute/node)
- Inconsistences in typing (possibly caused by deleting and
recreating an attribute
with a different typing).
- Inconsistencies in the node properties (possibly due to
incorrect cardinality or selection)
- There are elements in the context that do not match the
parameter structure of the interface. This can result in
a termination during runtime.
In an interface based on an XML schema, this means that the schema found
for the bound context is not the same as the one set for the existing
interface. However, this does not necessarily mean that an error has
actually occurred (especially when dealing with schemas that were not
originally generated from a Web Dynpro Context).

System Response

How to fix this error?

You can resolve the problem by running the repair function, provided
that this is offered.
Alternatively, you can use the context menu functions offered for UI
element "Interactive Form" in order to regenerate the context or XML
schema of the interface.
Warning: Note that the repair function (or the corresponding context
menu function) builds the context completely in exactly the same way as
the interface parameters, and that you might have a radically different
number of elements in the context after carrying out the repair.
A newly generated schema interface may affect other form objects that
use this interface.
If you are familiar with the interface structure, you also have the
option of solving this problem manually.
