Calling Word long text editor SAP GUI: "Document interface not initialized" (SOFFICEINTEGRATION214)

[su01]

Update: Solution found

Problem:

When using Microsoft Word as long text editor (for creation of online help) in SAP GUI, the error "Document interface not initialized"(SOFFICEINTEGRATION214) is shown and SAP falls back to the old editor.

It's not SAP-system dependent as it happens with any system and release.

Solution

A (new?) office UI feature has to be deactivated:

Then Word is displayed as an embedded control in SAP GUI, instead of a stand alone window, and works again as an editor:

This seems to be a known issue:

The Microsoft page has a recent date and is for Office release 1806 or higher ( I am on 365 Version 2207 Build 16.0..... 32bit).
I couldn't find or identify this via intensive SNotes search.

Tested:

• on my Windows 10; Gui7.7 PL7; Office 365 Version 2207 Build 16.0..... 32bit;
• SolMan and some S4 system
• switching that setting back and forth, the GUI to Office Document Integration works or does not

Thanks. The solution totally works!

Although I try SAP GUI 8.00 64bit with Office 2021 64bit, the problem is there.
