ITS returns 409 for ~okCodes specified in URL

Hi Folks,

we just had a HANA update with an upgrade to 7.40.

The problem is that the ITS / ICF behaves different now.

I had specified a ~okCode parameter In my service in SICF that was previously used as a fallback if no ~okCode parameter was used in the URL.

Now I can ONLY use that okCode at initialization at my application otherwise I get an 409 Server Response:

This is a huge problem to us because the link to the application without any ~okCode has been distributed a lot and changing all that location will take a huge effort and problems. And there are other calls that use a different ~okCode for initialization.

I also tried to use ~okcode_permit (note  1501768 ) but that didn't help.

How can I solve this or get rid of the restrictive okCode checking.

Thx for your support!
