AIF customizing screen not allowing to use /TMINT namespace to integrate FreightOrder proxy

[HarikaBonala]

I am trying to integrate SAP TM Freight order standard proxy ( TransportationOrderGenericRequest_In ) to process errors to AIF. Below screen shot is the standard proxy runtime class where we have logic to integrate to AIF.

It has inbuild AIF namespace and Interface name details in the proxy. I am trying to create the given name space /TMINT using /AIF/CUST. I get below error; we cannot save this namespace.

Any suggestions on how to save the namespace or any other approach to achieve this scenario.

SAP On Premise, right? You may Unlock the namespace using transaction /AIF/NS_LOCK. And you have to understand '/' is reversed for SAP https://me.sap.com/notes/3071632/E.
