HTTP-Method not allowed ... no luck with nw gateway function import

[former_member558849]

Hi Netweaver experts.

Since today I am plagued by an incomprehensible problem with netweaver gateway function
imports.

Every call ends immediately with the indication that the http method is not allowed:

I tried out several combinations. PUT with/without parameters. POST also with and without parameters.

if anybody knows this kind of problem, please help. i already tried:

1. regeneration of dpc & mpc
2. clear model cache (fnd + bep)

POST is not allowed if the return type is 0..n or 1..n
