Authorization to run a bps function from web

Hi gurus,

We have a layout that the users will access from web. For this we have created a Web Interface. This layout has also a planning function that calls an abap program.

We have created a profile and the user is able to access and run that function from GUI, however from WEB that fuctions does not run the abap.

The user already have the following authorization objects: S_ICF, S_DEVELOP, R_BUNDLE, R_PLEVEL, R_WEBITF, S_RS_ICUBE, S_RS_IOBJ, but it looks like something is still missing.

I´d appreciate any help

Thanks,

Pablo
