Standard communication method

Hello,

We are Creating BP in ISU system using FM :- ISU_S_PARTNER_CREATE

The BP is getting created successfully in ISU system. But if i pass value into COMM_TYPE then the standard communication method is not getting populated in the BP tcode.

ISU_S_PARTNER_CREATE has importing parameter x_auto which is a deep structure. In this structure there are 2 possible fields to pass COMM_TYPE

1. x_auto-act-DEFLT_COMM

2. x_auto-t_adrt_mod-COMM_TYPE

I tried passing 'FAX' to both these field but once the BP was created in ISU, the Standard commuication method field in BP tcode was still blank.

Could you please help me to fix this issue.

Thanks,

Darshan
