BAPI like profile

Hi all,

I need a BAPI/FM that allows me to create like profiles (TC: /SAPAPO/MSDP_FCST1). I found FM /SAPAPO/FCST_LIKE_PROFILE_SAVE, but relative GUID is not generated and so tables /SAPAPO/T445LIKK and /SAPAPO/T445LIKT are populated with a blank likeid*).

Thanks.

*OT: is there any FM that generates GUID?

EDIT: CALL FUNCTION 'GUID_CREATE'
