Creating Change History Documents in SRM

Hi,

I am needing to update some flags in BBP_PDPSET and am having to do a direct table update since BBP_PD_PO_UPDATE did not work.  What I need to do now is to is create change history documents for these flags.  I know how to do it in ECC but not SRM.  What FM, object, program would I need?

Thanks,

Susie
