CRM-IPM Due List Item(DLI) is not generated

HI All,

I created IPM sales contract and resistered Confirmation data(Tr-cd:CRM_IPM_D_USAGE_DATE),

but whenI try to see process billing due list(Tr-cd:/BEA/IPMI01) no data found.

I use CRM standalone system. To generate DLI, should I need to integrate ERP?

Are there anyone succeed to generate BLI in CRM standalone system ?

thanks in advace
