Data Mart in Process chains

Hi Gurus,

I am using a standard ODS for FI_AR and also the standard FI_AR cube which recieves data from this ODS.

I have created a process chain for dataloading in ODS and the subseuqent process that is data mart from ODS to cube is failing in Process chain.

Could anyone guide me how to include this further processing i.e from ODS to CUBE loading process in Process chain.

Thanks in advance.

Regards,

Satya
