EKKO EKPO EKET join BODS3.1

Hi,

We are developing a GR interface in BODS 3.1. Kindly find attached the strategy for it. We are trying to pull MSEG,MKPF,MCHA,EKKO,EKPO,EKET,EKBE, EBAN TABLE join to fetch the data monthwise and saved in SQL server 2005. As we know these tables contained huge data(more than 10 million). we break the joins but still we are getting session time out issue. For testing we join only ekko,ekpo,eket table and try to pull one month data in one data flow. But no luck. Can anybody help me?

Regards,

Nikhil
