IDT Universe on OLTP Database

hello guys,

i am developing a universe on OLTP database in IDT.

So far, universe was looking complete.

But now issue which i am facing is-

suppose we have 2 tables a & b.

for 1 report, we have inner join btw these 2 tables but for other report, we need left join btw these 2 same tables for other report, it can be full outer join.

is there any way, we can sort such issues.
