Imp error: ORACLE error 1400 encountered

[mahajanakhil198]

Dave and PAVB, I understood.

I separately created the table MAM_ASSETS and removed NOT NULL from problematic columns. Then I used ignore=y option to import. But somewhere while importing, it creates NOT NULL constraints on these columns and I again start receiving the same error.

What can I do here? How could I remove the code from import that creates NOT NULL constraints?

Or as a workaround, I am able import only MAM_ASSETS table. But now the problem is that I don't want to import MAM_ASSETS while importing the rest of schema. IMP doesn't provide something like exclude as in IMPDP.
