cost center mapping with same profit center

Hi, Experts

I am getting error in MIGO screen, that Account required CO object in GL account level.

I can give the cost center in the GL account level and solve the issue.

But I have different material masters laying on different cost centers, the end user are not in a position to know the cost centers.

I have maintained profit center in each material master.

I found that we can do the profit center cost center assignment in the OKB9 screen, but i cannot maintain the relation ship with multiple cost center with same profit center ?

how we can maintain such relation in  that cost center mapping with same profit center in OKB9 ?

regards,
