I am having a problem with proc tabulate. A sample table specification is below:

Table q, a*b,c*(N*f=3.);

My problem is that all possible combinations of a*b may not occur at each level of q. Thus, a table might look like this:

q a b c1 c2 1 1 1 3 3 1 2 6 9 2 1 1 10 2 2 3 5

2 1 1 8 3 2 1 1 10 2 2 3 5

How can I specify the table so that I get

q a b c1 c2 1 1 1 3 3 1 2 6 9 2 1 1 10 2 2 3 5

2 1 1 8 3 1 2 . . 2 1 1 10 2 2 3 5

Thanks in advance.
