To get a sequence between multiple variables

[Jimmy9]

Data test2;
set test1;
by SUB visit date testcd;

if first.date = 1 then seqvale + 1;

run;

I want to have seqvale per sub,per visit , per date and testcd

That's a very brief explanation, but I think what you want is

if first.testcd = 1 then seqvale + 1;

If that's not what you want, please explain in much more detail.
