how to list observation with "assertion is false"

[Irma Lukman]

Hello,
I am currently doing consistency checks in my dataset by enter this command

. assert inlist(fm03B,1,2,3,4,5,6,7) if fm02B==1
1 contradiction in 25989 observations
assertion is false
r(9);

result shows that there is one contradiction, what does it mean and how to know the observation that contradicts so I can drop it?
thank you

list if !inlist(fm03B,1,2,3,4,5,6,7) & fm02B==1
