abstract = {We continue to investigate which polynomials can possibly
occur as factors in the denominators of rational solutions
of a given partial linear difference equation. In an earlier
article we have introduced the distinction between periodic
and aperiodic factors in the denominator, and we have given
an algorithm for predicting the aperiodic ones. Now we extend
this technique towards the periodic case and present
a refined algorithm which also finds most of the periodic
factors.},
