Problem Note 56886: PROC MODEL might generate incorrect simulation values if the OPTIMIZE option is specified in the SOLVE statement
In PROC MODEL, if you specify a model equation that contains second order heterogeneous terms and you also specify the OPTIMIZE option in the SOLVE statement, the simulation results might be incorrect. An example of a second order heterogeneous model term is 3*x*y.

For software releases that are not yet generally available, the Fixed
Release is the software release in which the problem is planned to be
fixed.
PROC MODEL might produce incorrect simulation values if you specify the OPTIMIZE option in the SOLVE statement and you also specify a model equation containing second order heterogeneous terms.
