I get the following error "THIS can only be used within a method" on the locate statement if I add a filter to the table. Is this not possible to do? If I then run the same code without the filter I do not get the error.

If you set filter using some form's custom property, e.g.
SET FILTER TO myfield=thisform.myproperty
then it goes out of scope when you call external Prg. Naturally enough it happens when VFP tries to move record pointer (Locate) and apply filter.
