Error: Lookup Transformations <transformation name> and <transformation name> have the same cache file name prefix <cache file name> but correspond to different tables <table name> vs. <table name>.
Two Lookup transformations use different lookup tables, but have the same cache file name.
If you want to share the cache, the lookup table names must match. If you do not want to share the cache, change the cache file name for one of the Lookup transformations.
