<DYNAFILE> use requires the <ALLOCATE> tag.
What happened: Your Output group included the <DYNAFILE> tag, but did not include the <ALLOCATE> tag.
What to do: Either remove the <DYNAFILE> tag and add a <FILE> tag to your Output group; or add an <ALLOCATE> tag with the proper file allocation standards for your dynamic file allocation.
