Basically, subscreens don't manage the ok_code (usual trick is to use, and reset, sy-ucomm in those subscreen logic.
There you didn't clear it so an ok_code related to your table control was transmited to main (standard) dynpro, and this dynpro didn't expect this value. T185V = "Screen sequence control: Processing location(s)", the program didn't find exact value, so tried with some ("*") generic values.
