Hi Swati,
I would regenerate the query in RSRT.
Then open the query in query designer and check it there, maybe it gives any error messages.
Since the error message points to
CL_RSR_TIME_RELATION_HDB
and ypu talk about an input ready query, you should check for any inconsistencies in your data model regarding time char, char relationships and the data that you are reading. It´s hard to tell as long as we dont know what data you are reading, what the query does, how the data model is defined ...
regards
Cornelia
