Solution 1

Check your sp.
There might be one subquery which returns more then one value.
when you are using =,<=,>=,!= operator on subquery then that subquery must return single value or else use In or Not In clause.

Solution 2

check sub-query it's returning more than one value,

Check filtering conditions of sub-query because after filtration it should return one value not multiple.
Use top 1 or distinct in your sub-query

Happy Coding!
:)

Check the subquery. You have many options.
1. Use in instead of =, not in instead of != and so on.
2. Use grouping like sum/count/avg/max/min/first
3. Use distinct or group by
4. Find the error in the subquery and correct it to return exactly one value.

I would say you'd rather have to check option 4. When a query returns more than one value in place where you need exactly one, means your query is not correct, and avoid options 1/2/3 unless this is exactly that you need.
