Query with SQL-SP gives error, if not used for few days

Question

Hi All,
I have observed that if we do not use some of queries (which usage SQL SPs) for few days, then it stops working.
But when we go in SQL and execute the SP, the query in SAP starts working, without making any change either in query or the SQL-SP.
Can anybody throw light on this ? I guess it has some connection with SQL-SP behaviour.
Thanking you in advance ,

Hi Gordon,
Please note the function of the SP is to bring selected data from tables, for example to bring Purchase details (I have copy pasted the SP at bottom of this message).
These are not SP_notif...
These SPs are called from the SBO query.
Once we execute the SP in SQL, then it starts working with SBO also.
