I came acrross many SDN posts where the common questions is "How to check for queries where my varaible is getting used'.
This blog will give you the solution how we can find the queries and views where particular variable being used.
One standard is way to find this one is through where used list in the query but with this you can not save result at all.
Here is the easy way where you can save the references.
you can simply use SAP Function RRM_SV_VAR_WHERE_USED_LIST_GET
where you need pass UID of variable as paramter then you will get where used list.
