Use the BACKREf Attribute *12​.1​.SP3*

The BACKREf attribute brings the back pointer reference for Reference Table Attributes and answer the question "what references me (ce)". The syntax is:

Q BACKREF [(ATTNAME att1 [, ATTNAME att2] )]

for example, standing on a SPCO and querying for BACKREf (attname SPREF ) will return all elements referencing that SPCO.

Q BACKREF( attname SPCO)

Excluding the argument will list all Reference Table Attributes referencing CE. for example,:

Q BACKREF
