Here is my query on Short Dump in BW.
Dump Name: OBJECTS_OBJREF_NOT_ASSIGNED
Attempt to access a component using 'NULL' object reference (points to nothing).
An object reference must point to an object (an instance of a class)
before you can use it to access components (variable: " ").
Either the reference has not yet been set, or it has been reset to
'NULL' by a CLEAR statement.
"SAPLRSDBC" or "LRSDBCU06"
Pls help me to solve this dump if anybody face the same dump before.
