how to get the specific abap from a given memory id

hi ,

if we have IMPORT statement with a specific memory id in an ABAP, then how do we find out the EXPORT statement belonging to that memory id ???

for eg: consider a abap XYZ where we have a statement like :

IMPORT WORKTAB FROM MEMORY ID 'YSYPARACOMP'.

where the memory id is : YSYPARACOMP

now my question is " HOW DO WE KNOW FROM WHICH ABAP THIS MEMORY ID HAS BEEN EXPORTED??? "

or do we have ant standard trnsaction code for it ??

a quick response on this will be highly appreciated.

With best regards

Thrivikram,
