Import/export not working as expected

Question

Following is my code.

data:itab_bapiname like ztransform occurs 10 with header line.

The section under consideration ive made bold and italised it.
Im calling another program dynamically and in that program im exporting some date to the sap memory.However when i import it from my program im unable to view the values. Why is that?

Hi Friend,
Below is an example for successfully using IMPORT and EXPORT:
IMPORT ws_samepo TO loc_x FROM MEMORY ID 'SAMEPO'.*
EXPORT ws_samepo = loc_x TO MEMORY ID 'SAMEPO'.
Pleaes use same variable name for IMPORT and EXPORT.
Hope it will help you.
