Internal table export and import in ECC 5.0 version

Question

Hi friends,
I am trying to export and import internal table from one program to other program.
The below… export and import commands are not working when I run the program in background (using SUBMIT zxxxx via JOB name NUMBER number…..)
EXPORT ITAB TO MEMORY id 'ZMATERIAL_CREATE'.
IMPORT ItAB FROM MEMORY ID 'ZMATERIAL_CREATE'.
Normally it should work. Since It’s not working I am trying with another alternative..
i.e EXPORT (ptab) INTERNAL TABLE itab.
My sap version is ECC 5.0….
For your information, here I am forwarding sap help. Pls have a look and explain how to declare ptab internal table.
+Extract from SAP help+
In the dynamic case the parameter list is specified in an index table ptab with two columns. These columns can have any name and have to be of the type "character". In the first column of ptab, you have to specify the names of the parameters and in the second column the data objects. If the second column is initial, then the name of the parameter in the first column has to match the name of a data object. The data object is then stored under its name in the cluster. If the first column of ptab is initial, an uncatchable exception will be raised.
Outside of classes you can also use a single-column internal table for parameter_list for the dynamic form. In doing so, all data objects are implicitly stored under their name in the data cluster.
My internal table having around 45 columns.
pls help me.
Thanks in advance

The export/import should work the way you are using it. Just make sure you are using same memory id and make sure its unique - meaning u are using it only for this itab purpose and not overwriting it with other values. Check itab is not initial before you export in program 1 - then import it in prog2 with same memory id...also check case, I am not sure if its case sensitive...
Here is how you use the second variant...
Two fields with two different identifications "P1" and "P2" with the dynamic variant of the cluster definition are written to the ABAP Memory. After execution of the statement IMPORT, the contents of the fields text1 and text2 are interchanged.
TYPES:
  BEGIN OF tab_type,
    para TYPE string,
    dobj TYPE string,
  END OF tab_type.
DATA:
  id    TYPE c LENGTH 10 VALUE 'TEXTS',
  text1 TYPE string VALUE `IKE`,
  text2 TYPE string VALUE `TINA`,
  line  TYPE tab_type,
  itab  TYPE STANDARD TABLE OF tab_type.
line-para = 'P1'.
line-dobj = 'TEXT1'.
APPEND line TO itab.
line-para = 'P2'.
line-dobj = 'TEXT2'.
APPEND line TO itab.
EXPORT (itab)     TO MEMORY ID id.
IMPORT p1 = text2
       p2 = text1 FROM MEMORY ID id.
