Unable to import Product Categories from ECC to SRM7.0

Hi Experts,

I am unable to import Product Categories from ECC to SRM7.0. I have set up settings correctly and when started initial load, I got the message like imports process is running. But when I checked in R3AM1, it seems "Running" but when I double click it is showing "Sys fail", the following is the error.

SMQ1: The current application triggered a termination wi th a short dump.

Message no. SR053

When I looked at the dump, I see the following:

ST22: Internal error in the spool system

ST22: Error in the SAP kernel.

ST22: The current ABAP "BBP_GET_STATUS_2" program had to be terminated because the

ABAP processor detected an internal system error.

I tried searching old issues posted in forum, but really could not understand.

Request your help.

Thanks & Regards
