Need to concatenate Sales Order and Item

Hi,

I got a requirement to concatenate Sales Order and Item in an InfoObject. So i have written a field routine and removed the standard FM to remove the zeroes in Order and Item. Then in the result I made the concatenation.

But while loading data, it took maximum time to process each Data Package. Is there any other way to achieve this requirement.

Kindly share your thoughts.

Thanks,

Satish.
