GL Listing with populated plant field

Hi all,

In GL listing (T-code-FBL3n) for Sales account-GL there is provision to see the line items detail of Sales Account with Plant as field, but I am seeing the GL line items without Plant field populated, How this field can be automatically populated as this acounting line item automatically gets created as soon as we save Billing document(VF01) and posted to proper GL.

Kindly help me to populate the Plant field.

Thanks in advance....
