Batch input - FB05 - How to fill LIFNR if I post on GL account.

Hi, our company normaly use IDOCs (FIDCCP02) for posting FI documents (accrual intercompany FI documents) and there we can fill LIFNR and it is saved in BSEG-LIFNR. But now I created batch input for transactin FB05 and I cannot fill LIFNR anywhere on screen by FI document posting on GL account. Is there any option how to fill LIFNR in batch input when i post on GL account?

Thanks
