Manual Batch number with space

Dear Gurus,

While making GRN of raw material my user received material with batch number (manual batch), he make a space before batch number, let say batch number is 321, he enter 321 but before 3 make a space in the field.

now at the time of consuming system don't recognize it even with the space as well, posting period already close.

please suggest how i will over come this issue with thanks.

regards,
