Reverse Button

Hi All

I have case from GL Entries

I have Batch 1300 and more some entries

I already post this and already look at GL Transaction Listing, we get that amount from this batch-entry

But i want reverse 1 entry, i open GL Batch List dan look to batch-entry

Why i can not found reverse button for that entry? i look the other entries have reverse button.

this entry not error, and i can find that transaction at GL Account History, Transaction listing

Any solutions?
