Creating Z program for T code FBRA (resetting cleared item)

HI ABAP Gurus,

I have a requirement , please Help me.

One of my client Has executed APP program. through with 100 items are cleared. later they identified those invoice should not be cleared. To Reset this cleared item we have T code FBRA through which we can reset single line item each time.

So we need to develop a new program for Resetting all the items at one instance. Please guide how configure this??
