FBL3N- GR/IR account

Hi All,

I have two issues in my project regarding GR/IR

1. GR/IR account shows some closing balance in FBL3N, but when i try to clear with MR11, its not showing any list.

2, one more issue, there is an huge difference in GR/IR account when compared with PO. , 1 200 000 DKK Goods receipt. 1 000 000 DKK Invoiced 846 756,88 DKK. But the GR/IR account shows huge amount (17526098.80DKK) in FBL3N with respect to specific PO. Please let me know the expected cause of this difference.
