GR/IR Clearing issue

Hello All,

We need to understand the process to do the automatic GR/IR clearing (F.13 ) for below scenarios:

Case-1 :

GR - 100 Qty - GR/IR account value = 100 USD

Inv- 99.98 qty - GR/IR account value = 99.98 USD

Case-02:

GR - 100 Qty - GR/IR account value = 100 USD ( Doc currency ) / 5000 INR (Local currency )

Inv- 100 qty - GR/IR account value = 100 USD (Docl currency) / 5009 INR ( Local currency )

we need clear GR/IR for the above cases before this month end closing.

can you please check and suggest me how to handle this situation.

Regards

Ram
