Computation of Amount in LC (BSX and GBB) during MIGO

Hi Expert,

I would like to undertsand how is the amount in LC (for BSX and GBB of the accounting document) was computed during MIGO.

the entrries in my accounting document are the following:

TRS Amount in LC LCurr Quantity Unit of Measure
BSX 130,424.89- INR 5,330 EA
GBB 130,424.88 INR 5,330 EA
PRD 0.01 INR 5,330 EA

Based on my initial checking, the amount for BSX was computed by the standard price of the material*qunatity.

The standard price of the affected material was actualy 24.4699606. I just wanted to know how the amount in GBB was computed which cause of posting to a PRD account.

Thanks in advance.
