Incorrect units on G/L (F0911.GLU)

Hi,

We have order for non-stock item and units on the G/L are getting posted incorrectly.

Below are the details...

1. Order has non-stock item with primary UOM as PK, secondary UOM as LB and pricing UOM as TN.

2. Account sales a/c setup as M3. P41002 is setup with PK to M3 for the item.

After sales update GLU is updated with quantity in LB and GLUM is updated as M3.

Which UOM conversion is required on P41002 to get units converted to M3 on G/L?

Thanks,
