thanks for that,

i tried this, COST field is showing the cost user enter manually, its not showing the BOM cost

You try this ? Click the compute from BOM button near the cost field in product form

yes;

Scenarios; i have hundreds of products, we have product standard cost and BOM cost

standard cost; we enter manually which is different from BOM cost

Purpose;

is to find the variance in Standard cost and BOM cost

to do that, i want to export, products standard cost and BOM cost into CSV
