Dear Mangalraj,
I have the same problem with Nattakarn.
I checked every information you noticed, but the problem still didn't solve.
Could you please help me check it again?
I ensure:
1. The priority 1 of my valuation variant in costing variant is "L".
2. I had created a Purchase Info Record in ME11 for sub-contracting category, and I maintained the price in the info record.
3. There is a BOM exists for this product.
But, there still a CK468 error. When I create a po from this info record, the error disappeared.
Best Regards,
