Split Production Order Issue

Hello all,

Can someone help me with an issue I'm having with the split production order functionality in SAP?

I'm trying to split a production order, but the actual costs of previous operations are not being transferred to the child order; only the costs related to goods issue are being transferred. I've already checked the "Split Actual Costs" checkbox in transaction OPL8 and performed operation confirmation for the previous operations. However, the costs still aren't transferring as expected.

All cost configurations are properly maintained for operations (Work Centers). Is there something I'm missing or an additional configuration that needs to be checked? Any guidance or suggestions would be greatly appreciated.

Thank you!
