Hello,
Make sure the valuation variant and costing version of the automatic cost estimate correspond with those of the manual cost estimate.You can check the valuation variant of the corresponding costing variant in T-code OKKN.
Make sure the quantity structure date (in the tab 'dates') of the automatic cost estimate in the T-code CK11N should be within the validity range (in the tab "dates') of the manual cost estimate in the T-code CK74N.
Set the additive costs of the corresponding costing variant as 'include additive costs' with stock transfer in the T-code OKKN.
Best Regards,
R.Brahmankar
