Dear Jyosh
Please try to use Additive cost through CK74 in your case for external services. Don't forget to tick additive cost button in your Costing Variant and Valualtion Variant, other wise it will not pickup additive cost. It will come in Standard cost of material.or your help below are the links on additive cost :

However, If you enter any additive costs in CK11N, It is done because you cant estimate additive cost through Qty Structure. But, the actual costs comes in order t through Material issues/Activity Confirmations. hence, the additive costs does not apply here. This is standard behavior of SAP, and I think we cant help it.
