Inventory procedure in 3PL

hi!

i searched in many topics but i cannot find proper answer. My question is how to implement inventory count, post, etc on locations which are linked to 3PL?

so basically stock situation is reported from 3PL right? And then we create all necesesaarry steps to do the inventory. But we cannot do inventory using standard FM for MI01 (BAPI_MATPHYSINV_CREATE_MULT) because we get error

so in which way then we can do the inventory procedure?

thanks for all answers and suggestions!
