EWM Setup in embedded system S4 2022 FPS 02 seems faulty

Hello experts,

we are struggling with some missing synchronous goods movements posting. Could be that the system cannot read the data propperly  from control cycle because is dows not find the right entry due to missing warehouse number.

in lpk1 forward navigation with staging method 5-ewm the entered psastage screen is not showing up with filled warehouse number. this is causing a lot of neg. side effects. i adjusted the supply chain unit  connection to the business partners. from a former consultancy this entry seemed incorrect. but the correction was no sufficient. what can i checke else? problem is quite urgent due to productive impact.
