Hi @Marcin Szczurek,
I am not sure I got your question fully also the flow that Customer execute here exactly with the description above.
As I remember the process in App8 was, when you detach a work order from a project which has Purchase requisition in Planned date, then preposting's also will remove from the Requisition. I.e. Originally the PR also have this project connection but when you disconnect from the work order then connection also get removes automatically from PRs. After detaching, there is no connection to the previous activity for those PRs at all.
Next, when you connect the work order to another activity then existing PRs will also be connected to the new project activity. There will not be any transfer of material to the previous activity unless we manually do in this instance.
However in app10 version the function is quite different. I.e. we could not detach a work order from a project activity unless all the lines from any connected PRs are removed or cancelled. I assume RnD has done this change in App10 due to some concerns in the flow, yet I am not able to identify what exactly the reason was.

Kasun
Thank you very much Kasun!
