There is no special procurement type 40 available as default for stock transfer from plant to plant.
SAP S/4HANA Cloud
In S/4HANA Cloud, currently there is only one plant activated per country by default.
Thus if delivering a special procurement type for stock transfer from plant to plant, it is impossible to give a source plant in content since it will cause activation error.
Although the special procurement type 40 is not delivered by default, it is supported by standard.
Go to SSCUI: 101111 (Define Special Procurement Type) to create a new special procurement type like 40 for stock transfer from plant to plant.
