In SAP S/4HANA Transportation Management for Logistics Service Providers (LSPs), instruction sets provide standardized instructions for transportation processes. According to the SAP documentation, instruction sets can be assigned to:

Stage type (A): Instruction sets are linked to stage types to define specific instructions for each stage of a forwarding order, such as loading or customs handling.

Forwarding order type (C): Instruction sets are assigned to forwarding order types to provide default instructions for the entire order, ensuring consistency in LSP scenarios.

The other options are incorrect:

Movement type (B)is used for defining stage sequences or transportation modes but does not support instruction set assignments.

Freight order type (D)is used for execution documents and typically does not include instruction sets, which are more relevant to forwarding orders in LSP scenarios.
