Structure of customer extension. If the customer extends an SAP basic structure, he must give a name to the structure of his extension. |
Required field if there is a customer extension; otherwise initial. |
rcvprt |
Partner type of the receiver; LS (logical system) for ALE. |
Optional field. See below. |
rcvprn |
Partner number of the receiver; the logical system for ALE. |

rcvpfc |
Partner function of the receiver; normally initial for ALE. |
Optional field. See below. |
When the receiving system has been determined from the distribution model, it can be written to field rcvprn. Field rcvprt must then be filled with LS (for logical system). If necessary, the partner function can be written to field rcvpfc. However, the partner function is not normally used in ALE. It is important that rcvprt and rcvprn are both either left empty or filled. If rcvprt and rcvprn are passed with their initial values, the receivers are determined entirely in the ALE layer.
