sales interface from external systems

[Former Member]

hey,

Sales will be interfaced into SAP.

We will interface transactions from three separate external systems.

We could receive the same document number from each of the three systems. What makes a document unique in SAP? These documents could conceivably be for the same customer. Would that be a problem?

Please advise.

Thanks

Hi there,

When maintaining an external system, there will be 2kinds of transactions.

Inbound to SAP & Outbound to SAP.

In inbound, when a doc is created in an external system & comes to SAP, that particular doc usually comes in the form of an IDOC. The external doc num will be populated in one of the IDOC segment fields. The same external doc num will be populatedin one of the fields of the SAP document as a reference num. We usually use any field which is not used to populate this.

In outbound from SAP, the information is sent to external system also as IDOC. In tis case, we populate the SAP doc num in 1 of the segments of IDOC. The same value will be populated in on of the fields as an external reference num.

We define the segments & fields of an IDOC message type in t-code WE30.

If this doesnot clarifiy your question, pls eloborate your question.
