SAP IDoc Technology

SAP IDoc technology

SAP IDoc technology is used in ALE, EDI, and third-party systems.

Integration scenarios.

For some of my readers, this may be a journey back in time, but for some

new developers, I hope to give you the tools you need to understand

and demystify the IDoc concept. Also … for you old dogs, see it as

Take corrective action and step in with comments and suggestions. Let us begin !.

What is IDocs?

Evidence You may have heard the term IDoc many times. This blog will help you

understand what an IDoc is and what it is used for.

Let’s look at some key facts about IDocs.

– The term IDoc means intermediate document. It’s just a fact

Container for exchanging information between two processes that use

You can understand the semantics of the data.

– An IDoc is generated as a result of the execution of an outgoing ALE or EDI process.

whereas with an incoming ALE or EDI process, an IDoc is used as input for

creating an application object in SAP, e. B. a sell order or a buy order.

IDocs in the SAP system is stored in database tables. We can use

process, edit, and process. When an IDoc is generated in

The IDoc interface

How are IDocs used? What is EDI? ENGLISH BEER? Here I could reveal my age….

but the IDoc interface has existed since version 2.2 when IDocs existed

originally used in the EDI process. So this is a proven and scalable technology

used in a variety of interface requirements.

EDI Integration (Electronic Data Interchange)

EDI is the electronic exchange of business documents between retailers.

Partner in a common industry-standard format such as ANSI X12 or

MEDIFAST. Several applications (purchasing, sales, or shipping) are in SAP

enabled for EDI. An application to use EDI? First, create an app

Document, as an order. Then the EDI interface layer becomes

the requisition document (the purchase order) in an IDoc that

streams an EDI or PI subsystem with an EDI plug-in. The EDI

Middleware translates the IDoc into an industry-standard format and then

You to a business partner over a network.

ALE integration (activation of application links)

ALE enables data exchange between two SAP systems. This is what SAP makes possible

Business processes and applications have to be distributed across several SAPs.

Systems. ALE ensures integration into a distributed SAP environment. The IDoc

acts as a data container. SAP started ALE as an initiative to support a started

Distributed but the integrated environment. ALE enables efficient and reliably

Communication between distributed processes through physically separated

SAP systems to achieve a distributed but integrated logical SAP system.

Since the ALE architecture is system-independent, this is the case

that enabled SAP to use this technology for SAP on non-SAP systems. these

were huge in ALE’s early years, which resulted in it being called a
