External Interfaces & Licensing

[former_member199632]

Hi,

I would like to clarify some points regarding connecting/ linking external applications with SAP

Environment -------

SAP ECC 6.0 (EHP 0) with Oracle 12C DB

Netweaver 7.0

------------------------

Aside from SAP system, We have some internally developed systems. No PI integrations / No PI Licenses yet

1. I just want to know, is it possible to link those systems with SAP ? (Query data out from SAP DB & write back to SAP DB)

2. Is it possible to Query data & Write back to SAP system via RFC connections? is it a must to have valid license for this / can we proceed dame with ECC license?

3. What is PO (Process Orchestration in SAP)

Looking forward for the clarifications on this.

Regards,

Zerandib

Hello ushan.pathiratne

Ad 1. Yes, it is technically possible to read SAP data directly from DB and write it back. But you should never ever write data directly to SAP DB as it is a sure recipe for data inconsistency. SAP data model is very complex and relations between tables e.g. foreign keys are not modelled on DB level but on the application level. You should use SAP provided interfaces instead. For the same reason you should use interfaces to read data from SAP. To put it shortly, it is technically possible but not recommended.

Ad 2. Yes, you can use RFC connections to read/write SAP data. All your integration scenarios have to be covered by some SAP license or you risk indirect use license terms violation. You may think about digital access license or provide each user of an external application with SAP license. Think of the integration like this - each user writing data to SAP is using SAP, even if they are using SAP indirectly from an external, integrated application.

Ad 3. See:

in addition to point 1. - in case you use a SAP Oracle OEM license is is not allowed read or wirte data directly from/to the DB. The only exception to my knowledge are DB management tools. But business data is a big No No - reading AND writing.

pamai That is spot on comment of yours.

To summarize direct DB access - it is possible technically, license terms forbid it, data model makes it very hard to implement. So it is a no go.
