How to change std set up to get a stand alone APO 4.1 without R/3 linkage.

Question

Hello,
I have been looking for documentation/advise regarding the severing of the linkage of an APO system from and existing R/3 system so that it becomes a stand alone system.
Let me explain.
We have recently been bought out by a larger global company who have their own SAP system and are currently incorporating our system into it (DP/SNP & PPDS).
However the global company sees that the our Demand Planning Statistical Forecasting functionality is a local process as they do not use it, so it will not be taken within the global system.
This would mean that we would loose the statistical forecasting functionality, but we would like to keep it as it is fit for purpose and gives very good results.
What is being proposed is that the current APO system linkage be severed from R/3 as the execution will no longer be taking place as SNP an PPDS will be in the new system.
Then we want to set up the remaining APO system as a stand alone client just for Stat F/casting with no linkage with R/3, but linkage for the correct date with interfaces only from non R/3 systems.
From what documentation i have seen so far, it can be done. we just want to know what would be the best procedure to do this and what are the likely problems we will encounter.
Can anyone assist with this.

Answer 1

Nathan, you could get your basis group to break the link between your SCM system and R/3 through deleting rfc connections in SM59.
Of course you'll have to delete integration models on the R/3 side to stop data from being sent to your old APO system. It will cause an outbound queue once the connection is broken.
On the APO side delete you publication settings in SPRO to stop various txn elements from being sent out to the now disconnected R/3 system.
Cleaning up txn data would keep the system neat. Various ways that you can do this.
If all you are using is DP you can set the deletion flag on the product master once all of the txn data is gone and delete materials if you want to stop any processes other than DP being carried out.
Good luck,
