How Initial CIF for a new plant without any negative affected to productive system?

[leventoturak]

Hello everyone
i need your help for my next CIF(Core interface) enhancement on productive system.
I have created a seperat integration model for each masterdata (materials, vendors, reservations, stocks, purchase orders, sales orders,
purchase info records etc. ), which are running every night in a process chain.
Until now everything runs perfectly.
I have created a new plant and completed all migrations for this plant in ERP System.
Now I plan a initial CIF for this new plant in order to transfer all master data of this new plant from ERP to APO.
I don't want to add immediately the new plant in the existing integration models with another 10 plants and
let it activate by process chain,
because it would be take so long due to new plant in next business hours and the productive system would be affected
negatively.
For this reason i want to run a initial CIF run for the new plant at the weekend except for business hours.
After the initial CIF run for new plant, i will add the new plant in the all variants into the process chains, so that
the delta CIF will run with other plants next day automatically.
Firstly, i plan to start with the materials. The integration model for the materials is already created (the report RIMODGEN)
and activated, it runs automatically every night within the process chain (the report RIMODAC2).

This integration model for the materials contains currently 10 plants.
How should i proceed with my CIF run for a new plant, so that the productive system won't be affected (negatively)?
I would call the transaction CFM1 in ERP and choose the program variant for materials, then delete all existing plants from the plant selection and
add only the new plant there. Because I only want to start the initial CIF for the new plant.
Afterwards, I will click F8 (run the transaction) to create a new integration model.
Now I will have a new integration model with the same name for the materials with only the new plant.
At this moment the integration model with the same name for the materials with 10 plants will be still active.
I have not activated the integration model yet which contains the new plant.
If i start the initial CIF by transaction CFM9 and enter the name of the integration model, which integration model would be run? (active integration model with 10 plants or
the integration model with the new plant which i have new created)
or recommend you create a new material integration model with new name for the new plant (CFM1) and start this
integration model by transaction CFM9?

Thanks in Advance

what do you mean by below?

because it would be take so long due to new plant in next business hours and the productive system would be affected

Have you not tested the same in quality environment? Is it taking time in quality if you put new plant in your exisitng IM model. I don't expect any performance issue to CIF new plant to APO.

Its not recommended to have one object in 2IMs. Just test the same in quality box by adding the same in your integration model.
