Integration Models and CCR simultaneously . .

[Former Member]

Dear All,

i have 2 questions :

1) Why cant we run two Integration model simultaneously ???

and

2) Why cant we run CCR jobs in parallel with planning run ???

Please let me know your observations and opnions.

Regards,

Hi Prasasd,

There is nothing like system will carry out planning run for externally procured items first and then in-house production items. System will carry out planning run as per the BoM components and Low level codes defined in the system. The system will starts planning from the low level code components.

If the low level item is ext proured, it puts up purchase requisitions and if it is inhouse, it puts up planned orders. Hence, during both cases, it is not advisable to run CCR simulataneously. Also, there is an intermediate step like updation of planning results which you have not mentioned here. ie Once the planning run gets completed, it gets updated the results into its corresponding systems.

ie Planned orders and purchase requisitions gets transferred between the systems via queues. If there is any queues struck, then updation will not happen. Hence it is necessary to clear the queues before start of CCR run.

Hence the ideal process is to clear the queues first, run the CCR for getting data same in both the systems and then carry out the planning run.

Hope it is clear now. Please confirm.

Hey Thanks Sai and Senthil for your answers. . .

now its better clear to me . . . .

Thanks once again. . .

Hi Prasad,

Below are the answers for your queries.

1) Why cant we run two Integration model simultaneously ???

Integration models are the building blocks of both master data and transactional data for APO. It has to be contructed in APO in a sequence or in a order so that the updation of data can be performed sequentially. Each data will look into the update of other data. For example, we need to run integration model for location first and then location-product. The first run of location will create integration model for location in APO and then when we run subsequently the location-product, the combination will be referred in APO. If we run both location and location-product together, if location-product tries to update the APO system first(tables) before location data, then it will throw out error and cancel the model run. Hence, it is advisable to run the models one by one in a sequence.

2) Why can't we run CCR jobs in parallel with planning run?

CCR runs will compare the transactional data between both R/3 and APO and display the results. Planning run will perform the planning based on the selection conditions and it takes data from both R/3 and APO. The planning results will be transferred from APO to R/3 based on our customisation settings. During the time, when transfer of results happening, if paralley, comparison of both system data happens via CCR job, it will not give correct data or end up with errors or tries to cancel the job.

Hope this clarifies your question.

Please confirm whether you are clarified?

Hey Thanks Senthil for your answers. Yes this has cleared many a my doubts.

But please can you also explain,

" if while planning run is underway for the externally procured products and it has just completed all its planning for the Inhouse Products, and if start with a CCR for the inhouse ones, will the system throw an error and cancel the reconciliation job ? "

If you have two different jobs for Purchase Reqs and Planned orders then CCR will show the errors for Planned orders as the In house planning has already completed.

Also in case of Purchase reqs where the planning is still in process, the CCR job will not terminate but it will not show any inconsistencies of the current planning run.

1) Why cant we run two Integration model simultaneously ???

Assuming that you are refering to two IMs of different Masterdata/Transactioanl data, we need to maintain certain sequence while CIFffingf the data. Like master data has to be CIFfed before transactional data. Even CIFfing Masterdata you need to maintain certain sequence like Customizing ATP, Locations, Materials, work centers, PPM/PDS, Purchase Info Recerods...otherwise queues will be blocked with errors.

2) Why cant we run CCR jobs in parallel with planning run ???

CCR jobs are run to make both APO and ECC systems in sync. There will be data inconsistency in both the systems when there is data transfer. Data transfer like Planned orders/Purchase Reqs/PO etc will be done only after their creation in either APO or ECC and this can be done only after the Planning run. Let me expalin this with an example:

You are simultaneously running CCR and SNP Heuristics for a Product P1 at location L1. Say CCR job finishes before the Heuristics job..you observed that there were some inconsistencies and you have corrected them. Now Huristics job completed and it created a purchase requisition but because of some reasons it got stuck in the queues. Now there is some inconsistency in both the systems. you see Pur Req in APO but not in R/3. But you can correct this only if you run a CCR report. So, there is not much benefit in running the CCR report simultaneously with Planning run
