Hi Guru's,
just a 'simple' question about gATP and ALE:
when using gATP in an ALE scenario, is there anything to consider when having mixed orders ?
ERP system 1, sending system
having some items checked through gATP during order creation and some items having item category BANC with no ATP at all)
ERP system 2 , receiving system
all items go through gATP, result:
- the ERP-1 gATP items find the confirmation (by posguid)
- the ERP-1 BANC items call gATP but never get a confirmation
Any ideas how we can get a confirmation for the BANC items as well ?
Thanks.

Hi,
gATP via ALE, with 2 ERP systems...
- Is that possible ?
- If yes, is it a synchrone process ? ( network performance could be an issue ? )
Thanks,
Rolf

Hello,
yes it is technically possible (we do it). There are however some things to consider.
Technically
- during order creation in ERP-1 an ATP check is done using RBA to check on different locations
- quantity is reserved by creating TQA
- the identifier for the TQA (posguid) is included in the IDOC and send to ERP-2
- the sales order being created in ERP-2 uses the posguid to catch the existing TQA
The scenario however can become really complex when using allocation for example.

Thanks for so quick answer !
- What is RBA and TQA ?
We plan to do all the sales from ERP1 ( HANA SAP system with this gATP plugin ), but also check into ERP2 (non-HANA SAP system) if there are qty available.
The two systems are connected, but network-response-time is slow between the two systems.
- Do you replicate data from ERP2 to ERP1 via idoc's ? ( so no direct calls between the systems? )
Special idoc-type ?
Regards
Rolf
Hi Rolf
RBA is Rule-based Availability check feature provided in gATP. TQA is temporary quantity assignment which is created when you are in the process of creating an order so that the quantity is not assigned to other order getting created in parallel and there are no inconsistent confirmations.
Can you clarify on your requirement? Do you have plant A in ERP1 and plant B in ERP2 systems and do you want to first check if plant A can fulfill the requirement and then plant B? In this case it is very much possible to integrate ERP1 and ERP2 to a single APO gATP system and by using RBA you can achieve this.

YES !
As you describe !
We plan to activate the add-on to SAP ERP in our SAP ERP HANA box, where we have 3 Plant's. (Same Warehouse)
In additional, we have an "older SAP" ERP system in another country, with one Plant.
I have the Global ATP book from SAP, but everything is based on the APO solution.
Do you think the add-on will function in the same way ?
Best Regards
Rolf
Hi Rolf
What is the business process after you confirm the order from the older SAP plant B in case of no stock at plant A in your new ERP HANA? My obvious assumption is that you will first transfer this product from B to A and then deliver it from plant A? In this case you can use standard RBA feature to create a stock transfer from B to A.
You will have to use ALE to transfer this order information to another ERP system. I am not an expert in ALE so I am unable to provide more technical details on this but this is definitely feasible as we have implemented it where I work.
Hope this helps.

Hi,
There are many issues to consider regarding 2 ERP systems, and perhaps the most difficult one is "Global material numbers".
ERP1 has a material called A123, and same product is called B123 in the ERP2-system, so obvious today there are no integration between the 2 systems.
Can this mapping of material No's be solved ? ( Userexit and a Z-table with mapping ? )
Regards
Rolf
Hi
It is not recommended to have two different material numbers in this case. It will neither be user friendly nor be feasible to implement any of the gATP functionalities (or for that matter any other functionalities). Please have external number range for your materials.
In case of more questions, please create a separate thread and post in a relevant section where experts from that area can answer your queries.
Best Regards,
Parth Soneji
