Reservation with Extended classic scenario

Question

Hi ;o)
I'm working at a costumer were we have extended classic scenario. We want to be able to make reservations in the backend if the item is on stock, and we have seen in a solution matrix from SAP that this should be possible.
The configuration for reservations should be done according to the guides - but no reservations is created when ordering a stock material.
I was searching on the developer network, and came across a topic, where it was stated that reservations could only be made with classic scenario (or using a BAdI where you switch the extended on and off depending on product category). Do any of you know if this is really a fact?
Thanks in advance

Hi
Read this first.
<u>You can use BBP_CREATE_RES_BACK BADI using Se18 Transaction.
This BADI You can find in SPRO -> Supplier Rel. Mngmt. -> SRM Server -> Business Add-Ins -> Follow-on document generation -> Reservation in Backend System</u>
<u>If you want to create reservation, you have first to switch from ECS to classic scenario through BBP_EXTLOCALPO_BADI then you have to implement BBP_TARGET_OBJTYPE badi to determine the criteria to create a reservation in your backend.</u>
<u>We need to maintian the customising setings in SPRO Transaction.
Define objects in Back end systems. Maintain the document type EC or ECPO for Purchase Orders and not for creating reservations. Maintain number ranges (RS) and align the same to R/3 or backend systems. In setting up the org plan in the PPOMA_BBP Transaction, the attribute for resevation - Attribute BWA should be maintained too, if reservations are to be created in the backend system.
Movement Type Accounting Object
201 Cost Center
221 WBS-Element
231 Sales Order
241 Asset
Example :
logicalsystemname\201</u>
<u><b>Maintain the following Settings in the IMG using SPRO Transaction.</b>
1.For internal Procurement > 1.Always Reservation for Material types Subjected to inv Mgmt
2.For External Procurement >1.Always purchase Requisition.
Note -> The plant that you use to create the shopping cart might not be extended to handle inventory management. Select a right plant which is extended to inventory management and you will see a reservation being created.</u>
Be aware that:
- with the classic scenario you can create PR, PO and/or Reservations in R/3, but there is no local purchasing document (except the SC), so all functions around the local PO will not be possible.
- with the extended classic scenario, you can only create PO in the backend, but a local PO exists in SRM.
Concerning GR, it is possible to make it in SRM for both scenario
Hope this will help.
Please reward suitable points, incase it suits your requirements.
