Hi!
We use IS Mill solution on R/3 side, variant configuration, PDS and are considering of using CDP for the following.
There is a configured sales order position, some characteristics of which are evaluated and propagated to an intermediate conversion (g.e. WIDTH = 1000-1100 mm). There are some stocks in batches for the conversion. Batch classification characteristics are match to configuration characteristics (e.g. WIDTH, Batch1 - 1020, Batch2 - 1090, Batch3 - 1150 mm and Batch4 - 1020-1080mm).
Can CDP consider Batch1, Batch2 and Batch4 as receipts for the depended demand for the conversion?
If no, is any workaround to cope with such a requirement?
Thanks.
The answer for your queary is no.
if you see the help document in apo
Integration via APO Core Interface (CIF)
then
Integration of Master Data and Transaction Data
then
Integration of Batches
Characteristics-Dependent Planning (CDP) and the characteristics-based product availability check cannot process batch valuations that contain multiple values or intervals.
you can do one thing make another characterstics which takes the characterstics width1, (mark this also apo relevent "Z" ) then enter the higher value say 1100 in sales order , then at the time of batch creation some one needs to check the value and make it to the round of say 1100, then it will consider during cdp planning.
this is only you can make arangement .
hope it helps you.

Ok.
Let's assume we will use only single value in batch classification. The characteristic will allow intervals, but we will always use concrete value.
The task is to consider characteristics of batch stocks during planning process to avoid of creating unnecessary planned orders. If sales order position requires some interval of characteristic value on a intermediate conversion, the system first of all must use appropriate batch (if batch characteristic value fall into interval, required by dependent requirement for the conversion) to cover it. Secondly it must create the planned order for the conversion with required interval in its configuration.
According to SAP help:
Characteristic value assignments for the configuration and the batch classification only use single values. You can only use multiple-value characteristics for characteristic requirements (for example, for block basis definitions, rules in the PPM plan, or characteristic requirements from batch selection criteria). You can then specify multiple values for characteristic requirements for characteristics with character format. For numeric characteristics, you can also specify an interval in addition to multiple values.
Does it mean that wishful scenario is impossible?
Your requirement can be covered in the Mill solution by using batch selection criteria for the the width characteristic. The batch determination procedure will create the characteristic requirements for the sales order item for example width from 1000 mm to 1100 mm. In APO you can see the characteristic requirements in the product view for the sales order item. If you use the PP/DS ATP check the system will find the batches and assign them. To activate PP/DS ATP you need to make the following settings in the ATP check instructions in customizing:
Maintain Check Instructions
Product Check: First Step
StartProduction: Production Directly
F1 help:
In the case of Direct Production, no ATP check is carried out; rather, an availability check, which runs according to the rules of the net requirements calculation, is carried out in PP/DS. Based on the result of the net requirements calculation, a decision is made in PP/DS as to whether receipt elements should be created.

I've just read a book "Characteristic Based Planning with mySAP SCMu2122" written by Jörg Thomas Dickersbach. According to the book:
With the CDP-configuration relevance the orders have valuations and requirements
which contain the values of the characteristics. The valuations
in APO are integrated with the configuration in R/3 or the batch classification
(for batches). The requirements in APO are integrated with the batch
selection criteria in R/3. Both the demand and the supply nodes (i.e. the
requirements and the receipts) of the locationproduct have valuations u2013 or
at least they should. The valuations describe the value of the object itself
while the requirements of a demand represent the conditions for a receipt
to be pegged. If no supply with the same valuation exists, supplies with
matching valuations according to the requirements of the demand node are
considered. Only if no satisfactory supply exists, no pegging takes place.
And:
For some business cases it is necessary to use requirements for the characteristic
values in the dependent demand (e.g. cables because the length is
modelled as a characteristic). Using the PPM it is possible to define requirements
for characteristic values. With APO 4.1 this is not possible
within the PDS. There is however a way to model requirements when
planning with the PDS as well by defining the requirements for the
planned order directly (instead of defining it in the PDS). For this purpose
the BAdI /SAPAPO/RRP_SRC_EXIT for the planned order creation has to be
used. The method RRP_USEX_PLORD_CREATE allows the definition and
assignment of the requirements.
If planning is performed with requirements, specific production planning
heuristics are required. The normal production planning heuristic
does not provide sufficient results.
It seems that using of requirements for the characteristic
values can solve my issue.
Can anybody tell what are the "specific production planning
heuristics" that required for planning with characteristics requirements?
And may be anybody give an example of using the method RRP_USEX_PLORD_CREATE for "definition and assignment of the requirements"? I've look at it and do not understand how to define characteristic requirements for the planned order's demands.
Thanks.

With the help of APO You can do the character based planning , that means if you run MRP in ECC system it consider only materrial code for net requirement calculation, while APO takes the characters for net requirements calculation.
The BADI you have mentioned are used for creating the planed order creation , and basicaly used for netting purpose( based on selection logic).
If still you have a doubt you can raise a OSS message for the same to get the exact reply from SAP.
Thanks.
Hi,
Following is extract of SAP Help page under topic Integration of batches. It is self explainatory.
>>>Characteristics-Dependent Planning (CDP) and the characteristics-based product availability check cannot process batch valuations that contain multiple values or intervals.
We have implemented one IS mill project where we have forced the user to specify single value in sale order
