Alternative Resource in CTP
Hi SAP Experts,
My current customer wants to use CTP to give a feasible date for Sales Order Schedule Items when entering the sales order. Is it possible to consider alternative resources (by using alternative sequences or resource classification) when entering the sales order? So the system would propose a shorter availability date in case preferred resource is fully loaded but alternative have some unused capacity.
Thanks and Regards

Hi Andre
You can obtain good planning results with finite scheduling on a time-continuous basis when it is used with block planning . This is always the case when the capacity requirements of the setup activities make up a large part of the total capacity requirements.
The following prerequisites must be met:
You are using a strategy profile with settings for time-continuous CTP .
The plan (PPM or PDS) contains only one resource to be finitely planned.
The blocks are defined on the resource. The planned orders created by CTP are scheduled in a suitable block with free capacity. The capacity requirements can be taken into account for sequence-dependent setup activities. The CTP check finds the correct dates in predefined setup cycles.

Alternative resources in production order - primary resource selected
Good evening,
I have a following problem, for which I have not found a solution:
we are using alternative modes in PPMs for reassigning orders to alternative resources and creating an order sequence for each resource in the Detailed Scheduling Planning Board (DSPB) in APO. However, when I convert a planned order to production order, this order is assigned to a primary resource again. Can I avoid this behaviour?
Thanks and best regards,
JevgeniThanks Thukral,
I also thought about that. Unfortunately, the prod order gets assigned to primary resource anyway. I've heard, when planned order is converted to prod order and sent to R/3, it reads PP data in R/3 and there in a routing, it calls up a primary resource. In addition, prod order does not contain alternative sequences any more and cannot be rescheduled to another resource.
I wonder, if this system behaviour can be changed or just accepted. But how is it than possible to to execute the sequences of orders created in the DSPB? It seems, manufacturing cannot use this sequence for execution, as all prod orders will be allocated to primary resource. -
Hi,
I would want to know if it is possible (and as to do this) to change in the process order (cor1, cor2), without having to use a different production version, a resource with an alternative previously defined in the master data of the same resource.
I apologize me for my English
Thanks
GiuHi Giuseppe Caselli,
Use Classification. Create a Class for the Work Center, ex. ALTERNATE, then assign this to your Resource's Classification.
Ex. WC1, WC2, WC3 = ALTERNATE (Classification)
Assign Selection Class in the Master Recipe as well (The Operation where you are using WC1)
Now, when you create process order, you can select alternative resources for WC1, and only WC2 and WC3 are available due to grouping through Classification.
Hope this helps. THanks! -
Alternative resources and alternative modes with CTM
Hi everybody,
we are trying to figure out, whether CTM supports alternative resources and alternative modes.
Does anyone know if it is possible or has even implmented the functionality?
Thank you in advance for your help.
Best regards
MitchHi Mitch,
It depends on what CTM profile you are using. 1) Bucket based or 2) Time continuous.
1) Bucket based : You will have to use SNP PDS and SNP PDS do not support alternative modes.
Alternative resources are not supported at all in SNP.
As an alternative, You can use the BAdi /SAPAPO/CURTO_SNP with CIF_IMPORT parameter to create multiple PDSes in case there is alternative resource in routing/recipe.
2) TIme continuous: You will use CTM PDS.
PPDS PDS supports alternative resources. I am entirely not sure about CTM PDS.
I will check out, if I can find out.
Which CTM profile you are using? -
How to create Alternative resources with constraints?
Dear Gurus,
i have an scenario where i have more than one resource giving same product as output having different capacities.
This resources capacity are utilised by more than one product and each reource has it own priority to a particular product.
example:
i have 4 products viz, A,B,C,D
and resources viz, RA, RB,RC,RD. the capacity is in nos of items per day.
lets say Resource capacities are
RA=150 nos ( can produce A,B,D)-priority to A than to B than D
RB=200 nos ( can produce A,D)-priority to D than A
RC=100 nos (can produce C, D)- priority is given to C, remaining cpacity can be used by product D)
RD=200 nos (can produce B,C,D)-pririty to B than D than C
how can i crate this scenario in APO..
regards
KiranHi Kiran,
First of all you need to classify the resources RA, RB, RC and RD suitably so that when you CIF production versions (for the products) from ERP to APO, in the PPM appropriate alternate resources are created under modes.
Then in each PPM you need to assign the priority for the resource (other way round from what you mentioned as your business requirement).
So in the PPM for Product A the primary resource/mode would be RA but then alternate modes RB (suitable lower priority).
Likewise in PPM for product B the primary resource would be RB and RD is alternate mode with lower priority.
For Product C PPM - primary resource is RC with alternate resource RD having lower priority.
For Product D it becomes complex - primary resource is RD but then probaly RC >> RB >> RA would be the order for alternate mode priority.
Hope this helps.

Produce one planned order in more resources at same time
Dear Experts,
My client uses PP-PI and he has a requirement for a line that he has 4 resources to do the same operation. We are using a class 019 to plan the resources as alternative resources, but he also wants in some cases to produce the same process order in more than one resource at the same time.
How can I produce the same process order in more resources and do not split the order?
Thanks in antecipate
Thiago CyrilloIn the case of some special case, you could add some operation to the process order , assign it to the different resource and link the phases of these operations as parallel. You should also enter the operation quantity, this is the way that splitting takes place.

Massive change orders to Alterntive Resources in planned Orders
Hi SAP Experts,
We would like to change a lot of orders from one resource to an alternative resource in the DS planning board. We can only do this order by order but in such case we already know that for a set of orders we have the same alternative resource so I would be easier to just select a lot of resources to move from one resource to another resource.
Thanks and BR
MauricioHi,
If you know the orders/operations, which are to be moved to alternative resource, you can select them using CTRL+click on those operations. Then by drag and drop, you can shift them to the alternative resource. While drag and drop also, you have to keep the CTRL key pressed.
Hope this will help you.

Hi
I have one PPM with one activity and 2 alternative modes.(I have classified the reources in ECC)
The problem occurs when converting the planned order into process order. The order in APO misses the activities, although in ECC the order has the operation and fase.
I only have this problem with alternative modes
ThanksHi fernando,
1) Press "consistency check" button inside the ppm and check any errors do you
observe.
If yes, you need to correct the PPM before planning run.
2) Check bom and routing whether maintained with alternative resource
correctly with the classification
3) Check classification view of material master defined correctly.

Dump "Message X" when converting plan.order in APO (Operation classified)
Hello,
We are using master recipes. One operation is classified with work center class type 019 assigned. Operation is classified with two values so I get two alternative modes in APO PDS.
I can drag and drop between alternative modes in the Planning Board, and then save so I can see the mode change also in the order processing view for example.
However when I am triggering the conversion of planned to process in APO then order is never converted. An error queue appears in the qRFC inbound monitor in ERP stating that a short dump has occurred
Short dump "MESSAGE TYPE X" Information on where terminated
Termination occurred in the ABAP program "SAPMSSY0" - in "%_ORDER_FORM_LEVEL". The main program was "SAPMSSY1 ".
Thanks in advance
CarlosHello Carlos,
Have you updated alternative resources with the values in the user fields of the operation. ?
Also assign the work center class for the operation (same class which you have assigned for the work centers)
Best Regards,

Hi,
I have a basic question with regard to PPM.I have 2 workcenters A and B in which i can process the same product. Following are the possibilities in R/3 and APO.
1. I have defined workcenter B as alternative to A using classification system. I have defined the Routing in R/3 with workcenter A and transferred to this APO. Now i have PPM for this material with two modes A and B.
2. I defined the Routing with Workcenter A and maintained alternative sequence with work center B.When i transfer this Routing to APO, system creates a PPM with alternative modes A and B.
3. I have defined Routing with two group counters with different base quantities. one group counter with with workcenter A and another group counter with workcenter B . When i transfer these (these are two production versions), it creates 2 PPMs in APO.
What is the difference between 3 and above(1&2).
When we run the MRP Heuristics in PPDS with finite planning,system will check the alternative resources also,if the primary resouce is not having capacity. Similarly the system should check alternative PPM2(resource B) also if PPM1 (Resource A)has no capacity.
I believe we define 3rd case if the processing of the base qty ( and if lot sizes also different) is different in different work centers.That is 200,000Kgs qty can me machined in 24 hours in Workcenter A and 350,000Kgs qty can be processed in work center B. Is it correct?
Please comment.
Thanks
AktarHi,
In step 1 and 2 you created alternative resource. And in step 3 you created alternate routing / recipe.
If you are using both SNP and PPDS then creating alternate resource helps as PPDS can change the resource after SNP in PPDS optimizer run.
But if you use alternate recipe then you wont be able to change resource in PPDS as SNP will decide which recipe to choose and subsequently PPDS will follow it.

Ignore PPM Mode Linkage in Planning Board
Hello experts,
I have a a burning question here..
I'm working in a project whose using PPDS PPM with more than one activities, and multiple modes (for alternative resources). In the Activity Relationship, we define Mode Linkage as '3', so whenever we schedule an operation in Planning Board, the predecessor operation will be scheduled according to the mode relationship in PPM.
There is a requirement to break the 1-1 mode relationship for exceptional planning during short term period. Without changing the Mode Linkage, can we break the relationship in Planning Board using a specific PP/DS strategy?
*Hope my question is clear enough
Thanks
YudhiaHi Santosh,
Thanks for the reply.
When I changed the Order Int-Rel to Do Not Consider, I couldnt move any order (inlcuding dep.orders) to alternative resource.
So now, I'm using Order-Int.Rel = Always Consider and I have the flexibility to move it to alternative resource.
But the problem is that I think it always read the Mode Linkage in PPM. Whenever I move the dependant order to it's alternative resource, the parent order will also moved accoring to mode relationship.
Whereas the requirement it to break the relationship for exceptional case.

SNP - Capacity Leveling question
Hi All:
I am trying to do Capacity leveling in one resource and for one material.
After CIFing the material, resource, location and BOM (PDS), I entered some forecast for the specific material in DP and released it to SNP.
Then I ran the product heuristics and when I looked at the planning book 9ASNP94 and Data View SNP94 I noticed that the capacity utilization where more than 100 % in some periods.
Next I executed the 'Capacity leveling button'. and entered the following parameters and executed.
Combined Scheduling
100 % max util
Product priority
Ascending
Heuristics Method
All Relevant Resources
In the Log checked all the three options
The log comes out as follows:
Green status on Resource and Parameters
Yellow status and 'Resource xxxx not used in any PPM/PDS'
Red status Resource utilization
I checked the PDS for the resource xxxx and i found it to be there.
When I go back to the Capacity view the leveling has not happened.
What am I doing wrong? Pl. help.
Thanks
NarayananHi Narayanan,
I think there should be any issue. I hope You selected the data view snp94(2), and loaded your resource in the planning book. then You executed the 'Capacity leveling button' in the planning Book, Right? Try without checking the 'consider alternative resource' check box, and dont give any priority in your capacity levelling profile.
Thanks,

We are exploring Capacity leveling with optimization method. from the SAP help documentation, it is understood that Optimizer generates the cost based on the procurement priority maintained in the cost.
Excerpt from SAP Help:
"Optimization-Based Capacity Leveling
The system considers the alternative resources according to the
procurement priority of the PPMs or PDS. The system automatically
converts this priority into costs, so that PPMs or PDS with higher
priorities are considered first. The costs of the original resource are
defined by the system as lower than the costs of the alternative
resources, so that this resource always has the highest priority for
the
optimizer and so that the system uses it completely first."
Base on the info, we setup the PPM master data.In my scenario, we have a product that can be produced on 5 different work centers so i created 5 PPM and assigned different proc priority codes like 1, 5, 10, 15, 20. PPM with priority code 1 is primary resource and rest are alternative.
Expectation was that when CL-OPT is run, Optimizer would generate costs as per the priority codes where 1 is higher priority so lowest cost and rest would be incremental higher cost.Which would drive the leveling of the resource load.
But the fact is optimizer created lower cost 250 for priority 1 PPM and 500 for rest of the PPMs.
I would like to understand, is this the correct behavior as it does not align with the SAP help document and we are not able to get appropriate results.

Harshil DesaiIf you have ERTMS as the sorting criterion, then it is the create date. Otherwise it is purely random. Dont bet on alphabetical as I have sometimes observed to the contrary.

APO SNP capacity levelling heuristic
I am using APO V5 SNP.
I have a question about SNP capacity levelling heuristic.
As I understand it, the heuristic works on a resource by resource basis and will aim to capacity level across time buckets.
But suppose I have a product which has two different sources of supply (PDS/PPM) using different resources X and Y.
Suppose the capacity using resource X is overloaded for week n, but resource Y is not overloaded.
Can the levelling heuristic be used to move capacity from resource X to resource Y for week n, or would this have to be done manually via changing the PDS/PPM?
Thanks,
Bob Austin, Atos OriginBob,
You can move the load from X to Y if Y is an alternative resource to X. This can be accomplished by going to the capacity levelling button and then in the options check the box for 'Consider Alternate Resources'. After that you can mention muliple alternate resources also to be considered.
Hope this helps.

1. I would like to know the major differences between PP discrete and PP for process industries.
2. When and why do we implement PPPIinstead of PP?
waiting for valuable answers!
thanks in advance
AritraHi Anitra,
I'd like to add some more things:
1) PI-Sheet:
By using PI sheets PP-PI offers all the answers to regulatory requirements like
- Digital signatures
- Audit trail
- Validated input fields (e.g. if value is out of tolerance a deviation will be created that is also displayed later on in the deviation analysis in the EBR)
- Event-based instructions (e.g. locking/unlocking instructions triggered by formula functions) improve the quality of the process by guiding the user.
- Use of EBR (electronic batch record): all batch relevant data, including the PI sheet(s) are collected there and can be approved.
- OPC functionality: Standard instructions to us SAP's OPC interface
2) Resource networks
Hardwirded resource connections can be modeled by that (e.g. 1 reactor beeing connected to 3 alternate tanks which are leading to other resources)
3) Selection of alternative resources following specific requirements (e.g. selection contains only resources that fulfil a certein specification like corrosive-resistant)
4) Approval processes for recipes (routing + BOM)
5) Phase relationships allowing also parallel and sequential tracks in the routing
6) PI-PCS interface
Sending process parameters to an external system (PLC, weighing system,...) instead to a PI sheet
