Rule Based distribution of leads
Hi
For maintaining the rules for rule- based distribution of leads, which business roles are relevant? Can we do it by using roles marketpro or salespro ?? Please guide.
Regards
Aakshi Suri
hi
can you plz explain your question elaborately
if you to use business role----
den used MARKETINGPRO bt before using the b.role convert into "z-transaction" den use it

Rule-based distribution for opportunities
Hello,
I've configured a rule for opportunity distribution in 'Rule Policies' in SAP CRM Web UI. The rule is shown as 'Active' and 'Released'. However, when I create an opportunity and select the distribution method as 'Rule-Based distribution', then the dropdown the field 'Rule' stays blank and I don't get any options to select a 'Rule'. Please provide your inputs on how the rule I created can be made available for an opportunity.
Regards,
Aditya MishraHi Aditya,
Have you configured a service profile and assigned your rule policy to it? You can set this up in:
SPRO --> E-mail Response Management System --> Service Manager --> Define Service Manager Profiles
1. Create a new service profile
2. Add in service ID DD_RE
3. Under property ID add in CONTEXT using value DD_OPPORTUNITY
4. Under property ID add in POLICY using the rule policy ID you created.
I hope this helps.

Rule based Lead distribution is not working.
Hi friends,
I have created Lead distribution rule for assigment of Leads to Sales representative using below condition :
If
Lead Main Partner Postal Code Contains "12001"
Then
Partner by ID ( Assign Business Partner ID = Will Smith(BP id)
Set Partner Function To = Sales Representative
Set Lead Status To = In Process
Execution behavior = Stop after execution if partner(s) found )
I am using standard service Mgr Profile for lead distribution, when i am executing standard report CRM_DD_BATCH by giving values Object Type, Transaction Type and Service Mgr Profile it does not work i.e. assignment not happens but in addition to this if i mention specific Lead no. into report field ID it works perfectly.
I dont understand what i m missing, please help me if anyone has come across the same scenario.
Thanks in Advance,
Dipesh.Hi Dipesh,
Have you ever fixed this issue? I have exactly similar problem...Appreciate if you can share the solution/root cause of this problem, if you found any. Thanks. -
Lead Assignment Rule Based on Industry and Zip Code
Can we set up a lead assingment rule based on multiple conditions?
For example, if Industry = Retail and
State = VA assign to Bob
State = MD assign to Jim
State = CA assign to Karen
Industry = Commercial and
State = NY assign to Lam
State = VA assign to John
State = CA assign to Karen.....Hi Bob,
In continuation to your reply, can we add more complexity to these rules like with industry and state, if i want to assign a lead based on to the tyoe of product and the revenue of the company.
e.g.
Industry - Retail
State - MA
Product - ABC & Revenue of company - $100M - assign it to Sales person 1
OR
Industry - Retail
State - MA
Product - ABC & Revenue of company - $1M - assign it to Sales person 2

Documentation about Rule-Based Account Assignment Distribution
Hello dear PSM Experts,
In our project (using ECC6), we want to split in a PO the FM account assignment between several lines, according to the fund type of the initial account assignment (based from an referenced earmarked document).
After looking in the customizing and in ECC6 PSM Public Sector Management
Release Notes, we are investigating Documentation about Rule-Based Account Assignment Distribution.
Can anybody provides me a link to a documentation, if any?
Otherwise, I would greatly appreciate any help to use this functionality.
Regards,
FrançoisHello,
I am configuring this functionality currently in an ECC 6.0 environment for a public sector organization and have had an issue with the FMSPLITMAINT transaction. When attempting to create a rule the 'create' 'copy' 'change' options are not available.
Configuration has already been completed for Field Profiles, Action Profiles, & Rule Groups.
The olny documentation I have been able to find was an appendix to the SAP Grants Management - Grantee course.
Please respond if you there is any additional documentation which may be of assistance. I have already tried notes: 991661 and 991962.
Thank you -
Questions on Rules-Based ATP and Purchase Requisitions for STOs
Hello experts,
We are working on rules-based ATP configuration and have several questions about the functionality. Iu2019m hoping that some of you are using this functionality and can help give us direction.
In our environment we have multiple distribution centers and multiple manufacturing plants. We want to confirm sales orders against stock and production orders in any of those plants, depending on the locations that have stock or planned production. For example, we will place a sales order against plant A. If there is not enough stock in plant A then rules-based ATP will use location determination to check in plant B, then C. The scope of check on the ATP check will include stock and released production orders. We will configure plant A as the u201Cconsolidation locationu201D so if stock is found in plants B or C then stock transport orders will automatically be created to move the stock to plant A before shipping to the customer.
We have configured rules-based ATP and this functionality is working well in our Development system. The ATP check is executed and uses the rules-based ATP to find eligible stock in other plants. The system is also creating purchase requisitions to move the stock to the consolidation plant.
Our first concern is that there doesnu2019t appear to be any firm linkage between the sales order and the resulting purchase requisition. For example, if we create sales order 123 for plant A and the rules-based ATP finds stock in plant B it automatically creates a purchase requisition 987 to move the stock from plant B to plant A. However, there doesnu2019t appear to be a linkage between sales order 123 and purchase requisition 987. For instance, if we delete sales order 123 the purchase requisition doesnu2019t get deleted.
Our second concern is that the quantity on the purchase requisition can still be confirmed against later sales orders. For example, say the above scenario resulted in a purchase requisition 987 that consumed all the stock available in plant B. We then create a second sales order 456 for the same product. Plant A is out of stock so the rules-based ATP looks in plant B. We would expect that plant B would also not have any stock because itu2019s all been consumed by the purchase requisition. Instead, the system creates a second purchase requisition to move quantity from plant B to plant A. Itu2019s as if the system doesnu2019t realize that the purchase requisition 987 is already planning to move stock out of plant B.
Does anyone have any thoughts or suggestions on these two scenarios? Is there a way to configure the system so there is a hard linkage between the sales order and the purchase requisition so that if the sales order is deleted then the purchase requisition is also deleted? Should ATP realize that purchase orders are consuming inventory and not allow later sales orders to confirm against that same inventory? Any advice or experience would be greatly appreciated.
Thanks,
David Eady

Propex, Inc.Hi,
The scheduling is done in SCM, and from there, whenever the RBA is triggered, the calculation is done always with the old route in SCM. Until you get back to R/3 this is when your route is determined. But the ATP check is always with the original route. So the idea would be that you change the values of the route while still in APO, this is possible via the user exit. Should be done in scheduling in APO.
Hope this information is helpful.

Rule based location substitution:
Hi,
We have the following scenario:
Material : X
Location : A ->B -> C (B is a substitute of A and C is a substitute of B)
ATP position A = 2
B = 2
C = 2
Sales Order of 10 raised at A : Location substitution happens and partially confirms sales order with 6 quantities.
Therefore new ATP position is as below
A = 0
B = 0
C = 0
Now we want to give confirmation(of 4 quantities) based on external lead time to vendor. This will be based on source-list in R/3. The PO to vendor can be based on any of the location based on source-list. i.e. it can be from A,B, or C. The source list is dynamic and can change based on business decision. i.e today the PO plant can be A. It can change tomorrow and be B.
What is the best possible way to model the scenario?
The constraint is that we are not allowed to change the checking rule.
Regards
SameerHi Sameer,
Your scenario is rules based location substitution and then MRP based upon source list.
No matter whether plant A or plant B or C comes on line item , demand should be placed on plant suggested by source list.
I think you can control it using source list field MRP "1 Record relevant to MRP" and planning Plant.
Example : sales order line item plant is A and in source list planning plant is B then , PO will be created at plant B.
Then it will be a two step MRP process:
1.P.O from Plant B to vendor
2. STO from plant B to A.
Thanks

Dear All,
I'm using Rule Based ATP check for Sales Order.
When I conduct ATP simulation in APO (SCM 4.0), the results are perfect. the check triggers the rule and displays schedule lines as per rule. (Location substitution).
But when I conduct availability check in Sales order (R/3 4.7), the results are completely different. For Sales Order at Warehouse, it confirms all the requirement irespective of transportation lane lead time from plant to warehouse. Moreover, when I save the sales order, the PReqs created at Warehouse are in future instead of PReqrel in past. (compared to requirement date). Ideally, the Preqs should have same date as that of requirement date and Preqrel should be created after deducting Transporation lead time and GR/GI time.
I would like to know, what parameters in Sales Order document are used to trigger the rule and how is it different from ATP simulation.
Thank you in advance.

Bipin K UmaraleHi
Take a look at the following SAP Note, it gives all the FAQ's on ATP configuration in R/3, hopefully it will help you with your problem:

Rules based ATP to Consider Checking Horizon
Hello SAP Experts,
I am a novice to GATP functionality. I have one scenario tried to work on it and Standard SAP system doesn't seem to work this way.
Rules based ATP for location Determination is used for order confirmation.
Loc A Mat 1 500 Pcs
Loc B Mat 1 200 Pcs
Rule 1 LocA --> Loc B
Order comes in for Mat 1 at location A for 1000 Pcs and confirmation was given for 700 Pcs out of which 200 Pcs will be sourced from Loc B. I'm trying to confirm remaining 300 at the end of Checking horizon as per Customer requirement. Please suggest a way to acheive this.
Regards,
PriyankaHi,
You will start from ECC, Material master MRP3 view MARC-WZEIT Total replenishment lead time (in workdays).
In APO , SPRO--GATP-Maintain check control - make sure that ATP group and business event example 01 and A should have "consider Checking horizon" .
RLT from R3 will become Checking horizon in product master in APO. In APO product master ATP tab CHKHOR is the field name.
Make sure that in the rules -- calculation profile -allowed delay is not maintained or should not be less than RLT /Checking horizon.

Rule based ATP is not working for Components
Hi All,
Our requirement is to do availability check through APO for Sales order created in ECC,so we are using gATP.
Requirement: We are creating salesorder for BOM header (Sales BOM) and avaialbility check should happen for components i.e. Product avalaibility & Rule based substitution.
Issue: Product availiabilty is working for components but rules based substituion is working, mean Rules are not getting determind for components.
Settings:
- Header doesnot exist in APO and compnents do exist in APO
- Availability check is not enabled for header item category and enabled for Item category for components
- Rules have been created for Components in APO
- Rule base ATP is activated in Check instructions
We have also tried MATP for this i.e. PPM created in APO but still didn't get the desired result.
If we create salesorder for the component material directly then Rule based ATP is happening, so for components Rule based ATP is not working.
How do we enable enable Rulesbased ATP for components, i mean is there any different way to do the same.
Thanks for help.
Regards,
JagadeeshHi Jagdeesh,
If you are creating BOM in ECC and CIFing PPM of FG/Header material to APO, I think you need to CIF Header material, too, with material integration model.
Please include header material in you integration models for material, SO and ATP check as well.
For component availability check, you can use MATP; but for MATP, FG should be in APO. You need not to CIF any receipts of FG (stock, planned orders, POs etc), so that MATP will be triggered directly. Then maintaining Rules for RMs will enable to select available RMs according to the rule created.

Dynamic Rule based implementation in PL/SQL
Hi,
We are trying to implement a dynamic rule based application in Oracle 9i. Its simple logic where we store expressions as case statments and actions seperated by commas as follows.
Rule: 'Age > 18 and Age <65'
True Action: 'Status = ''Valid'' , description = ''age in range'''
False Action: 'Status =''Invalid'', Description=''Age not in range'''
Where Age,Status, description are all part of one table.
One way of implementing this is fire rule for each record in the table and then based on true or false call action as update.
i.e
select (case when 'Age > 18 and Age <65' then 1 else 0 end) age_rule from tableX
(above query will in in a cursor xcur)
Then we search for
if age_rule = 1 then
update tablex set Status = ''Valid'' , description = ''age in range'' where id=xcur.id;
else
update tablex set Status =''Invalid'', Description=''Age not in range'' where id=xcur.id;
end if;
This method will result in very slow performance due to high i/o. We want to implement this in collection based method.
Any ideas on how to dynamically check rules and apply actions to collection without impact on performance. (we have nearly 3million rows and 80 rules to be applied)
Thanks in advanceReturning to your original question, first of all, there is a small flaw in the requirements, because if you apply all the rules to the same table/cols, than the table will have results of only last rule that was processed.
Suppose rule#1:
Rule: 'Age > 18 and Age <65'
True Action: 'Status = ''Valid'' , description = ''age in range'''
False Action: 'Status =''Invalid'', Description=''Age not in range'''
and Rule#2:
Rule: 'Name like ''A%'''
True Action: 'Status = 'Invalid'' , description = ''name begins with A'''
False Action: 'Status =''Invalid'', Description=''name not begins with A'''
Then after applying of rule#1 and rule#2, results of the rule#1 will be lost, because second rule will modify the results of the first rule.
Regarding to using collections instead of row by row processing, I think that a better approach would be to move that evaluating cursor inside an update statement, in my tests this considerably reduced processed block count and response time.
Regarding to the expression filter, even so, that you are not going to move to 10g, you still can test this feature and see how it is implemented, to get some ideas of how to better implement your solution. There is a nice paper http://www-db.cs.wisc.edu/cidr2003/program/p27.pdf that describes expression filter implementation.
Here is my example of two different methods for expression evaluation that I've benchmarked, first is similar to your original example and second is with expression evaluation moved inside an update clause.
-- fist create two tables rules and data.
drop table rules;
drop table data;
create table rules( id number not null primary key, rule varchar(255), true_action varchar(255), false_action varchar(255) );
create table data( id integer not null primary key, name varchar(255), age number, status varchar(255), description varchar(255) );
-- populate this tables with information.
insert into rules
select rownum id
, 'Age > '||least(a,b)||' and Age < '||greatest(a,b) rule
, 'Status = ''Valid'', description = ''Age in Range''' true_action
, 'Status = ''Invalid'', description = ''Age not in Range''' false_action
from (
select mod(abs(dbms_random.random),60)+10 a, mod(abs(dbms_random.random),60)+10 b
from all_objects
where rownum <= 2
insert into data
select rownum, object_name, mod(abs(dbms_random.random),60)+10 age, null, null
from all_objects

if eval = 1 then
execute immediate 'update data set '||rules.true_action|| ' where id = :id' using id;
else
execute immediate 'update data set '||rules.false_action|| ' where id = :id' using id;
end if;
end loop;
end loop;
end;

Re: Oracle 8i (8.1.7.4) Rule based v/s Cost based
Hi,
I would like to know the advantages/disadvantages of using RULE based optimizer v/s COST based optimizer in Oracle 8i. We have a production RULE based database and are experiencing performance issues on some queries sporadically.
TKPROF revealed:
call count cpu elapsed disk query current rows

Please post your expert suggestions as soon as possible.
Thanks and Regards,
AI think the answer you are looking for is that Rule Based optimizer is predictive, but Cost Based optimizer results may vary depending on statistics of rows, indexes, etc. But at the same time, you can typically get better speed for OLTP relational databases with CBO, assuming you have correct statistics, and correct optimizer settings set.

Improving performace for a Rule Based Optimizer DB
Hi,
I am looking for information on improving the current performance of an ancient 35GB Oracle 7.3.4 using RULE based optimizer mode. It is using 160 MB SGA and the physical memory on the system is 512MB RAM.
As of now, all the major tasks which take time, are run after peak hours so that the 130 user sessions are not affected significantly.
But recently am told some procedures take too long to execute ( procedure has to do with truncating tables and re-populating data into it ) and I do see 54% of the pie chart for WAITS are for "sequential reads" followed by "scattered reads" of 36%. There are a couple of large tables of around 4GB in this DB.
Autotrace doesn't help me much in terms of getting an explain plan of slow queries since COST option doesnt show up and am trying to find ways of improving the performance of DB in general.
Apart from the "redo log space requests" which I run into frequently (which btw is something I am trying to resolve ..thanks to some of you) I dont see much info on exactly how to proceed.
Is there any info that I can look towards in terms of improving performance on this rule based optimizer DB ? Or is identifying the top sql's in terms of buffer gets the only way to tune ?
Thank you for any suggestions provided.Thanks Hemant.
This is for a 15 minute internal under moderate load early this morning.

Partitioning on Oracle 8i (Rule Based vs. Cost Based)
At my current engagement, we are using Oracle Financials 11.0.3 on Oracle 8.0.6. The application uses rule-based optimizer. The client wants to implement Oracle partitioning. With this in mind, we are concerned about possible performance issues that the implementation of partitioning may cause since RBO does not recognize it.
We agree that the RBO will see a non-partitioned table the same as a partitioned. In this scenario where you gain the most is with backup/recoverability and general maintenance of the partitioned table.
Nevertheless, we have a few questions:
When implementing partitions, will the optimizer choose to go with Cost base vs. Rule base for these partitioned tables?
Is it possible that the optimizer might get confused with this?
Could it degrade performance at the SQL level?
If this change from RBO to CBO does occur, the application could potential perform poorly because of the way it has been written.
Please provide any feedback.
Thanks in advance.If the CBO is invoked when accessing these tables, you may run into problems.
- You'll have to analyze your tables & ensure that the statistics are kept up to date.
- It's possible that any SQL statements which invoke the CBO rather than the RBO will have different performance characteristics. The SYSTEM data dictionary tables, for example, must use the RBO or their performance suffers dramatically. Most of the time, the CBO beats the RBO, but applications which have been heavily tuned with the RBO may have problems with the CBO.
- Check your init.ora to see what optimizer mode you're in. If you're set to CHOOSE, the CBO will be invoked whenever statistics are available on the table(s) involved. If you choose RULE, you'll only invoke the CBO when the RBO encounters situations it doesn't have rules for.
