Rule based GUIs
Hi!
I�ve been doing a lot of Java GUIs lately, and I am starting to be tired of always defining the same checks to user inputs.
Things like:
- having 2 date fields and one cannot be older that the other
- certify that a text field cannot have certain characters
- disable buttons components while the user has not filled something.
What I have been doing is writing all this checks in the code. But sometimes I need to change something in the forms and I have more work to be done.
I was wondering if there is any kind of framework that could help me with this. Something that I could systematically define rules for or relations between fields and reuse it. In the end based on its results, should apply some action (like print a error message or enable a continue button).
If there is, does it worth the work or should I be more methodic when building a GUI to not change it later?
Does this requirement have a �well know name� that I can google for?
Thanks,
Eduardo
eduram,
I haven't come across such a framework, but then again I haven't gone looking. I'd be really surprised if there isn't something out there that does this, however--a SourceForge project, perhaps? Heck, we even have aspect oriented programming for free here!
If I were to write this, my approach would be the following:
1) write down a list of common scenarios (as you've done)
2) write "validator" classes that valiate String input
3) write "adapter" classes that adapt widget properties to the format required by validators. This way adapters have specific knowledge of widgets, but validators don't. Attach adapters as listeners to widgets.
4) for extra credit, develop a declarative (likely XML-based) syntax to describe widget interrelations. Use reflection to 'figure out' widget properties.

Rule-based or 'expert' system in Oracle
Hi,
Has anyone implemented a rule-based system in Oracle? E.g. based upon a decision tree?
I have a feeling that the algorithm will involve 'tree-walking' within a heirarchy of rules but I'm not quite sure how to structure it. I have a couple of ideas such as storing pointers to the next rule with the columns holding things like the name of the parameter, the condition, the comparison value and the outcome.
The program has to choose a carrier (such as UPS or Fed-Ex) based upon rules such as the weight (<1kg?>, the intrinsic value (> #100), the addressee postcode and whether the package is hazardous or not. There can be any permutaion of these conditions apart from those that are direct opposites (such as greatr than or lower than 1kg).
I would be grateful for any advice on this, or a web address that might help (I have googled and found something calld the 'reme algorithm' but cannot find any elaboration of it! grrr.....).
Thanks for your time,
Regards,
Jim.thanks for your reply, but need different thing,
suppose we prepare a report in report builder and when we want to print it, it always print in windows gui fonts like times new roman, arial , tahoma etc..
I WANT TO PRINT IT IN TEXT-BASED FONTS NOT WINDOWS FONT WHICH GAIN HIGH QUANTITY OF TONER . I want to print like IBM COBOL, FOXPRO, GWBASIC, PASCAL TEXT MODE REPORTS -
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.

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,

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.

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

loop
fetch data_cursor into eval, id;
exit when data_cursor%notfound;
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
Parse 0 0.00 0.00 0 0 0 0

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.

My organization has an application that needs a very fine grained scurity model, that changes very often and is based upon a rules machnisem (written in PL/SQL). Is there a way to combine a rule based mechanism with the internal ACL mechanism of the iFS ?
nullHi Harvey_SO,
According to your description, you get the security ignored when using custom dynamic role-based security. Right?
In Analysis Services, it has some role overlapping scenarios, if two roles used to secure attributes in two different dimensions, which might both apply to some users simultaneously, it can cause the user has no security applied from either role. Please
refer to workarounds in the link below:
The Additive Design of SSAS Role Security
If you have any question, please feel free to ask.

we have an airline pricing system whose rules change often, and rather than re-designing tables and the client application code everytime that happens, we would like to develop a rule-based system to dynamically store the rules in a rule-based system that doesn't require re-design and code modification.
any ideas ?
here is an example of the data that we would like to store
if seasonality is LOW
and passenger is CHILD
and carrier is TRW
and origination is COS
and destination is PIT
and ticket code is Y
then price is 908
seasonality for carrier TRW is LOWfor travel between 01/15/06 to 04/15/06
seasonality for carrier JAR is LOW for travel between 02/01/06 to 05/01/06
age for carrier TRW is CHILD for passenger age betwen 2 and 12
age for carrier JAR is CHILD for passenger age between 6 and 14
.. and another price can be given with an entirely different set of rules
reason is ask in this forum is I read a blog of someone who praises the set-based nature of the SQL language for developing exactly this kind of system, rather than trying to implement it on the client (for example using JRules)What version of Oracle are you on? 10g introduced a rules engine into the database (Oracle Rules Manager and/or Oracle Expression Filter) which would seem to be right up your alley.

Connect SharePoint to SQL Server Database Then Build Rules Based Returns System
Hello Guys,
I work for an ecommerce business. We sell a wide range of products to customers all around the world which are ordered from our websites and then dispatched to our customers from our warehouses.
I have been tasked with developing a computerised return system from the company because at the moment everything is done using paper forms.
We have all our customer, order and product data within SQL Server databases.
What I would like to know is...
1. Can we connect sharepoint online to a local sql server database
2. Could we then build searches within sharepoint to display data contained within these databases e.g. customer information etc
3. How is the data presented in sharepoint - is there a way to design how the data is displayed within sharepoint etc?
4. Can we then build a rules based return system within sharepoint? The on screen workflow would need to vary according to data contained within the database e.g. the weight if the product being returned and also on fields input by the service agent such
as the reason for the return, what solution the customer would like etc.
5. is it possible to build these workflows in such a way that they can be saved part way through then gone back to later
6. Can reports be build based on the returns that are being generated e.g. list of products most commonly returned
Sorry for all the questions, I am a bit of sharepoint novice. I think it may possible be able to do what we need but I just wondered if the answer to any of the above questions is definately a no because if it is that could mean it is not suitable
ThanksYou could use a BCS connection
http://community.office365.com/en-us/b/office_365_community_blog/archive/2012/10/11/business-data-connectivity-services-in-office-365-sharepoint-online.aspx, this will allow you to edit data in your non SharePoint SQL DB, on premises, from Office 365 SharePoint.
Search will index the web applications you point it at, and the lists from the BCS will be part of those web apps, site collections, sites at some place and will get indexed.
You can create views on the data, that can sort of work like a search, but when you search on the site where the lists are the query will return results based on the BCS data.
These views can be based on criteria such as the weight of the product being returned and other fields.
The data is presented as a list.
You can make it read only or read-write based on SharePoint permissions on the list. The account used to create the connection can edit.
BCS is possible in on-premises SharePoint too
here is a good read on it,

Job Chain. How to create Rule based on Time also?
Hi ,
I need to check at 9:30 AM that one of the previous step in the existing chain has been completed.
If not I'd like to do some 'send_notification' Step.
So, I need to create rule based on Time and 'step_n succeeded'.
Could you please tell me how to do that?
Thanks for your help,
LSY.Hi,
Alberto is right in his approach. You can't say to evaluate the chains rules at 9:30am but you can set an evaluation context of 10 minutes so that the chains rules are reevaluated every 10 minutes.
Then you can create a rule that says
if the time is between 9:30am and 9:40am and step_to_check is running or not_started
then start send_notification_step
Hope this helps,

APO Rule based ATP for RA Repair
Hey,
Could you please help me to turn on rule based ATP for document type RA outbound?
The senario is as follows:
Customer returns to my company the product.
My company has multiple locations (plants) for replacement products. I would like to determine the replacement product location with rule-based ATP. We use rule-based ATP for the sales site w/o issues.
I set up in configuration:
ZRA (copy of RA) with business transaction RMA(to trigger the rule based ATP)
Assigned ZRA / Item usage = R104/ PSTYV= ZXNN (item category allows rule based ATP).
ZRA ZNO1 R104 IRRA ZXNN
I also did the below rules based ATP item catgegory determination:
AUART MTPOS VWPOS UEPST PSTYV
ZRA ZNO1 APO0 ZTP1 ZXNN
ZRA ZNO1 APO1 ZTP1
ZRA ZNO1 APO1 ZXNN ZTP1
ZRA ZNO1 APO2 ZTP1 ZXNN
When I create with VA01 a ZRA order and add a replacement plant then I get this message:
The ATP rules are not called up for item 000030 - Message no. /SAPAPO/ATP147
But when I go from the "APO Availability Check" view to the Rule then I see my rules determined.
The detail message also says that the system "things" the line was already delivered, which is not the case.
Could you please tell me if it is possible to combine rule-based ATP with the RA replacement process and if yes how to do it?
Thanks,

Rule Based ATP- Error in calling up function 'BAPI_APOATP_CHECK' in APO ser
Hi Experts
I hae configured Rule Based ATP with Multi-Level ATP check. I have completed all configuration required for Rule Based ATP but still facing an error
" Error in calling up function 'BAPI_APOATP_CHECK' in APO server 'SC5CLNT001': Check instructions 30 / A does not exist for locat"
Have any of you ever encountered this error?
Regards,
Sushovan DattaDear Sushovan,
Most likely cause of the above error is a missing requirement class in R/3 and missing Check mode in APO for material and plant combination.
Please read the F1-Help for field check mode in APO:
"Together with the business event, the check mode derived from the product master defines the type and scope of the checks carried out. It also controls forecast consumption.
SD (R/3) uses the requirement class of the requirement as check mode. As of R/3 Plugin 2000.1, the requirement class is transferred (via the strategy group in the material master) to the location-specific APO product master (ATP tab page). In the process, no plausibility check is carried out. For this reason, you should not enter any other check mode in the product master. (The check mode in the product master must agree with the requirement class from the R/3 system.)"
So please create for your material in corresponding plant the requirement class ' 030' assigned to the strategy group in MRP3 in R/3 and the same in the check mode field in //mat1 in APO.
Afterwards the gatp check will find the check mode and business event (check instructions) and the error will be not appear again.
Regards,
Tibor
