Disaggregation Best Practice

Hello,
What are the best practices for disaggregation in APO? Is there any good documentation for when to use each type of disaggregation? If so, please forward to me. Can anyone explain exactly how the "generate proportional factors" program in APO works? If I only used the S-Pro rata method and I have existing data at the lower levels, do I even need to generate proportional factors in order for disaggregation to work correctly?
Thanks

Hi
The SAP APO help on <a href="http://help.sap.com/saphelp_scm50/helpdata/en/66/29fb672fbe11d398240000e8a49608/content.htm">Generation of Prop factors</a> would be helpful
Also read the link from there on the disaggregation
Proportional factors are used as a common base, in order to do realistic disaggregation in cases where you dont have data for all levels. They are generated based on historical (or in some cases planning) data
and stored in the KF for prop factors- APODPDANT
In planning area setuyp you set some KF to disaggregate based on another KF or APODPDANT.
you dont have to generate prop factors if you dont have I or P in your KF aggregation type

Updating of data in APO DP - what is 'best practice'?

I am using APO DP V5.
I am using XI as an integration broker to receive data from external sources which is to be loaded into APO DP.
There are of course different ways of doing this, for example:
1. From XI, pass an XML message which then loads a delta queue in APO BW, loads an InfoCube, which is then used to load data into an APO planning area
2. From XI, pass the data into BAPI parameters, which are then used to directly update data in an APO planning area via a BAPI call (eg BAPI PlanningBookAPS)
What is the recommended 'best practice' here?
Thanks,
Bob Austin

Hi Bob,
I do not have experience in SCM 5.0 and XI but shall give my views from general experience.
What kind of data you are loading in APO DP is the driver for the two ways mentioned by you.
Traditionally (older versions of SCM/APO and non XI interface) Sales History is captured into an Infocube and then loaded to DP Planning Area. The reason - you normally use this Infocube for generation of CVCs which is the Master Data in APO DP. Moreover you will use this data to generate Proportional Factors for disaggregation of Statistically generated Forecast at aggregate level to the lowest level. So there is a requirement for loading Historical data from external systems to APO DP via an Infocube.
The other kind of data would be market and sales forecast. This is a timeseries data which need to be directly loaded to the Planning Area for immediate Interactive Planning. In that case rather than putting it in an Infocube and then periodically loading the data from the Infocube to the Planning Area, its better to load the data directly in the Planning Area. There the BAPI will be a good option.
Hope this gives some ideas to your query.
Thanks,

SAP SCM and SAP APO: Best practices, tips and recommendations

Hi,
I have been gathering useful information about SAP SCM and SAP APO (e.g., advanced supply chain planning, master data and transaction data for advanced planning, demand planning, cross-plant planning, production planning and detailed scheduling, deployment, global available-to-promise (global ATP), CIF (core interface), SAP APO DP planning tools (macros, statistical forecasting, lifecycle planning, data realignment, data upload into the planning area, mass processing u2013 background jobs, process chains, aggregation and disaggregation), and PP/DS heuristics for production planning).
I am especially interested about best practices, tips and recommendations for using and developing SAP SCM and SAP APO. For example, [CIF Tips and Tricks Version 3.1.1|https://service.sap.com/form/sapnet?_FRAME=CONTAINER&_OBJECT=011000358700006480652001E] and [CIF Tips and Tricks Version 4.0|https://service.sap.com/form/sapnet?_FRAME=CONTAINER&_OBJECT=011000358700000596412005E] contain pretty useful knowledge about CIF.
If you know any useful best practices, tips and recommendations for using and developing SAP SCM and SAP APO, I would appreciate if you could share those assets with me.
Thanks in advance of your help.

Hi Jarmo,
Apart from what DB has suggested. you should give a good reading on the following.
-Consulting Notes (use the application component filters in search notes)
-Collective Notes (similar to the one above)
-Release Notes
-Release Restrictions
-If $$ permit subscribe to www.scmexpertonline.com. Good perspective on concepts around SAP SCM.
-There are a couple of blogs (e.g. www.apolemia.com) .. but all lack breadth.. some topics in depth.
-"Articles" section on this site (not all are classified well.. see in ECCops, mfg, SCM, Logistics etc)
-Serivce.sap.com- check the solution details overview in knowledge exchange tab. There are product presentations and collaterals for every release. Good breadth but no depth.
-Building Blocks - available for all application areas. This is limited to vanilla configuration of just making a process work and nothing more than that.
-Get the book "Sales and Operations Planning with SAP APO" by SAP Press. Its got plenty of easy to follow stuff, good perspective and lots of screen shots to make life easier.
-help.sap.com the last thing that most refer after all "handy" options (incl. this forum) are exhausted. Nevertheless, this is the superset of all "secondary" documents. But the maze of hyperlinks that start at APO might lead you to something like xml schema.
Key Tip: Appreciate that SAP SCM is largely driven by connected execution systems (SAP ECC/ERP). So the best place to start with should be a good overview of ERP OPS solution overview, at least at the significant level of depth.). Check this document at sdn wiki "ERP ops architecture overview".
I have some good collection of documents though many i havent read myself. If you need them let me know.

Logical level in Fact tables - best practice

Hi all,
I am currently working on a complex OBIEE project/solution where I am going straight to the production tables, so the fact (and dimension) tables are pretty complex since I am using more sources in the logical tables to increase performance. Anyway, what I am many times struggling with is the Logical Levels (in Content tab) where the level of each dimension is to be set. In a star schema (one-to-many) this is pretty straight forward and easy to set up, but when the Business Model (and physical model) gets more complex I sometimes struggle with the aggregates - to get them work/appear with different dimensions. (Using the menu "More" - "Get levels" does not allways give the best solution......far from). I have some combinations of left- and right outer join as well, making it even more complicated for the BI server.
For instance - I have about 10-12 different dimensions - should all of them allways be connected to each fact table? Either on Detail or Total level. I can see the use of the logical levels when using aggregate fact tables (on quarter, month etc.), but is it better just to skip the logical level setup when no aggregate tables are used? Sometimes it seems like that is the easiest approach...
Does anyone have a best practice concerning this issue? I have googled for this but I haven't found anything good yet. Any ideas/articles are highly appreciated.

Hi User,
For instance - I have about 10-12 different dimensions - should all of them always be connected to each fact table? Either on Detail or Total level.It not necessary to connect to all dimensions completely based on the report that you are creating ,but as a best practice we should maintain all at Detail level only,when you are mentioning any join conditions in physical layer
for example for the sales table if u want to report at ProductDimension.ProductnameLevel then u should use detail level else total level(at Product,employee level)
Get Levels. (Available only for fact tables) Changes aggregation content. If joins do not exist between fact table sources and dimension table sources (for example, if the same physical table is in both sources), the aggregation content determined by the administration tool will not include the aggregation content of this dimension.

Best practices for setting up users on a small office network?

Hello,
I am setting up a small office and am wondering what the best practices/steps are to setup/manage the admin, user logins and sharing privileges for the below setup:
Users: 5 users on new iMacs (x3) and upgraded G4s (x2)
Video Editing Suite: Want to connect a new iMac and a Mac Pro, on an open login (multiple users)
All machines are to be able to connect to the network, peripherals and external hard drive. Also, I would like to setup drop boxes as well to easily share files between the computers (I was thinking of using the external harddrive for this).
Thank you,

Add fields in transformations in BI 7 (best practice)?

Hi Experts,
I have a question regarding transformation of data in BI 7.0.
Task:
Add new fields in a second level DSO, based on some manipulation of first level DSO data. In 3.5 we would have used a start routine to manipulate and append the new fields to the structure.
Possible solutions:
1) Add the new fields to first level DSO as well (empty)
- Pro: Simple, easy to understand
- Con: Disc space consuming, performance degrading when writing to first level DSO
2) Use routines in the field mapping
- Pro: Simple
- Con: Hard to performance optimize (we could of course fill an internal table in the start routine and then read from this to get some performance optimization, but the solution would be more complex).
3) Update the fields in the End routine
- Pro: Simple, easy to understand, can be performance optimized
- Con: We need to ensure that the data we need also exists (i.e. if we have one field in DSO 1 that we only use to calculate a field in DSO 2, this would also have to be mapped to DSO 2 in order to exist in the routine).
Does anybody know what is best practice is? Or do you have any experience regarding what you see as the best solution?
Thank you in advance,
Mikael

Hi Mikael.
I like the 3rd option and have used this many many times. In answer to your question:-
Update the fields in the End routine
- Pro: Simple, easy to understand, can be performance optimized - Yes have read and tested this that it works faster. A OSS consulting note is out there indicating the speed of the end routine.
- Con: We need to ensure that the data we need also exists (i.e. if we have one field in DSO 1 that we only use to calculate a field in DSO 2, this would also have to be mapped to DSO 2 in order to exist in the routine). - Yes but by using the result package, the manipulation can be done easily.
Hope it helps.

Temp Tables - Best Practice

Hello,
I have a customer who uses temp tables all over their application.
This customer is a novice and the app has its roots in VB6. We are converting it to .net
I would really like to know the best practice for using temp tables.
I have seen code like this in the app.
CR2.Database.Tables.Item(1).Location = "tempdb.dbo.[##Scott_xwPaySheetDtlForN]"
That seems to work, though i do not know why the full tempdb.dbo.[## is required.
However, when i use this in the new report I am doing I get runtime errors.
i also tried this
CR2.Database.Tables.Item(1).Location = "##Scott_xwPaySheetDtlForN"
I did not get errors, but I was returned data i did not expect.
Before i delve into different ways to do this, i could use some help with a good pattern to use.
thanks

Hi Scott,
Are you using the RDC still? It's not clear but looks like it.
We had an API that could piggy back the HDBC handle in the RDC ( craxdrt.dll ) but that API is no longer available in .NET. Also, the RDC is not supported in .NET since .NET uses the framework and RDC is COM.
Work around is to copy the temp data into a data set and then set location to the data set. There is no way that I know of to get to the tempdb from .NET. Reason being is there is no CR API to set the owner of the table to the user, MS SQL Server locks the tempdb to that user has exclusinve rights on it.
Thank you

Best Practice for Significant Amounts of Data

This is basically a best-practice/concept question and it spans both Xcelsius & Excel functions:
I am working on a dashboard for the US Military to report on some basic financial transactions that happen on bases around the globe. These transactions fall into four categories, so my aggregation is as follows:
Year,Month,Country,Base,Category (data is Transaction Count and Total Amount)
This is a rather high level of aggregation, and it takes about 20 million transactions and aggregates them into about 6000 rows of data for a two year period.
I would like to allow the users to select a Category and a country and see a chart which summarizes transactions for that country ( X-axis for Month, Y-axis Transaction Count or Amount ). I would like each series on this chart to represent a Base.
My problem is that 6000 rows still appears to be too many rows for an Xcelsius dashboard to handle. I have followed the Concatenated Key approach and used SUMIF to populate a matrix with the data for use in the Chart. This matrix would have Bases for row headings (only those within the selected country) and the Column Headings would be Month. The data would be COUNT. (I also need the same matrix with Dollar Amounts as the data).
In Excel this matrix works fine and seems to be very fast. The problem is with Xcelsius. I have imported the Spreadsheet, but have NOT even created the chart yet and Xcelsius is CHOKING (and crashing). I changed Max Rows to 7000 to accommodate the data. I placed a simple combo box and a grid on the Canvas u2013 BUT NO CHART yet u2013 and the dashboard takes forever to generate and is REALLY slow to react to a simple change in the Combo Box.
So, I guess this brings up a few questions:
1)     Am I doing something wrong and did I miss something that would prevent this problem?
2)     If this is standard Xcelsius behavior, what are the Best Practices to solve the problem?
a.     Do I have to create 50 different Data Ranges in order to improve performance (i.e. Each Country-Category would have a separate range)?
b.     Would it even work if it had that many data ranges in it?
c.     Do you aggregate it as a crosstab (Months as Column headings) and insert that crosstabbed data into Excel.
d.     Other ideas that Iu2019m missing?
FYI: These dashboards will be exported to PDF and distributed. They will not be connected to a server or data source.
Any thoughts or guidance would be appreciated.
Thanks,
David

Best-practice for Catalog Views ? :|

Hello community,
A best practice question:
The situtation: I have several product categories (110), several items in those categories (4000) and 300 end-users. I would like to know which is the best practice for segment the catalog. I mean, some users should only see categories 10,20 & 30. Other users only category 80, etc. The problem is how can I implement this ?
My first idea is:
1. Create 110 Procurement Catalogs (1 for every prod.category). Each catalog should contain only its product category.
2. Assign in my Org Model, in a user-level all the "catalogs" that the user should access.
Do you have any idea in order to improve this ?
Saludos desde Mexico,
Diego

Hi,
Your way of doing will work, but you'll get maintenance issues (to many catalogs, and catalog link to maintain for each user).
The other way is to built your views in CCM, and assign these views to the users, either on the roles (PFCG) or on the user (SU01). The problem is that with CCM 1.0 this is limitated, cause you'll have to assign one by one the items to each view (no dynamic or mass processes), it has been enhanced in CCM 2.0.
My advice:
-Challenge your customer about views, and try to limit the number of views, with for example strategic and non strategic
-With CCM 1.0 stick to the procurement catalogs, or implement BADIs to assign items to the views (I experienced it, it works, but is quite difficult), but with a limitated number of views
Good luck.

Best practice on sqlite for games?

Hi Everyone, I'm new to building games/apps, so I apologize if this question is redundant...
I am developing a couple games for Android/iOS, and was initially using a regular (un-encrypted) sqlite database. I need to populate the database with a lot of info for the games, such as levels, store items, etc. Originally, I was creating the database with SQL Manager (Firefox) and then when I install a game on a device, it would copy that pre-populated database to the device. However, if someone was able to access that app's database, they could feasibly add unlimited coins to their account, unlock every level, etc.
So I have a few questions:
First, can someone access that data in an APK/IPA app once downloaded from the app store, or is the method I've been using above secure and good practice?
Second, is the best solution to go with an encrypted database? I know Adobe Air has the built-in support for that, and I have the perfect article on how to create it (Ten tips for building better Adobe AIR applications | Adobe Developer Connection) but I would like the expert community opinion on this.
Now, if the answer is to go with encrypted, that's great - but, in doing so, is it possible to still use the copy function at the beginning or do I need to include all of the script to create the database tables and then populate them with everything? That will be quite a bit of script to handle the initial setup, and if the user was to abandon the app halfway through that population, it might mess things up.
Any thoughts / best practice / recommendations are very appreciated. Thank you!

I'll just post my own reply to this.
What I ended up doing, was creating the script that self-creates the database and then populates the tables (as unencrypted... the encryption portion is commented out until store publishing). It's a tremendous amount of code, completely repetitive with the exception of the values I'm entering, but you can't do an insert loop or multi-line insert statement in AIR's SQLite so the best move is to create everything line by line.
This creates the database, and since it's not encrypted, it can be tested using Firefox's SQLite manager or some other database program. Once you're ready for deployment to the app stores, you simply modify the above set to use encryption instead of the unencrypted method used for testing.
So far this has worked best for me. If anyone needs some example code, let me know and I can post it.

Best Practice Table Creation for Multiple Customers, Weekly/Monthly Sales Data in Multiple Fields

We have an homegrown Access database originally designed in 2000 that now has an SQL back-end. The database has not yet been converted to a higher format such as Access 2007 since at least 2 users are still on Access 2003. It is fine if suggestions
will only work with Access 2007 or higher.
I'm trying to determine if our database is the best place to do this or if we should look at another solution. We have thousands of products each with a single identifier. There are customers who provide us regular sales reporting for what was
sold in a given time period -- weekly, monthly, quarterly, yearly time periods being most important. This reporting may or may not include all of our product identifiers. The reporting is typically based on calendar-defined timing although we have
some customers who have their own calendars which may not align to a calendar month or calendar year so recording the time period can be helpful.
Each customer's sales report can contain anything from 1,000-20,000 rows of products for each report. Each customer report is different and they typically have between 4-30 columns of data for each product; headers are consistently named. The
product identifiers included may vary by customer and even within each report for a customer; the data in the product identifier row changes each week. Headers include a wide variety of data such as overall on hand, overall on order, unsellable on hand,
returns, on hand information for each location or customer grouping, sell-through units information for each location or customer grouping for that given time period, sell-through dollars information for each location or customer grouping for that given time
period, sell-through units information for each location or customer grouping for a cumulative time period (same thing for dollars), warehouse on hands, warehouse on orders, the customer's unique categorization of our product in their system, the customer's
current status code for that product, and so on.
Currently all of this data is stored in a multitude of Excel spreadsheets (by customer, division and time period). Due to overall volume of information and number of Excel sheets, cross-referencing can take considerable time. Is it possible to
set-up tables for our largest customers so I can create queries and pivot tables to more quickly look at sales-related information by category, by specific product(s), by partner, by specific products or categories across partners, by specific products or
categories across specific weeks/months/years, etc. We do have a separate product table so only the product identifier or a junction table may be needed to pull in additional information from the product table with queries. We do need to maintain
the sales reporting information indefinitely.
I welcome any suggestions, best practice or resources (books, web, etc).
Many thanks!

I assume you want to migrate to SQL Server.
Your best course of action is to hire a professional database designer for a short period like a month.
Once you have the database, you need to hire a professional DBA to move your current data from Access & Excel into the new SQL Server database.
Finally you have to hire an SSRS professional to design reports for your company.
It is also beneficial if the above professionals train your staff while building the new RDBMS.
Certain senior SQL Server professionals may be able to do all 3 functions in one person: db design, database administration/ETL & business intelligence development (reports).

Best Practice to fetch SQL Server data and Insert into Oracle Tables

Hello,
I want to read sqlserver data everry half an hour and write into oracle tables ( in two different databases). What is the best practice for doing this?
We do not have any database dblinks from oracle to sqlserver and vice versa.
Any help is highly appreciable?
Thanks

Well, that's easy:
use a TimerTask to do the following every half an hour:
- open a connection to sql server
- open two connections to the oracle databases
- for each row you read from the sql server, do the inserts into the oracle databases
- commit
- close all connections

Best Practice for Image placement and Anchored Frames for use in Robohelp 9

Hi,
I'm looking for the best practices in how to layout my images in Framemaker 10 so that they translate correctly to Robohelp 9. I currently have images inside of Anchored frames that "Run into" the right side of my text. I've adjusted the size of the anchored frame so that my text flows correctly around the image. Everything looks good in Framemaker! Yeah! The problem is that when I link my Framemaker document to Robohelp, the text does not flow around my image in the same manner. On a couple of Robohelp screens the image is running into the footer. I'm wondering if I should be using tables in Framemaker in order to get the page layout that I'm looking for. Also, I went back and forth...is this a Framemaker question or is this a Robohelp question. Any assistance would be greatly appreciated.

Best practice for a same query against 2 different tables

Hello all,
I want to extract info about tablespaces storage, both permanent and temporary. For that I use 2 different cursors that do exactly the same query but against a different table (dba_data_files and dba_temp_files).
CURSOR permanentTBSStorageInfo (tablespaceName VARCHAR2) IS
SELECT file_name, bytes, autoextensible, maxbytes, increment_by
FROM dba_data_files
WHERE tablespace_name = tablespaceName;
CURSOR temporaryTBSStorageInfo (tablespaceName VARCHAR2) IS
SELECT file_name, bytes, autoextensible, maxbytes, increment_by
FROM dba_temp_files
WHERE tablespace_name = tablespaceName;
First I'm bothered that I have to use 2 cursors to execute the same query against 2 different tables. Is there no another way around?
Then I fetch the results of this cursors in 2 different loops because I didn't find a way to dynamically call the cursors. I am looking for best practice here, knowing that I will do the same parsing against the results of the 2 cursors.
Thank you,

Best practice for if/else when one outcome results in exit [Bash]

I have a bash script with a lot of if/else constructs in the form of
if <condition>
then
<do stuff>
else
<do other stuff>
exit
fi
This could also be structured as
if ! <condition>
then
<do other stuff>
exit
fi
<do stuff>
The first one seems more structured, because it explicitly associates <do stuff> with the condition. But the second one seems more logical because it avoids explicitly making a choice (then/else) that doesn't really need to be made.
Is one of the two more in line with "best practice" from pure bash or general programming perspectives?

I'm not sure if there are 'formal' best practices, but I tend to use the latter form when (and only when) it is some sort of error checking.
Essentially, this would be when <do stuff> was more of the main purpose of the script, or at least that neighborhood of the script, while <do other stuff> was mostly cleaning up before exiting.
I suppose more generally, it could relate to the size of the code blocks. You wouldn't want a long involved <do stuff> section after which a reader would see an "else" and think 'WTF, else what?'. So, perhaps if there is a substantial disparity in the lengths of the two conditional blocks, put the short one first.
But I'm just making this all up from my own preferences and intuition.
When nested this becomes more obvious, and/or a bigger issue. Consider two scripts:
if [[ test1 ]]
then
if [[ test2 ]]
then
echo "All tests passed, continuing..."
else
echo "failed test 2"
exit
fi
else
echo "failed test 1"
fi
if [[ ! test1 ]]
then
echo "failed test 1"
exit
fi
if [[ ! test2 ]]
then
echo "failed test 2"
exit
fi
echo "passed all tests, continuing..."
This just gets far worse with deeper levels of nesting. The second seems much cleaner. In reality though I'd go even further to
[[ ! test1 ]] && echo "failed test 1" && exit
[[ ! test2 ]] && echo "failed test 2" && exit
echo "passed all tests, continuing..."
edit: added test1/test2 examples.
