POSDM/Aggregates.

Hi All,
Can anyone help me out in getting information of how to use Aggregates in POSDM.Please let me know if there is any reference material available on this.
Regards,
Sid.

Hi
Agreeagte Sales is, at Store POS System transfers the day end sales business transactions to IS-retail system through Idocs.
The inventory management, billing, information system, and replenishment planning functions are supplied with the aggregated sales data. Here, you determine how the aggregated sales data is to be prepared and forwarded to the various functions.
Use
The settings control the subsequent functions after inbound processing, such as billing, inventory management, and updates in the RIS.
The entered calculation schema controls account determination in accounting for cash payment
Prerequisites
Number ranges have been maintained for customers (external number assignment).
The calculation schema (ZPOSCS) and POS inbound profile KASI /PSNA have been defined in the system.
TO do this, Need to do some Config settings in Retail system
SPRO > Sales and Distribution > POS Interface > Inbound > Agreeated Sales control > POS inbound profile
Here need to chek conrtol fields -
Anonym. Customer ( walkin customers)
Inventory managment,
billing,
sales doc type, & item catgy,(if differs from std)
billing type (FP - POS billing type)
Calculation schmea - (Std -POS000)
No of items per document
POS condition type
The day end in Retail system need to run transaction code WPUK to look agreegate sales.

Setting aggregation level in POSDM

Hi experts
I would like to consult from you regarding SAP standard function on aggregation level to be set in POSDM.
The requirement I get is to aggregate sales in the level of day/store/article/promotion ID.
Are there any solution to this in terms of configuration?
Really appreciate your help.

Dominic

Hi,
Aggregation Method plays a key role in terms of One-Step Processing Tasks.For eg.,if you want to Generate WPUTAB Idoc and there is an aggregation Method code which is specifically available to have the aggregation done based on the means of payment.
SImilarly you can have aggregation method based on material,by sales item and qualifier and also with material&Conditions combination.
You can see the difference when you choose 0000 - Code for Aggregation method for Task code 0013 - Generate Idoc WPUTAB and process.Later on change the Code for Aggregation Method to 0005 and you can see if in POS Workbench also.
NOTE : You can also custom specific Aggregation Method - for eg, Aggregation should be done based on transaction type/sales item type etc.
Thanks and Regards,

TRIGGERING IDOCs IN TWO STEP PROCESSING POSDM ?

Hello Experts,
Could you please explain me why the two step processing is used in POSDM? Is it due to better performace?
And also how the IMG configuration is handled? Once the aggregate tasks are processed how do we TRIGGER THE IDOCS?
Thanks,
Alex

Hi,
You trigger the IDoc creation via transaction /POSDW/ODIS.
The reason for the 2 step processing a quite a lot. One example is performance. In a 2 step scenario you can trickle tha data during the day and add them to an aggregate as they come into POS DM. At the end of the day you only need to trigger the second step which is simply moving the data fromt the aggregate to an interface.
Furthermore it is much easier to trace the data flow as you can see what line items went into which aggregate and which aggregate has been pushed into which idoc.

Index's on cubes or Aggregates on infoobjects

Hello,
Please tell me if it is possible to put index's on cubes; are they automatically added or is this something I put on them?
I do not understand index's are they like aggregates?
Need to find info that explains this.
Thanks for the hlep.
Newbie

Indexes are quite different from aggregates.
An Aggregate is a slice of a cube which helps the data retrival on a faster note when a query is executed on a cube. Basically it is kind of a snapshot of KPI's and Business Indicators (Chars) which will be displayed as the initial query run result.
Index is a process which is inturn will reduce the query response time. While an object gets activated, the system automatically create primary indexes. Optionaly, you can create additional index called secondary indexes.Before loading data, it is advisable to delete the indexes and insert them back after the loading.
Indexes act like pointers for quickly geting the Data.When u delete it will delete indexes and when u create it will create the indexes.
When loading we delete Bcs during loading it has to look for existing Indexes and try to update so it will effect the Data load performence so we delete and create it will take less time when compared to updating the existing ones.
There is one more issue we have to take care if u r having more than 50 million records this is not a good practice insteah we can delete and create during week end when they r no users.

How can I see the data in the aggregates

how can see the data available in the aggregates.
Jay

Hi Jay,
its so simple,
please goto the manage aggregates screen and copy the technical name of the aggregate and add
/bic/exxx xxx is the aggregate technical name, and for f fat table use /bic/fxxx, and go to se16 and enter the table name and thats it ur data is with u.

Aggregates, VLAN's, Jumbo-Frames and cluster interconnect opinions

Hi All,
I'm reviewing my options for a new cluster configuration and would like the opinions of people with more expertise than myself out there.
What I have in mind as follows:
2 x X4170 servers with 8 x NIC's in each.
On each 4170 I was going to configure 2 aggregates with 3 nics in each aggregate as follows
igb0 device in aggr1
igb1 device in aggr1
igb2 device in aggr1
igb3 stand-alone device for iSCSI network
e1000g0 device in aggr2
e1000g1 device in aggr2
e1000g2 device in aggr3
e1000g3 stand-alone device of iSCSI network
Now, on top of these aggregates, I was planning on creating VLAN interfaces which will allow me to connect to our two "public" network segments and for the cluster heartbeat network.
I was then going to configure the vlan's in an IPMP group for failover. I know there are some questions around that configuration in the sense that IPMP will not detect a nic failure if a NIC goes offline in the aggregate, but I could monitor that in a different manner.
At this point, my questions are:
[1] Are vlan's, on top of aggregates, supported withing Solaris Cluster? I've not seen anything in the documentation to mention that it is, or is not for that matter. I see that vlan's are supported, inluding support for cluster interconnects over vlan's.
Now with the standalone interface I want to enable jumbo frames, but I've noticed that the igb.conf file has a global setting for all nic ports, whereas I can enable it for a single nic port in the e1000g.conf kernel driver. My questions are as follows:
[2] What is the general feeling with mixing mtu sizes on the same lan/vlan? Ive seen some comments that this is not a good idea, and some say that it doesnt cause a problem.
[3] If the underlying nic, igb0-2 (aggr1) for example, has 9k mtu enabled, I can force the mtu size (1500) for "normal" networks on the vlan interfaces pointing to my "public" network and cluster interconnect vlan. Does anyone have experience of this causing any issues?
Thanks in advance for all comments/suggestions.

For 1) the question is really "Do I need to enable Jumbo Frames if I don't want to use them (neither public nore private network)" - the answer is no.
For 2) each cluster needs to have its own seperate set of VLANs.

Aggregates on Non-cumulative InfoCubes, stock key figures, stock, stocks,

Hi..Guru's
Please let me know if anybody has created aggregates on Non-Cumulative Cubes or key figure (i.e. 0IC_C03 Inventory Management.)
I am facing the problem of performance related at the time of execution of query in 0IC_C03.( runtime dump )
I have tried lot on to create aggregate by using proposal from query and other options. But its not working or using that aggr by query.
Can somebody tell me about any sample aggr. which they are using on 0ic_c03.
Or any tool to get better performance to execute query of the said cube.
One more clarification req that what is Move the Marker pointer for stock calculation. I have compressed only two inital data loading req. should I compress the all req in cube (Regularly)
If so there would be any option to get req compress automatically after successfully load in data target.
We are using all three data sources 2lis_03_bx,bf & um for the same.
Regards,
Navin

Hi,
Definately the compression has lot of effect on the quey execution time for Inventory cubes <b>than</b> other cumulated cubes.
So Do compression reqularly, once you feel that the deletion of request is not needed any more.
And ,If the query do not has calday characterstic and need only month characterstic ,use Snap shot Info cube(which is mentioned and procedure is given in How to paper) and divert the month wise(and higher granularity on time characterstic ,like quarter & year) queries to this cube.
And, the percentage of improvement in qury execution time in case of aggregates is less for non cumulated cubes when compared to other normal(cumulated) cubes. But still there is improvement in using aggregates.

Re: How to Improve the performance on Rollup of Aggregates for PCA Infocube

Hi BW Guru's,
I have unresolved issue and our team is still working on it.
I have already posted several questions on this but not clear on how to reduce the time on Rollup of Aggregates process.
I have requested for OSS note and searching myself but still could not found.
Finally i have executed one of the cube in RSRV with the database selection
"Database indexes of an InfoCube and its aggregates" and got warning messages i was tried to correct the error and executed once again but still i found warning message. and the error message are as follows: (this is only for one info cube we got 6 info cubes i am executing one by one).
ORACLE: Index /BI0/IACCOUNT~0 has possibly degenerated
ORACLE: Index /BI0/IPROFIT_CTR~0 has possibly degenerated
ORACLE: Index /BI0/SREQUID~0 has possibly degenerated
ORACLE: Index /BIC/D1001072~010 has possibly degenerated

ORACLE: Index /BIC/QGMAPPC2~0 has possibly degenerated
ORACLE: Index /BIC/SGMAPGP1~0 has possibly degenerated
i don't know how to move further on this can any one tell me how to tackle this problem to increase the performance on Rollup of Aggregates (PCA Info cubes).
every time i use to create index and statistics regularly to improve the performance it will work for couple of days and again the performance of the rollup of aggregates come down gradually.
Thanks and Regards,
Venkat

hi,
check in a sql client the sql created by Bi and the query that you use directy from your physical layer...
The time between these 2 must be 2-3 seconds,otherwise you have problems.(these seconds are for scripts that needed by Bi)
If you use "like" in your sql then forget indexes....
For more informations about indexes check google or your Dba .
Last, i mentioned that materialize view is not perfect,it help a lot..so why not try to split it to smaller ones....
ex...
logiacal dimensions
year-half-day
company-department
fact
quantity
instead of making one...make 3,
year - department - quantity
half - department - quantity
day - department - quantity
and add them as datasource and assign them the appropriate logical level at bussiness layer in administrator...
Do you use partioning functionality???
i hope i helped....

Questions regarding aggregates on cubes

Can someone please answer the following questions.
1. How do I check whether someone is re-bilding aggregates on a cube?
2. Does rebuilding an aggregate refer to the rollup process? Can it take a few hours?
3. What does it mean when someone switches off an aggregate, basically what is the difference (conceptually/time consumption)between:
                        A. activating an aggregate?
                        B. switching off/on an aggregate?
                        C. rebuilding an aggregate?
3. When a user complains that a query is running slow, do we build an aggregate based on the chars in rows & free chars in that query OR is there anything else we need to include?
4. Does database statistics in the 'MANAGE' tab of a cube only show statistics or does it do anything to improve the load/query performance on the cube?
Regards,
Srinivas.

1. How do I check whether someone is re-bilding aggregates on a cube?
If your aggregate status is in red and you are filling up the aggregate - it is an initial fill of the aggregate and filling up would mean loading the data from the cube into the aggregate in full.
2. Does rebuilding an aggregate refer to the rollup process? Can it take a few hours?
Rebuilding of an aggregate is to reload the data into the aggregate from the cube once again.
3. What does it mean when someone switches off an aggregate, basically what is the difference (conceptually/time consumption)between:
A. activating an aggregate?
this would mean recreating the data structures for the aggregate - this would mean dropping the data and reloading the data.
B. switching off/on an aggregate?
Switching off an aggregate means that it will not be used by the OLAp processor but would mean that the aggregate still gets rolled up. Rollup referring to loading changed data from the cube into the aggregate - this is done based n the requests that have not yet been rolled up into the cube.
C. rebuilding an aggregate?
Reloading data into the aggregate
3. When a user complains that a query is running slow, do we build an aggregate based on the chars in rows & free chars in that query OR is there anything else we need to include?
Run the query in RSRT and do an SQl view of the query and check the characteristics that are used in the query and then include the same into your aggregate.
4. Does database statistics in the 'MANAGE' tab of a cube only show statistics or does it do anything to improve the load/query performance on the cube?
Stats being updated will improve the execution plans on the database. Making sure that stats are up to date would lead to better execution plans and hence possibly better performance but it cannot eb taken for granted that refreshing stats is going to improve query performance.

Back end activities for Activation & Deactivation of Aggregates

Hi ,
Could any body help me to understand the back-end activites performed at the time of activation and deactivation of aggregates.
Is filling of Agreegate is same as Roll up?
What is the diffrence between de-activation and deletion of Aggregate?
Thanks.
Santanu

Hi Bose,
Activation:
In order to use an aggregate in the first place, it must be defined activated and filled.When you activate it, the required tables are created in the database from theaggregate definition. Technically speaking, an aggregate is actually a separate BasicCube with its own fact table and dimension tables. Dimension tables that agree with the InfoCube are used together. Upon creation, every aggregate is given a six-digit number that starts with the figure1. The table names that make up the logical object that is the aggregate are then derived in a similar manner, as are the table names of an InfoCube. For example, if the aggregate has the technical name 100001, the fact tables are called: /BIC/E100001 and /BIC/F100001. Its dimensions, which are not the same as those in the InfoCube,have the table names /BIC/D100001P, /BIC/D100001T and so on.
Rollup:
New data packets / requests that are loaded into the InfoCube cannot be used at first for reporting if there are aggregates that are already filled. The new packets must first be written to the aggregates by a so-called “roll-up”. In other words, data that has been recently loaded into an InfoCube is not visible for reporting, from the InfoCube or aggregates, until an aggregate roll-up takes place. During this process you can continue to report using the data that existed prior to the recent data load. The new data is only displayed by queries that are executed after a successful roll-up.

Aggregate build suggestions

Hello Experts,
We are trying to do performance tuning on a BW3.5 setup ... Currently, we are focusing on queries and looking at the feasibility of building aggregates for performance improvement. We find that most queries see data at the very granular level as follows:
Rows
Profit centre group -> Profit Centre-> Product hierarchy level 1
Columns
Actual , Planed, difference.
Now the proposal generated for the queries do not give profit centre group but only profit centre in the first dimension. Please note that profit centre group is a navigational attribute of profit centre( There is a message that says profit centre cannot be in aggregate because of presence of profit centre group)
Now my question is , in order for these queries to hit the aggregate, should I introduce both Profit centre group and Profit centre in the aggregate? In doing so, will I risk creating a bigger aggregate?
I am not sure if I am making sense. But please feel free to ask questions I will explain more if needed. My question to be precise is, whether all the characteristics required to view the data in a query needs to be present in the aggregate?
Many thanks in advance for all your inputs..
Regards,
Solomon

Hi Solomon,
If your query has to hit the aggregate, then all the characteristics in the selection, filter, default values, rows, columns, used in RKFs, used in exceptional aggregation should be present in the aggregate.
You can execute the query in RSRT ->Execute+Debug-> with Display aggregate found option.
This will tell you exactly what are the characteristics those should be present so that your default view hits the aggregate.
Needless to say, if you are planning to drilldown the report with any characteristic from the free characteristics, even that should be present in the aggregate.
Now coming to your confusion on Profit centre and Profit Centre Group, Since profit centre group is already navigational attribute of profit centre you need not ( can not ) place that in the aggregate, when profit centre is already present.
However, if the query is executed with this nav attribute, it will certainly hit the aggregate ( Can be checked in RSRT ).
Thanks,
Krishnan

Key Figure Aggregate in Bex Query

Hi Gurus
I am using BI7.0; but 3.5x BEx tools
I am loading 6 fields from a flat file. I am loading data for tickets. I have create an InfoObject that counts the number of tickets. No problem. Also I also have key figures that I am assigning the same value to all Charactersitics: 10,30 per ticket.
The Key figures are (Sum) with a Summation aggregation type.
In my Query, the 10,30 aggregate up based on the number of tickets (characteristic) that are available.
Question: How do I remove/stop my key figures from aggregating up (sums) the values of 10, 30 based on the charactersitic? I want only 10, 30 to be present regardless of the number of tickets (constant value applied to the key figure).
Should I change my aggregation type? If so, to what? I see a number of options, such as Last Number, No aggregation, etc
Thank you

I found a solution to my requirement.

Key figure fixing in aggregate level partially locking

Hi Guys,
When fix the cell in the planning book, getting "One or more cells could not be completely fixed" message.
1. If a material having only one CVC in the MPOS those quantity can be fixed correctly without any issues.
2. If a material having more than 1 CVC combination and try to fix one of the CVC combination quantity, it is fixing partially and getting the above message.
3. Even, it is not allowing to fix the quantity in aggregate level also.
We are in SCM 7.0.
Is there precondition that need to fix the material having only one CVC combination.
Even a material having multiple CVC combination why it is not allowing to fix one CVC combination in detail level.
Is aggregate level key figure fixing is not allowed ?
Please clarify.
Thanks
Saravanan V

Hi,
It is not mandatory to assign Standard KF to be able to fix. However your custom infoobject that you created must be of type APO KF and not BW KF.
That said, Let us try and address your first problem.
You can fix at an aggregate level. However there a few points to remember.
Let us consider a couple of scenarios.
1) In your selection id, it is showing a number of products. You are selecting all the products at one go and load the data and try to fix at this level. This is not possible.
2) In your selection id, you have selected a product division. For a single product division you are loading data and try to fix at this level. This is the true aggregate level and it should be possible at this level.
Hope this helps.
Thanks

Effect of Full Attribute Extract on Aggregate Attribute Change Run

Because we extract data that does not trigger the change pointer on 0CUST_SALES we do a FULL extract of this data daily instead of a DELTA. We recently created an aggregate which contains navigational attributes of 0CUST_SALES (namely Sales Office & Sales Group).
My question is does the system look to see if any information has changed between the new and old values or does it assume since there is a new version for every entry that 100% of the values have changed?
The reason I'm asking is BW appears to be rebuilding this aggregate from scratch each day instead of changing the aggregate for the few entries that actually changed.

I did a FULL extract for 0CUST_SALES in our QA system. It transferred 28617 records. When I look into the monitor > processing > data package 1 > update I see the following:
3 data records in table /BI0/XCUST_SALES marked for deletion
3 data records inserted in table /BI0/XCUST_SALES
3 data records n table /BI0/PCUST_SALES marked for deletion
3 data records inserted in table /BI0/PCUST_SALES
Different database operations were executed
When I run the attribute change I see the following messages:
The Change Run is executing
Attribute 0CUST_SALES__ZZROUTE for basic characteristic 0CUST_SALES: 2 changes
Attribute 0CUST_SALES__0BILLTOPRTY for basic characteristic 0CUST_SALES: 2 changes
Attribute 0CUST_SALES__0PAYER for basic characteristic 0CUST_SALES: 2 changes
Attribute 0CUST_SALES__ZZACGRP for basic characteristic 0CUST_SALES: 2 changes
0001 ZSD_C02    100016     Aggregates Will Be Adjusted by:Reconstruction
0002 ZSD_C02    100019     Aggregates Will Be Adjusted by:Reconstruction
After seeing this i revisited the documentation for threshold value in RSCUSTV8. Ours is BLANK! So according to the documents when it is blank the aggregate is reconstructed generally. Not what we want!!
I will change the setting to the suggested 20% to start and we'll work from there.
Thanks for your help Oliver.
