Can we create an index for a list of itmes in a single object?

Can we create an index for multiple values in a single object. We have an object Order that contains list of items. I like to get all orders for a specific item. I want to create an index to speed up the query. Is it possible? What are the other alternatives?
My Order object is as follows:
Orders
Item List
Shipping Address
Example:
Order 1
i1, i2, i3, i4
123 some way, city, 12345
Order 2
i2, i3
333 some other way, city2, 33333
order 3
i2, i4, i7
My search would be, give me all orders that has item i2. It should return Order 1, Order 2 and Order 3.
Thanks

Hi,
I think that this will work ...
ValueExtractor extractor= new ReflectionExtractor("getItemList");
cache.addIndex(extractor, true, null);
Set setKeys = cache.keySet(new EqualsFilter(extractor, i2));
In this case, the Collection value extracted by the ValueExtractor is treated as a Collection of contained attributes when the index is created.

Can we create secondary index for a cluster table

hi
can we create secondary index for a cluster table

Jyothsna,
There seems to be some kind of misunderstanding here. You <i>cannot</i> create a secondary index on a cluster table. A cluster table does not exist as a separate physical table in the database; it is part of a "physical cluster". In the case of BSEG for instance, the physical cluster is RFBLG. The only fields of the cluster table that also exist as fields of the physical cluster are the leading fields of the primary key. Taking again BSEG as the example, the primary key includes the fields MANDT, BUKRS, BELNR, GJAHR, BUZEI. If you look at the structure of the RFBLG table, you will see that it has primary key fields MANDT, BUKRS, BELNR, GJAHR, PAGENO. The first four fields are those that all cluster tables inside BSEG have in common. The fifth field, PAGENO, is a "technical" field giving the sequence number of the current record in the series of cluster records sharing the same primary key.
All the "functional" fields of the cluster table (for BSEG this is field BUZEI and everything beyond that) exist only inside a raw binary object. The database does not know about these fields, it only sees the raw object (the field VARDATA of the physical cluster). Since the field does not exist in the database, it is impossible to create a secondary index on it. If you try to create a secondary index on a cluster table in transaction SE11, you will therefore rightly get the error "Index maintenance only possible for transparent tables".
Theoretically you could get around this by converting the cluster table to a transparent table. You can do this in the SAP dictionary. However, in practice this is almost never a good solution. The table becomes much larger (clusters are compressed) and you lose the advantage that related records are stored close to each other (the main reason for having cluster tables in the first place). Apart from the performance and disk space hit, converting a big cluster table like BSEG to transparent would take extremely long.
In cases where "indexing" of fields of a cluster table is worthwhile, SAP has constructed "indexing tables" around the cluster. For example, around BSEG there are transparent tables like BSIS, BSAS, etc. Other clusters normally do not have this, but that simply means there is no reason for having it. I have worked with the SAP dictionary for over 12 years and I have never met a single case where it was necessary to convert a cluster to transparent.
If you try to select on specific values of a non-transparent field in a cluster without also specifying selections for the primary key, then the database will have to do a serial read of the whole physical cluster (and the ABAP DB interface will have to decompress every single record to extract the fields). The performance of that is monstrous -- maybe that was the reason of your question. However, the solution then is (in the case of BSEG) to query via one of the index tables (where you are free to create secondary indexes since those tables are transparent).
Hope this clarifies things,
Mark

Can you create an index on a Map?

I have a few questions that I can't seem to figure out nor find a viable example for. Can you create an index for a Map contained within a nested object, and if so, how would you do this? I currently have a Filter the inspects this criteria in the cache but am unable to figure out to create a usabe index for the custom filter. I'm using Coherence 3.5.2 - any help would be most appreciated. I'm not sure if/what I need to do with the SimpleMapIndex....
Here's the basic object map below. My filter is retrieving all of the CustomerGroup objects that have a Customer in it's collection that contains the passed in Integer value in the Customer's Map. So can you create an Index on a Map (and a nested one at that) and how do you that? The index would need to be on the nested customerValues hashmap.
class CustomerGroup
    Set<Customer> customers ;
class Customer
    Map<Integer, CustumerValue> customerValues;
}

If you write a custom ValueExtractor, which you need to create an index, then you will not need a custom Filter.
Depending on how efficient you need to be you custom extractor can use POF and not have to deserialize the entries to create the index, or it can deserialize the class, which will make the code more straight forward.
For example, without using POF
public class MapKeyExtractor extends EntryExtractor implements PortableObject {
    public MapKeyExtractor() {
    @Override
    public Object extractFromEntry(Map.Entry entry) {
        Set<Integer> keys = new HashSet<Integer>();
        CustomerGroup group = (CustomerGroup) entry.getValue();
        Set<Customer> customers = group.getCustomers();
        for (Customer customer : customers) {
            keys.addAll(customer.getCustomerValues().keySet());
        return keys;
    @Override
    public boolean equals(Object obj) {
        return (obj instanceof MapKeyExtractor);
    @Override
    public int hashCode() {
        return MapKeyExtractor.class.hashCode();
    @Override
    public void readExternal(PofReader in) throws IOException {
        super.readExternal(in);
    @Override
    public void writeExternal(PofWriter out) throws IOException {
        super.writeExternal(out);
}The extractor above will return a collection of all of the Integer values in the keys of all the customerValues of all the customers in a CustomerGroup (I have guessed you might have accessor methods on the classes you posted).
You can then use a ContainsFilter for your query. For example to get all the values from the cache where the customerValues map contains a 19 in the key...
Set results = cache.entrySet(new ContainsFilter(new MapKeyExtractor(), 19));You could write a version of the MapKeyExtractor that uses POF and would not deserialize the values but this would be more complicated code as it would need to extract the Map from the POF stream of the value and walk down the keys and values extracting the keys. It is doable but not worth it unless you are really worried about performance of index updates.
Discalimer I have written the code above from the top of my head so have not compiled it or tested it but it should be OK.

How to create a Index for KM documents

Hi Experts.......
I have two queries .
1,How to create a Index for the KM Server documents so that when ever i am in need of particular document,i can be able to retrive the exact document within short time......
2,What Is TREX? Need of TREX ?
If any one have documents for the above said queries kindly send it to [email protected]
Thanks in Advance,
Jasmine

Hi Jasmine,
1.In the EP 6.0 you can create index System Administration -> System Configuration -> Knowledge Management -> Index Administration
2.TREX is search engine that will proccess the documents that you have specified in the index Data sources when you have created the index.
The status of TREX you can see in System Administration -> Monitoring -> Knowledge Management -> TREX Monitor or Index Monitor for indexing monitoring.
If you don't have connected any TREX engine to J2EE, just start the visual administrator and configure the TREX service.
To install the TREX you can follow the instguides for TREX service.sap.com/instguides SAP Netweaver->Release 04 or 2004s -> Installation -> Cross-NW
I hope that it helps.
Bye

Index - How to create an index for multiple InDesign files?

Hi everyone,
I'm using InDesign CS2 to create a 250 page catalogue. Most of it is finished now, and I've come to creating the index.
The catalogue is spread over about 10 InDesign files. How do I create an index for this? No paragraph styles were set up when it was started, but there are character styles.
I've done some searching - does it need to be booked so I Can index? And can I book it without paragraph styles?
(I've only been using InDesign for about a year, mostly self taught.)
Thanks in advance :)
Naomi

Creating a book from your files should be no problem at all. ID does
i not
synchronize styles across documents -- unless you order it to! (That's what the checkboxes at the left of the book documents are for. Do Not Use, in your case.)
The Index function itself is book-savvy, but you might want to search this forum for a few recurring problems.

How to create a matchcode for the list of Customers "Group key" KNA1-KONZS

Hi All,
with reference to the creation of "Group key" KNA1-KONZS for Customers,
I'd like to know if is possible to create a matchcode for the list of Customers "Group key" created.
Thanks
Gandalf

Hi
MAINTAIN THE GROUP KEY IN GENERAL DATA ---CONTROL DATA SCREEN
If the customer or the vendor belongs to a group, you can enter a group
key here. The group key is freely assignable.
If you create a matchcode using this group key, group evaluations are
possible.

How to create new INDEX for TREX

Hello Experts,
Iam new to this KM and TREX so need ur guidance for this...
I need to create an INDEX for TREX, so after going through various messages i found that it can be created form the Index Administration iView portal----System Administration -> Syetm Configuration -> Knowledge Management -> Index Administration -> New Index
But iam not getting the above path in SPRO OR how to run Index Administration iView OR from which portal i need to create an INDEX??can anyone provide steps on how to go to System Administration -> Syetm Configuration -> Knowledge Management -> Index Administration -> New Index
path.....
Regards.

I'm not very familiar with CRM business partners, but the common way - to include the repository where the documents are stored to the KM using [CM Repository managers|http://help.sap.com/saphelp_nw04/helpdata/en/e3/923227b24e11d5993800508b6b8b11/frameset.htm].
You need first to create a repository manager for you repository and only then you'll be able to create an index.

I have multiple devices (imacs, lap tops and ipads) all connected to a NAS server. Can I create a user for myself and one for my wife, and each have our own apple ID, and Itunes accounts, but all share the same media on NAS drives?

I have multiple devices (iMacs, Lap tops, Ipads) all connected to a Nas Drive. Can I create a user for myself and one for my wife and we each have our own apple ID's, Itunes etc, but share the same data on the hard drives? So when she logs in, and sync's her ipads, they will sync with her stuff and when I do the same under my user account, on the same device, my ipads will sync with my stuff?

You can share the same Apple ID for purchasng form the iTunes and app stores without any problems, but you should all used separate iCloud accounts with separate Apple IDs. (You are not required to use the same ID for iCloud and other services as you do for the iTunes store.) This will prevent you from ending up with merged data. You should also use separate Apple IDs for iMessage and FaceTime or you will end up getting each other's text messages and FaceTime calls.

How can I create a URL for a PWA for MS Project Server 2010 project file that includes the view?

Hi Sander,
As far as I tested it, it is not possible either with PS2010. The URL only contains the PDP name and the projUID.

How can i create a Trash for external USB Drives ?

Hello,
how can i create a Trash for external USB Drives or my TimeCapsule ?
Thanks.

You do not need to create trash cans for individual drives. The trash can on the desktop holds deleted files from all mounted drives.
TimeCapsule manages its own space. If it fills up it will delete older backps to make space for newer ones.

How can I create a form for users wherein the text field will expand to accommodate additional text?

How can I create a form for users wherein the text field will expand to accommodate additional text?

You need to use LiveCycle (PC Only) to create a dynamic form like that.
The best you can do with Acrobat to view all of the text in a field is to set the field to multiline, and set the size to "Auto" (If you don't set the size to 'Auto', you can enter as much text as you wish, but the user will need to use the scrollbar to view all of the text.)

Can we create two POs for the same 3rd party Sales Order?

Hi MM experts,
Issue: Can we create two POs for the same 3rd party Sales Order
In Third party purchase process, first sales order created with a spl. item category and it creates the PR automatically with the Sales order material and Qty and this PR converted PO.
They got a pur.req. for sale order on same item for same delevery date. They did not get any warning msg. saying that a PO was prviously placed against this sale order.
How it is possible that we were able to place another PO? concern is that second PO was palced against SO which was already used & completed. they were able to place 2 POs for the same customer same delevery date. How it is possible?
If anyone face the same issue, please let me know if you have any answer to this questions.
Thanks in advance.
Suresh.

Suresh,
It is hard for me to give you a definitive answer since you have created a customized solution.
How it is possible that we were able to place another PO? concern is that second PO was palced against SO which was already used & completed. they were able to place 2 POs for the same customer same delevery date. How it is possible?
Normally, the system will not do this. A third party PR or PO will be 'account assigned' to the Sales order. SAP standard 3rd party will not create additional purchase reqs unless there has been manual intervention. Try searching for changes in the Sales order and changes in the original purchase order. They may give you a clue.
I believe the normal Item category for third party SO is TAS (I am working from memory here, I am not in front of a system). I don't know what ZTAG does. I confess I am not an SD expert. You might also want to post your question in an SD forum.
You mention two custom applications, ZMMPLAN and ZSTPMP. These somehow have functionality that is used to help you convert your PRs to POs. If I were in your position, I believe I would also look at these applications for clues to how they might be contributing to your problem. And please don't send me details about these apps. I will not comment on custom code in this forum.
Sorry I can't be of more help.

Can v create graphical display for the report

Hi to everyone
my q is this can v create trend lines for a report ........
if the ans is yes then pl mention the way of doing it .......

when you run a bex report on the left top you have a button "graph". If you click this, you get a basic chart representing your output table. when you right-click on the chart you get the option menu as you get in xls, meaning you can change the type of chart (line, bar, pie,...) the series, the titles and so on (like regular xls)
so the answer to your question is yes. If you want even more features you can use workbooks.
