Querying characteristics in Enhanced Material Search

Hi Glen,
I'm glad you are interested in the Enhanced Material Search. I am the solution manager responsible for this function. Your requirement is well known, but so far I don't see a simple, standard worthy solution to allow a search for (hundreds or even thousants of) characteristic values while keeping the user interface simple when selecting or displaying the desired value(s).
Maybe you have an idea for an appropriate customer specific solution that fits your own requirements. Therefore you can use some Business Add-Ins to create customer specific search criteria (see my blog /people/ingo.woesner/blog/2009/03/05/enhanced-material-search-with-creation--part-4-how-to-create-new-search-criteria-wo-modification). Using the badi described therein you could create a new search criteria "Classicification Characteristics " and select specific characteristics. Of course you have to add all characteristics to the SES business object BUS1001006 before, as you have mentioned.
More Business Add-ins for various topics are mentioned in my other blog http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/12999. [original link is broken] [original link is broken] [original link is broken]
I hope this brings you a step further. In case you need more guidance, you can give me a call on +49 6227 771737, and we will then find a time for a webinar/conference call. I will try to get a developer invited as well.

Thanks for your response, Ingo.
Whilst I really like the current design for simple requirements (extend a structure, change some config and, voila!, you have new search criteria), when the requirements become more complicated, it would be nice to have more flexibility to dynamically influence which index is used to do the search. The results of the search could then just feed into the results view as per normal.
Here are a few ideas which are based on my own situation but might be suitable and/or scalable to other situations. I haven't put too much thought into them so they may or may not be feasible.
As mentioned in my original post, we only have a small number of variant classes for which our material variants are created. My thought it that we could create a separate index and business object class for each variant class (all the indexes would be very similar to BUS1001006 but have their own extra attributes for their own characteristics) and a dropdown field on the search view that allows you to choose the variant class via which you want to search. Changing the selection in the dropdown field would change the available search fields in the view and when the search is executed the index that corresponds to the chosen variant class would used for the search.
I'm happy to discuss this further to refine the requirements and/or design.
Regards
Glen

Configuring the Enhanced material search in sales order

I am trying to add our own fields to the extended material search help scren in VA02.
- From the config, logistics-generail/material master/enhanced material search/define search parameters - and in here added the custom fields, whihc happend to be 'Z' fields that we have added to the material characteristics.
- the new fields then appear on the extended material seach screen in VA02, but they don;t retain the data inputtted, or work in the actual search
- AS part of this work we have also configured SES Material Master Business Object BUS1001006 - and setup our own 'Z@ class, whihc adds these 'Z' attributes to the material search help.
- THis all works on the materials search help, but not on the extended material help screen
I have also looked at the BADIs part of the enhanced search help, but these only appear to be called once the results have been extracted. So can anyone give any gudience on how we get the new fields in this screen actually working..

The problem was simple. The table include used field names ZZ, where as all the other besoke fields and data elements were just Z, so once we sync'd everything it magically worked

Enhanced material search with creation

hi guys,
i need your support to start using the enhanced material search in SD environment.
I´ve done the settings in theconfiguration guide mention based on ECC 6.0 EHP2,
but i didnt get the button to start the search in VA01 / VA21 etc !? don´t know why.
Is there anyone having the same problem ?
Isn´t it possible to run this funktion without TREX Search Engine, do i really need
to setup a new server ?!
Looking forward for your help.
Thanks

Enhanced Material search - more than 100 results?

Is there any way to return more than 100 results in the enhanced material search?
Thanks!

Yes this possible - th'o config.
When you do your initial set-up for Configure & Activate Enhanced Search with creation -
> (SPRO>SD>Basis Func-->Add. Func. for Mat) you can specify the search max entries. In your current system, looks like it is defaulted as 100 for that Sales Order Type. You can try changing this & it should work.

Table for characteristics of a material

hi all,
i have a requirement where in i need to add a customized field for characteristics of a material. where can i find the table for charactersitics of a material? i found the structure RCTAV but i could not find the table refering to this structure.
Thanks in advance....
Anil Kumar

chk these FMs
BAPI_OBJCL_GETDETAIL
MATERIAL_READ_CLASSIFIC_RT
also chk this
You can also query tables AUSP and CABN for the data.
AUSP-OBJEK = Matnr
Get the value of ATINN and ADZHL from AUSP for the above value and you should be able to query CABN using these

Query for classfication for material number

Hi,
I would like to create a query that links the material number (MARA) with its assigned classes (in classification in material master) and characteristics for each class. So I want to be able to key in a material number and receive the class and all charateristics and values for that.
Do you know which tables I should join?
Thanks,
Ola

For query you use table AUSP only where Object field is your mateiral number and this will return the value of Char
if you need class also than link the KLAH table
MARA you don't need here and wont link

Enhance product search in ICSS.

Hi Expert,
In ICSS I want to enhance the product search in create service ticket. As a standard functionality you can search product by entering product id or description. I want to enhance that search by catalor id. Means by putting catalog id it should give the corresponding material. We have created ZCATALOG1 and ZCATALOG2 attributes in an index of trexadmin and customized the ICSS UI in such a way that catalog id will come below product id . There you can put the catalog id. Now question is how to assign the search text in ZCATALOG1. Any body has any clue how to it?. It will be really helpfull to me.

Enhance Product Search PRD01QR by Division

Hi,
I need to enhance the product search ( Component PRD01QR) with a new search criteria Division. Could you please advise me on how to achieve the functionality.
Regards,
Kamesh Bathla

Hi Kamesh,
For achieving the above functionality, there are two steps:
1. Enhance the search structure which you have already completed successfully. Add the additional attributes in BOL structue and make them available in UI.
2. Enhance the standard search.
For this, there is a standard BADI definition in CRM: CRM_BADI_RF_Q1O_SEARCH. You need to create a filter dependent implementation for this. In the filter value, specify the name of your search object. In your case, its 'ProdAdvSearchRgProducts'. In the search method of this implemented class, you'll receive your search attributes value in the importing parameters. Write your own dynamic query here based upon your selection criteria and send result list in ET_GUIDLIST structure as returning parameter.
The same result list will be populated in the result list of UI.
The same concept can be adopted for enhancing any search in UI.
I hope my answer helps.
Thanks

Inspection characteristics based on material and goup counter

Hi,
Do we have some function module which would give us inspection characteristics based on material and group counter. I have gone through many posts in this regard but find answers to get inspection characteristics based on inspection lot number.
I do not want to get into quality at all. Is there a FM to get the inspection characteristics based on material and group counter or any related tables would be of gr8 help. T-code QP03 takes material and group counter as input and displays the inspection characteristics. Any input in this regard would be of great help.

Hi,
Use tables MMAPL , MAPL and PLMK as per your requirement.
Thanks,

Characteristics in the material master (SAP Retail)

Hi everybody,
Iu2019m using SAP Retail and I need to maintain characteristics in the material master. These characteristics are used to maintain additional information like u201Caccessoriesu201D and u201Cguaranteeu201D (Iu2019m not working with generic articles and variants).
Each characteristic need to be maintained in different languages:
Example: Guarantee u2013 In Portuguese the value should be u201C2 anosu201D and in English the value should be u201C2 yearsu201D.
There are no predefined values for these characteristics. We use additional values and the user can maintain a free text, but it should be different in Portuguese and in English.
One solution I can use is to create each Characteristic in English and in Portuguese, and then maintain different values for each one. Iu2019m trying to find a better solution because I have numerous Characteristics.
Does anyone know another way to solve this issue?
Thanks in advance,
SN

Hi SN,
this requirement sounds a little bit strange.
Question 1: This field 'Guarantee' is valid for all articles or for some articles only ( e.g merchandise categroy electronics)
Question 2: How do you name the Characteristic? is it Years or Ano or guarantee?
Question 3: using additional vlaues will kick out the value check. So it is like a free text entry. Of course this makes no sense, because you can also add 'g hello' als a valid value.
Why you choose this way ?
Question 4: What is the issue using fixed values? I guess the guarantee values are limited at all.
Question 5: Why you don't use a MARA append field and hide it on unwished mechandise categories. Thats easier to handle and a value check can be implemented. So you are able to create a field with a unit in different languages
e.g. Guarantee Years
if you logon in english.

PS: Did you tried the new characteristic strorage?

Query rewrites with Nested materialized views with different aggregations

Platform used : Oracle 11g.
Here is a simple fact table (with measures m1,m2) and dimensions (a) Location (b) Calendar and (c) Product. The business problem is that aggregation operator for measure m1,m2 are different along location dimension and Calendar dimension. The intention is to preaggregate the measures for a product along the calendar dimension and Location dimension and store it as materialized views.
The direct option is to define a materialized view with Inline queries (Because of the different aggrergation operator, it is not possible to write a query without Inline query). http://download-uk.oracle.com/docs/cd/B28359_01/server.111/b28313/qradv.htm#BABEAJBF documents the limitations that it works only for 'Text match' and 'Equivalent queries' and that is too limiting.
So decided to have nested materialized view, with first view having just joins(my_dim_mvw_joins), the second view having aggregations along Calendar dimension (my_dim_mvw_calendar) and third view having aggregations along the Location dimension(my_dim_mvw_location). Obviously I do not want the query I fire to know about materialized views and I fire it against the fact table. I see that for the fired query (Which needs aggregations along both Calendar and Location), is rewritten with just second materialized view but not the third. (Had set QUERY_REWRITE_INTEGRITY as TRUSTED) .
Wanted to know whether there are limitations on Query Writes with nested materialized views? Thanks
(Have given a simple testable example below. Pls ignore the values given in 'CALENDAR_IDs', 'PRODUCT_IDs' etc as they are the same for all the queries)

This Query rewrites only with my_dim_mvw_calendar. (as saw in Query Plan and EXPLAIN_MVIEW). But we would like it to use my_dim_mvw_location as that has aggregations for both dimensions.

Hi all,
I'm trying to make my programmer's life easier by creating a database view for them to query the data, so they don't have to worry about joining tables. This sounds like a pretty horrible idea. I say this because you will eventually end up with programmers that know nothing about your data model and how to properly interact with it.
Additionally, what you will get is a developer that takes one of your views and see's that of the 20 columns in it, it has 4 that he needs. If all those 4 columns comes from a simple 2 table join, but the view has 8 tables, you're wasting a tonne of resources by using the view (and heaven forbid they have to join that view to another view to get 4 of the 20 columns from that other view as well).
Ideally you'd write stored routines that satisfy exactly what is required (if you are the database resource and these other programmers are java, .net, etc... based) and the front end developers would call those routines customized for an exact purpose.
Creating views is not bad, but it's by no means a proper solution to having developers not learn or understand SQL and/or the data model.

Query on Implicit Enhancement

Hello experts,
I have a query related to enhancing a function module. I am doing phase confirmation of process orders using the BAPI 'BAPI_PROCORDCONF_CREATE_TT' in a module pool program(Z program). I have added few z fields to AFRU. Now i need to enhance the bapi 'BAPI_PROCORDCONF_CREATE_TT' so that the z fields are updated in AFRU. In this bapi i see a function module MAP2I_PI_TIMETICKET_TO_AFRUD in which the z fields can be moved to afrud using an implicit enhancement. But the problem is that the function module MAP2I_PI_TIMETICKET_TO_AFRUD is auto generated and there is a comment in the fm saying 'Dont Change it Manually!!'. Now i need to know how is this function module generated or is there any other way to do phase confirmation of process orders. Pls Help.
Regards,
Ramanan R.S.

Hi Ramanan R.S.,
Function modules MAP2I* and MAP2E* are generated via BDBS transaction.
As your function module is named MAP2I_PI_TIMETICKET_TO_AFRUD, it means that there's a transfer from external to internal (because of MAP2I), and from PI_TIMETICKET structure to AFRUD structure.
But I don't recommend that you work with this one. Create your own MAP2I function module. From BAPIRET2 to BAPIRETURN for instance if you're lazy like me. Store it in your own Z function group, local package.
Before regenerating, you have to look at what was the initial mapping, as it is not stored in a database table, only in the source code. Moreover, it's possible that there were some manual changes before, so they have to be applied manually, so that means a modification of standard if you had worked on a standard one. Copying the MAP2I function module to a Z one before deleting is a very good idea!
- Create your implicit enhancement. Test it.
- In BDBS, you enter transfer from external to internal, plus these 2 names in BDBS, click Generate button.
- It says "already exists", so you have to click the Delete button
- There could be a popup "is still used", click Delete to confirm
- It proposes a default mapping between fields, that can be different from what was previously done.
- That will regenerate the function module (you can make sure by looking at its timestamp).
- Test it again, you'll see that your implicit enhancement is still there.
I admit it doesn't test the situation of a true upgrade, and I don't know any documentation that confirms that the deletion of generated repository object doesn't impact its implicit enhancement. Feedbacks welcome...

Material search by description

Hi,
we want to use TREX for material search from MM03 F4 search .
we are able to search based on material no , EAN no , but not with material description.
I dont want to use full text search field because it do the search on other fields as well.
Let me know what could be the cause that material is not getting searched by description.
Regards
Yashpal Gupta
