Main table vs Look up Table in MDM 7.1

Hi All,
I was looking at major differences between Main table and flat table.My question is what stops me from using my lookuptable as the main table as I can do Syndication,key mapping etc even with my flat tables.(Unless I am wrong in my assumption).
Regards,
Premjit

Hi ,
Maintable will hold data for a particular maste. It contains primary information about a business object such as a product or supplier. Lookup table will be a field which describes the master. you cannot use lookup as a main table because:
1. The data model flexibility to accomodate different data types: such as hiererchies, taxonomies, QT wont be possible using flat lookup tables.
2. Storing such a huge amount of data(lacs of records) in lookup will have lots of performance related issues and will slow down your MDM instance.
3. During integration with Portal it'll be very difficult and will require huge effort to use MDM JAVA API's to fetch/enter data to MDM.
These are few reasons which makes the case of using lookups as MT very weak. There will be more reasons im sure.

Trying to update one table from a second table when data is different

Hello;
I have a the same table in two databases. The database are connected with a DB Link. I am trying to update one of the tables based on the data in the second table when the EMP_ID matches but the LAST_NAME does not match.
The table(s) look like:
Table Name:EMP
EMP_ID
LAST_NAME
FIRST_NAME
MIDDLE_INITIAL
My SQL is:
update EMP TARGET
    set (TARGET.LAST_NAME, TARGET.FIRST_NAME,TARGET.MIDDLE_INITIAL) = (
        select SOURCE.LAST_NAME, SOURCE.FIRST_NAME, SOURCE.MIDDLE_INITIAL
        from EMP@OTHER_DB SOURCE where
        TARGET.PHYSICIAN_ID = SOURCE.PHYSICIAN_ID
        and TARGET.LAST_NAME <> SOURCE.LAST_NAME); This returns an update count of all the rows not the few that I want.
Any help would be great!

Any help would be great!There's no WHERE clause in that UPDATE statement, so every row of the target table will be modified.
if you only want to modify the rows that have a match in the source table, then add a WHERE clause (perhaps "WHERE EXISTS (...) with a sub-query very miuch like the one you already have), or use MERGE instead of UPDATE.
If you'd like help, post CREATE TABLE and INSERT statements to re-create the tables as they exist before the UPDATE, and also post the contents of the changed table after the UPDATE.
Always say which version of Oracle you're using.
Perhaps you want something like this:
{code}
MERGE INTO     emp     target
USING     (
     SELECT     o.emp_id
          ,     o.last_name
          ,      o.last_name
          ,      o.middle_initial
          FROM     emp@other_db     o
          JOIN     emp          t ON     o.emp_id     = t.emp_id
                         AND     o.last_name     != t.last_name
     )          source
ON     (target.emp_id     = source.emp_id
WHEN MATCHED THEN UPDATE
SET     target.last_name     = source.last_name
,     target.first_name     = source.first_name
,     target.middle_initial     = source.middle_initial
{code}
assuming emp is unique, at least in other_db.
This will work in Oracle 10 (and up). In Oracle 9, MERGE always requires a WHEN MATCHED clause, so add one if you must. it doesn't matter what it does; the USING subquery will only return matches.

MDM Data model design for Main table visa vis lookup table

Hi ,
I would like to know whether the legal entities or Address table which are common for all MDM main tables like Customer ,Vendor,Material,Business Partner etc can also become a main table when their attributes are around 30-40 range.
Is it a sound design approach to make Company table with about 50 attributes and say address table with 20 attributes as Main table and replicate a small company-id table with 2 or 3 attributes to link to the main table(company)? This will ensure replicating that small table(company-id) to all other Main tables(customer,vendor,......) instead of replicating that big company table as lookup for all main tables?
Thanks in advance for any idea or feasibility comments.

Hi, Deepak
>>> - How can I populate the data in the lookup table at the same time when I am populating the main table ? I have only the XML's that correspond to the main table . I don't have seperate data for the lookup tables .
I don't think you can populate both main table and all fields of lookup tables at the same time, i.e. using same map. You can consider 2 options to upload all information you have:
1) If your XML file contains data you would like to upload to lookup tables, you can upload it to MDM lookup tables with several maps using same XML and choosing different sections of that XML corresponding to different MDM lookup tables.
2) Also you can upload main table simultaneously with lookup table entries (using same map), but in this case new lookup table entries will only contain display field values that you mapped. To do this you should use 'Add' value mapping functionality for fields that you mapped to lookup tables.
>>>- Can I use the standard maps available for import in the business content of material repository in MDM ?
1) In case you have material master repository delivered by SAP and you use XML files which structure corresponds to SAP predelivered XSD schemas then you can use these maps undoubtedly.
2) If your repository is based on SAP predelivered, but you changed it ,you should adjust these maps due to differences in repository structure and XML files structure.
3) If you created your repository from scratch you should consider option of making your own import maps.

Look up table

I want to prepare a look up table for voltage vs acceleration level in my program. This look up table will be used to search for the level of voltage to be fed to DAQ card for the desired acceleration in my application. Also how to read the look up table...

Hi Puneet,
Take a look at the "write to spreadsheet file.vi" and the "read from spreadsheet file.vi". This is one way to accomplish what I think you're looking to do.

Maintaining Remote key in look up tables for Production data

Hi,
me
SEE in DEV and QA to maintain the Remote key for Look up tables.First i have exported those look up table values and again imported with mapping Remote keys (clone the field and map it to Remote key.). By this i have maintained the Remote keys to all look up tables. Now for Production what should i do. Is it the same process extract all records from production into our desktop and then again import it using IM, clone the field and map it to Remote key.
1. Is this the right process?
2. What happens if there are huge data present in production how to proceed furthr then?
Required your suggestion please.
Thanks,
Pradeep

HI Pradeep,
I dont see any problem with this method if I am getting it right
You are updating remote keys by reimporting lookup data, and this way you have multiple remote keys for data in lookup table,right?
This will help you to automap entries in Import process for different Remote systems.
I did not get your 2nd point?
Thanks,
Ravi

Code is not working check for solution . The code is not working after look up table.

In this code i am multiplying two binary images , one is a rectangle and another is an image. i am getting the rectangle, but not the image. The image part is not working after the look up table. Waiting for the solution

Hey. I'm thinking the problem is in theis block:
LOOP AT C_T_DATA INTO WA_MC17I30HDR.
   READ TABLE LT_AFIH
     WITH KEY AUFNR = WA_MC17I30HDR-AUFNR
     INTO WA_AFIH BINARY SEARCH.
   IF SY-SUBRC = 0.
     WA_MC17I30HDR-ZZNPLDA = WA_MHIS-NPLDA.
     MODIFY C_T_DATA FROM WA_MC17I30HDR.
ENDIF.
ENDLOOP.
You are reading LT_AFIH into WA_AFIH. But then you are assigning NPLDS from WA_MHIS. From what I can see, WA_MHIS hasn't been filled with anything. Try changing:
     WA_MC17I30HDR-ZZNPLDA = WA_MHIS-NPLDA.
To:
     WA_MC17I30HDR-ZZNPLDA = WA_AFIH-NPLDA.
Hope that does the trick.
Thanks

How to use database look up table function in xsl mapping

Can anybody tell me how to use database look up table function while mapping xsl between 2 nodes.
I have an XML file coming in and depending on one of XML elements we need to decide which further path to take. But, using this XML element, we need to query database table, get metadata and accordingly take appropriate path. I have written lookup function which returns metadata value.
Now, the issue is how do I pass the XML element valu as input to look up function? When I tried to drag it to the input node of lookup function, it throws an error like "Maximum number of parameters exceeded"
Thanks,

If the lookup table is always going to remain the same (e.g. a character generator or something similar) you can place the values in a 2D array constant on your diagram, with the input value as one column, the equivalent as the other. When you need to perform the lookup you use an index array to return all the values in the "input column", search it using "search 1D array" and use the resulting index number to index the other column's data. If the values may change, then it would probably be best to load an array control with your equivalent values from a file.

Hi Venkat,
Two things -One is the performance and the other ... there is no Append within the loop.
Try moving the select statement ousdie the loop to improve performance and move the modify statement into the loop ... change modify to append. Code below.
   Let me know if you need more help.

Looking for table that links a PM Reservation to a MM Purchase Requisition

Looking for table that links a PM Reservation to a MM Purchase Requisition

Hi,
Typically the way most SAP systems are configured, there are two scenarios here:
1. The component reserved in the PM order is item category 'N'. This is a non inventory item and must be directly procured for consumption against the PM order at the point of goods receipt. In this case no reservation is created and instead a requisition is directly created (in table EBAN) and the requisition is account assigned directly to the PM order (in table EBKN - field AUFNR).
2. The component reserved in the PM order is item category 'L'. In this case no requisition is directly created, instead a reservation is created against the item in stock (in table RESB). If there is sufficient stock of the item already then the item is consumed when it is goods issued to the PM order from stock using MIGO and there is no requisition created. In the event that there is not sufficient stock of the item for the reservations that exist, when MRP is run, a requisition will be created to replenish the stock, but this requisition will not be assigned to a specific PM order as it could be replenishing stock of the item for several reservations which are all for different orders. So in this scenario there is no direct link from the reservation generated by the PM order to the requisition.

How to make a magnifying glass link to a look up table ?

Dear Friends,
Hello. I am developing the accounting application of journal entry. In journal line, I use the image "magnifying glass" next to each chart field. When we click on the magnifying glass, it's supposed to come up a look up table( a chart and name mapping table), and we select the proper chart to input into the chart field.
I understand to create another record and page for the look up table. But I don't understand how to make a magnifying glass link to a look up table. Can anybody tell me how to do that ? Thanks.
Lucy

This is how it works,
Table A (which stores chart fields). You have used fields from table A on a page so that users can input data.
You don't need to put a magnifying glass image or create a new page to achieve look up page.
all you need to do is create another table say Table B which should have the chart field and corresponding description you want to show on lookup page. Then open record-field property of the chart field on Table A and mention Table B as prompt table.

2 different tables in the main window with same internal table data

Hi All,
can we have 2 diffterent tables with same internal table data into its work area in the main window.Is it possible or we will get any run time error.?
is it like having 2 nested loop with same internal table ?
ex : loop at itab1 into wa_itab.
loop at itab1 into wa_itab.
endloop.
endloop.
can we use like this?

Hi,
there will not be any error ...but what is the use of it...
do you need to have a controlled way of display ...of the data...
If so then you create another workarea in the global definitions of the same type and then use it...

How to read data from spreadsheet as a look up table

Hello Can anybody please help me out in this..??
I want to read data from a spreadsheet file as it is a look up table.
I want to create a program which lets the user enter an element which is be found in the data in the spreadsheet file and gives back the number which is to the adjoining column of the element in the spreadsheet file.
Example i have the following data in spreadsheet file:
Range Count
2              10
4              49
6              60
Etc.
If i enter 2 to search the data in the spreadsheet file, i do expect the program replies back with the answer 10 and so on...
Can anyone please help out...
Thanks in advance...
