Multiple Main Table Question

Question

I am new to MDM 7.1 & Multiple Main Tables. I have a very basic questionu2019
My Requirement is that I have to keep Two Main Tables,
1.      Manufacturer Parts Master Table and the key is Manufacturer Name + Manufacturer Part No (Two fields)
2.      I  have another Main Table  called Manufacturer Parts Table and key will be Manufacturer Name + Manufacturer Part No (Two fields)
My requirement is  that when I load data in to the 2nd Main table (Manufacturer parts Table) I have to validate against the Master table (Manufacturer Parts  Master Table) with the key combination of Manufacturer Name + Manufacturer Part No  and that this key combination must exists in the 1st table.( Manufacturer Parts Master Table.). If  not then it is an error.
I know we can use the 1st table as lookup main table for the 2nd table but do we need to combine the key fields Manufacturer Name + Manufacturer Part No for both the tables to validate against the Manufacturer Parts Master table with the same key combination?.
Anyone explains how I can do this?
Also, Qualified tables still exits in MDM 7.1? OR we have to use  Tuples?

Answer 1

Hi,
1. Manufacturer Parts Master Table and the key is Manufacturer Name + Manufacturer Part No (Two fields)
In Console: Say your 1st main table has Manufacturer Name + Manufacturer Part. No two fields which are Display fields. For this 1st Main table you should have your Edit Key mapping = Yes.
In Import Manager: Your Remote Key in your MDM import Manager should be mapped with combination of these two fields using Partition Concept with some delimiter say ,
e.g. for 1 record in your 1st main table when you right click on your Edit key mapping using MDM data Manager it has values as:
RemoteSystem Key
ABC MANF1,123
So here Key is combination of Manufacturer Name + Manufacturer Part No (MANF1,123) which has delimiter ,
2. I have another Main Table called Manufacturer Parts Table.
In Console: For this 2nd Main table first of all, you will create a Field of type Lookup Main which is lookup to 1st main table say X. You will have some other field too in 2nd main table which is Display field and using it you can import data.
In Import Manager: For 2nd Main table, your source fields again should be combination of Manufacturer Name + Manufacturer Part No using partition field concept with delimiter say , and map this Partition field here with field X which is lookup to main table. when you will do this you will see all your source values for this partition field gets mapped automatically for the records which are present in 1st main table and if there is any value which is not mapped it means that that manufacturer name + manufacturer Part no does not exist in 1st main table.
You must set this property in Import Map, if you are importing data through Import server by right clicking on target mapped field X Set MDIS Unmapped Value handling = Fail which will take care if record exists in 1st main table then only record imported in 2nd main table else give error. As if record exists in 1st main table then while importing data through 2nd main table his value automatically gets mapped.
Also, Qualified tables still exits in MDM 7.1? OR we have to use Tuples?
For most of standard Master's e.g. Material SAP Note 1355137, Customer SAP Note 1412742: Tuple has been replaced using  Qualified table. But if you want, you can model data as per your requirement. You can still use Qualified table if business demands.
