Adding a Field in a Transaction Datasource

Question

Hi,
I have created a ZAUTH InfoObject in BI for the field Authorization group (BEGRU - MARA).  This ZAUTH Infoobject is getting filled in through Master data Load of 0MATERIAL.  I have added the Infoobject ZAUTH as a Navigational Atttribute in 0MATERIAL.
I have created a Billing DSO for the Transaction load which gets data through the Datasource 2LIS_12_VDITM.  In DSO, i have a requirement wherein i have to write a routine using 0customer & Authorization group (ZAUTH).  The requirement goes like this:
  If the Customer number = 100 & Authorization = ABC, Put Detail = Stock.
  If the Customer number = 200 & Authorization =  XYZ, Put Detail = Trade.
The Problem here is i dont have the BEGRU field in the Transaction Datasource 2LIS_12_VDITM.  I know we can customize the Datasource & add this field.  But, is there any other way to do this?
Regards,
Murali

I guess you can realize this requirement without enhancing the datasource. There is 1:1 relationship between material and auth group as it is added as an attribute on it. You can derive the auth group by looking up material master data in the code, for the material on the billing document. Once this is derived you can build your logic for detail. You need to derive auth group at a lower level in the data flow and put logic for detail at the next level or you can consider using start (derive auth group) and end routines (logic for Detail).
