No Source Fields(But wants to read attributes of another master data infoob

Question

Hi
Im planning to use the 2LIS_03_BF datasource. I have two master data infoobjects(0PRODVERS_ATTR, 0MAT_PLANT_ATTR).
Im loading data from 2LIS_03_BF in DSO . But this datasource doesn't contains the source fields for master data infoobjects 0PRODVERS_ATTR, 0MAT_PLANT_ATTR.
So hw can i read the attributes of these master data infoobjects. please let me know

Hi
You can write a routine for this purpose we call it lookup in bw terms ie if the field isnt present in the source then you can take the values from the other targets may it be ods or master data and the selection is based on the keyfields in both the targets ie source field and the target from which the field has to be picked.
lets say i want customer Number  from the MD Customer and i dont have customer number in the souce field so i will write a routine in the start routine to select customer number from customer master data put the field in the internal table and then write a update routine in the field customer number that reads the values into the work area from the internal table and then put the result in the result field from work area.
below is the syntax.
TYPES:BEGIN OF t_custnumber,
***declare the fields u will be using including the keyfileds in the souce**
customer number type /bic/0customer number
END OF t_custnumber.
........internal table to read data into......
DATA : i_custnumber.TYPE STANDARD TABLE OF t_custnumber.
work area to read data from internal table
DATA : wa_custnumber   TYPE t_custnumber,
select
customer number
x
y
from table customer
into i_custnumber
where
x= x of data package ie below ods (source)
y = y of data package ie below ods (source)
The above routine comes in the start routine
Now for the update routine
read table i_custnumber into wa_custnumber with key
x= x of comm_strucute ie below ods (source)
y = y of comm_strucute ie below ods (source)
Result =wa_custnumber-customer number
in start routine the souce table is called as data package but in case of update routine the same souce table is termed as communication structure thus comm_strucuture.
hope this is handy information assign points if applicable
thanks
