Lookup in BI Transformations

Question

Hi Experts,
My requirement is to write a lookup in transformations
While loading data from DSO 1 to CUBE I need to perform a select statement on DSO A and with the results from select statement I need to again perform select on to a DSO B and get the values which I can use in result fields.
I am familiar with first select statement on DSO A and moving the data to a internal table, But I couldn’t able to figure it out  how can I write second select statement and align the results to the same internal table so that I can read it in end routine.
Please help me with pseudo code….
Any questions please let me know

HI,
try the below code here 2 select statements. looking up  the 2 DSO's.
TYPES : begin of ty_ds200,
         HE_STUDNT TYPE /BI0/OIHE_STUDNT,
         HE_STAGE TYPE /BI0/OIHE_STAGE,
         END OF ty_ds200 .
data : lt_ds200 type TABLE OF ty_ds200,
        ls_ds200 type ty_ds200 .
TYPES : BEGIN OF ty_dso400 ,
         HE_STUDNT TYPE /BI0/OIHE_STUDNT,
         /BIC/ZLC_GEO TYPE /BIC/OIZLC_GEO,
   END OF ty_dso400 .
data : lt_dso400 TYPE TABLE OF ty_dso400 ,
        ls_dso400 TYPE TY_dso400 .
if RESULT_PACKAGE is NOT INITIAL .
   SELECT HE_STUDNT HE_PRGRM HE_STAGE from /BI0/AHE_DS0200 into TABLE
  lt_ds200
     FOR ALL ENTRIES IN RESULT_PACKAGE
     WHERE HE_STUDNT = RESULT_PACKAGE-HE_STUDNT.
   SELECT HE_STUDNT HE_STORGP HE_STORGA HE_STCAMP  from
   /BI0/AHE_DS0400
     INTO TABLE lt_dso400 for ALL ENTRIES IN RESULT_PACKAGE
     WHERE HE_STUDNT = RESULT_PACKAGE-HE_STUDNT
     and DATETO = '99991231'.
   loop at RESULT_PACKAGE ASSIGNING <RESULT_FIELDS> .
     READ TABLE lt_ds200 into ls_ds200 WITH KEY HE_STUDNT =
     <RESULT_FIELDS>-HE_STUDNT .
Hope it will help.
Thanks,
Phani.
