BW 3.5 Start Routine Start Routine Code

Question

Hi,
I am writing a Start Routine in BW 3.5 and the logic we have seems to be working but not updating the target ods. We are adding a date field to the target ODS and need to source it from another ODS.  The key structures for each ods is different
Taget ODS:
Header
Line ITem
Schedule Line
Source ODS:
Header
Line Item
When we run the start routine the date field will not update for the schedule lines, it will create a new record in the target ods with the Header Line ITem and Date.
Has anyone had to code this logic before in a 3.5 Start Routine, where you needed to update a date field with ODS with different key strucutures.
Thanks for any help on this issue.

Answer 1

Its difficult in BW 3.5 to include this logic in START_ROUTINE as you cannot add the extra to_date field to the DATA_PACKAGE table.
You need to create a new global internal table with the same structure of DATA_PACKAGE with additional field to_date. then use the logic to fill in the global internal table
define a internal table new_data_package with the required structure like (docno, eventtype, fromdate todate)
data: l_w_datapkg_001 type data_package,
data: l_w_newdatapkg type new_data_package,
data: l_w_datapkg_011 type data_package
LOOP AT DATA_PACKAGE INTO l_w_datapkg_001 WHERE event_type = '001'.
l_w_newdatapkg-docno = l_w_datapkg_001-docno.
l_w_newdatapkg-event_type = l_w_datapkg_001-event_type.
l_w_newdatapkg-fromdate = l_w_datapkg_001-date.
MOVE CORRESPONDING FIELDS OF l_w_datapkg_001 INTO l_w_newdatapkg.
READ TABLE data_package INTO l_w_datapkg_011
WITH KEY docno = l_w_datapkg_001-docno
                 event_type = '011'.
l_w_newdatapkg-to_date = l_w_datapkg_011-date.
APPEND l_w_newdatapkg TO new_data_package          
ENDLOOP.
Now the new datapackage contains the ODS2 data that u needed
