How can I consume an analytical query in ABAP ?
Normally analytical queries are used with reporting tools like SAC, Analysis Office, WebDynpro Grid, or RSRT in backend.
This post show how to directly access and use the query within your own ABAP application by the use of
Lightweight
BICS
API ( LBA ) .
It's really easy and needs only 2 ABAP calls . Development was driven by the need for testing the query with unit test. But for sure this approach also fits to others usecase where you want to use the query in your ABAP application.
This example show the most simple case. Calling a query without variables.
DATA(lr_std_query) = NEW cl_lba_std_query( i_query_name = 'MyQueryName' ).
lr_std_query->get_resultset(
"EXPORTING i_t_requested_columns = lt_requested_columns "dimensions&keyfigures for resultset
" i_t_variable_values = lt_variable "mandatory and optional variables
" i_t_filter_values = lt_filter "additional filters
IMPORTING e_r_resultset = DATA(lr_resultset) "resultset table
e_t_column_catalog = DATA(lt_column_catalog) ). "resultset description
LBA comes also with a 2nd flavours to call the CDS based query.
DATA(lr_std_query) = NEW cl_lba_cds_query( i_view_name = 'MyCDSview' ).
lr_cds_query->get_resultset( ...
Query in this context means BW modelled queries:
- CDS based analytical queries ,
- Query modelled using BW modelling tools ( BWMT )
- Query modelled using BEx Query Designer

with several sample cases for CDS based queries and classical analytical queries.
