This blog is to explain our finding / solution to transport Hana Calculation views with dependent objects object with HTA – with classical transport.

Our main challenge was to move our Hana

Development using HTA as we decided to apply LSA++ concept on our Hana modelling, by using Harmonization layers, Transformation Layers and Data Access Layer.

Our Solution – still in change:


We used layers for this solution:

◈ Hana layer to retrieve all dependent objects for a calculation view, already used for us to have an understanding of all objects used in a model.
◈ BW ABAP layer for transport management and HTA


Hana layer:


To display dependency, following calculation view has been created:

This view is used, among others, to identify from master view all dependent views and tables


Semantic Layer:

Calculated column:

on AO projection: AO_DEPENDENT_OBJECT_NAME

Filter on AO Projection:
("PACKAGE_ID" ='$$Package_Name$$') AND ("OBJECT_NAME" ='$$CV_Name$$') AND ("OBJECT_SUFFIX" ='calculationview')

Filter on OD Projection:
("DEPENDENT_SCHEMA_NAME" ='_SYS_BIC') AND ("DEPENDENT_OBJECT_TYPE" ='VIEW')

Variables:

BW Layer:


External view based on Calculation view Dependency

We decided to use the standard program SCTS_HOTA_ORGANIZER and add an “automatic” selection of all dependent objects.

Standard program was not good enough for us as if a model consume 10 views from different package views need to be pick one by one.

Standard program has been duplicated and following change added (Lines where code has beed added is in the code bellow):

Transport is requested, all calculation views are now assign to transport and can be moved to QA

Following list is also provide with list of table need to be replicated.
