Preface – This post is part of the SAP Multi-Target Application (MTA)  series.

Introduction

A Multi-Target Application (SAP MTA) is a package comprised of multiple libraries, application and resource modules. These have been created using different technologies and deployed to different runtimes but have a common life-cycle. You can bundle different modules together, describe them along with their inter-dependencies to other modules, services, and interfaces, and package them in a Multi-Target Application(MTA) .

Technologies and Tools Involved in SAP MTA

Default Project Layouts

Note: */ denotes a folder and /* signifies a file

Prerequisites and Restrictions

We need to consider the following limits for the SAP MTA deployment on SAP Cloud Foundry deploy service:

• Maximum size of the MTA archive: 4 GB
• Maximum size of MTA module content: 4 GB
• Maximum size of MTA resource content: 1 GB
• Maximum size of MTA descriptors (mtad.yaml and MANIFEST.MF): 1 MB

Best Practises related to SAP MTA:

• The MTA descriptor is built in the YAML format and has strict syntax requirements. You can edit the descriptor in the text-based code editor, but it is recommend to use the visual MTA editor because it provides input validation.
• Use the HTML5 Application Repository in a Multitarget Application as it enables to update the HTML5 applications without restarting the application router in the Cloud Foundry environment.
