There are many way to import data from SQL Server into SAP BW:

(1) SAP BW DB Connect

With DB Connect, you can load data from a database system that is supported by SAP, by

linking a database to the BW as a source system, thereby creating a direct point of access to external relational database management systems (RDBMS).

Making metadata known to BW by generating a DataSource.

Discussion

While searching for this issue, using SSIS to achieve that is not recommended because it may encounter some incompatibility issue, they recommended to use SAP BW standard anyDB source system or SAP BO Data services.

Issues example:

On the other hand, SSIS guarantee the ease of use and there is thousands of topics and references for this technologies which will help you to achieve your goal faster than other technologies.

I guess the easiest way would be to use an ETL tool to extract data from MSSQL and insert into BW; specifically Microsoft's Integration Services (SSIS), which you likely already have with your SQL Server license.

SSIS is a visual tool specifically designed for ETL scenarios like what you described, and is easy to get started with, I'm guessing that this tutorial covers 90% of what you'll need to do.

However, you should also investigate if your license allows you to use the SSIS connector for SAP BW and test if it is a viable option to simplify writing to BW, as writing directly to BW's tables may not be an option (e.g. because of licensing restrictions and/or technical impact due to directly manipulating a closed system's database).
