Database Techniques for SAP ABAP best practices

It is inevitable for a business application development platform like ABAP to become one of the widely used and preferred software. The advanced features and performance techniques available in ABAP make it one of the dominant application programming platforms to create a wide range of business applications. So far, the application programming and development platform remained as the most preferred development environment by majority of the SAP application developers. While training yourself on SAP ABAP, following database techniques would help you to create applications that are improved with their end-user experience and overall performance.

Creating secondary index

While the primary index is created automatically with the primary keys that are defined with the database, you can improve the performance by using secondary index instead of primary index. Unlike primary index, this index is not created automatically but reduces the scanning time drastically and improves the overall performance.

Avoid unnecessary inclusion of entire record everywhere

On most occasions, the record is selected entirely to use one or few elements. This would cause indexing of all the elements and unnecessary network loads. Instead of that, use ‘where’ clause with the select statements which would point to the respective value or elements which would let the database system to index only the appropriate values.

Fetch data to internal table than appending it to a loop

SELECT INTO [TABLE] statement is always the best way to retrieve data instead of using SELECT in LOOP statement. The reason is that, when the data is fetched to internal table, it saves the system from database hit which ends up in high network traffic.

For single retrievals, use SELECT SINGLE with ‘Where’ clause in place

As for as using the SELECT 8… END to access the values in the database table will engage in repeated network loads for each value retrieved to the table. Thus, using SELECT SINGLE with the respective where clause could avoid that unnecessary expenditure of the resource.

There are many such techniques and key tips to speed-up the performance of the applications created using SAP ABAP programming platform.

Hence, the point is very clear that digging deep into logic and analyzing how each statement and its attribute works will help finding an alternative and efficient statement to replace them. This could help you to reap the benefit of high performance and excellent independency during your SAP ABAP database functions.
