Parallel cursor is the technique to increase the performance of the program, when there are nested loops. For example if we use nested select in our program instead of For all entries addition, then definitely performance going down. In the same way the if we use nested loops in the program it will also leads to down the performance. For example:

What is parallel cursor in ABAP?
Parallel cursor is concept of improving the performance of ABAP program when there are nested of loop. In above video you can find ABAP code for parallel cursor.
What is the use of parallel cursor in Python?
Parallel cursor is the technique to increase the performance of the program, when there are nested loops. For example if we use nested select in our program instead of For all entries addition, then definitely performance going down. In the same way the if we use nested loops in the program it will also leads to down the performance. For example:
How can parallel cursor improve the performance of a report?
With multiple techniques available to improve the performance of a report or any FM/Class Method for eg, Parallel Cursor plays a key role. Here’s why. In ABAP, conventionally we use the LOOP statement using the ‘WHERE’ clause. When there are nested loops, the ‘WHERE’ clause would scan the entire table to find the matching key fields.
With multiple techniques available to improve the performance of a report or any FM/Class Method for eg, Parallel Cursor plays a key role. Here’s why. … In the program result below you can see how Parallel Cursor performs when compared to normal nested Loops. The time taken by each method is displayed in microseconds.
What is parallel cursor?
What Is Parallel Cursor Concept What Is Parallel Cursor Concept Parallel cursor is the technique to increase the performance of the program, when there are nested loops. For example if we use nested select in our program instead of For all entries addition, then definitely performance going down.
Why parallel cursor is important for ABAP development?
As an ABAP Developer, there are times when you might face a scenario where performance improvement is required when working on either existing reports or while developing a new one from scratch. With multiple techniques available to improve the performance of a report or any FM/Class Method for eg, Parallel Cursor plays a key role. Here’s why.
How to loop on the second table in parallel cursor?
In parallel cursor, we first try to see if there is any entry exist in the second table inside the LOOP construct of first table. We use the READ .. WITH KEY .. BINARY SEARCH to check if the entry exist in the second table. We use this record number SY-TABIX to LOOP on the second table using LOOP .. FROM index.
How can the client make its interfacing with the cursor faster?
The client can make its interfacing with the cursor faster using two methods. Bulk binding. Bulk fetching. This reduces the amount of times the client needs to call the cursor for transferring data. Instead of passing (or fetching) a 100 values one value at a time, this can be done using a single call and bulk binding/fetching a 100 values.
