Sir can't thank you enough for such a precise breakdown of parallel cursor technique.
Before I used to not understand nested Loops and all stuff, now you made me understand the concept pretty well. ❤🙏

[Rajasekharabap]

U are god sir thank u
Now clearly understood when we go for read table, nestedloops, parellel cursor

[venkateshbathula-ubpd]

Hi Sir Please tell about the parallel processing concept
sir I have one query can we do a parallel processing technique for submitting reports by using job open and job close if you have any info on that please share any blogs

[mohammed]

Crystal clear explanation. Thank you so much sir

[rajatkushwaha]

Hi Rahul, i think total iteration should be 11 as we are also hitting exit statement three times so loop will run 8 times for the data record and 3 times for exit statement. Correct me if i'm wrong.

[poojamamadapur]

hi Sir, where and how is Binary search done as we are using it in the read statement but is the binary search really done? it seems like a linear search for me. Please clarify

[TheAnsh]

sorting of internal table based on order line table is obligatory for this logic inspite of not using binary search?

[vikharkhan]

Great explaination. I have a question. Does the sy-tabix returns current loop iteration or returns the index number from where data transferred to work area?

[akshaytaralkar]

Hi rahul can instead of LV_INDEX can we directly use SY-TABIX in inner loop.

[NagabothuRajasekhar]

Hi sir i have doubt
1 i have used binary search but not applied sorting will binary search work can i display record?
2 i have sorted in descending order and used binary search
Can i display record in this case?
In interview asked can u please clarify?

[lathamalempati]

Hi sir, parellel cursor method means
Using some more logic like using read table and sorting the table to improve the performance right sir?

[grzewicz]

Hi. Thanks for great explanation. From my understanding, each loop has its own sy-tabix value, right? When these values are reseted? When program finishes?

[lathamalempati]

Sir do we have to sort only 2nd internal table?

[mohammednabeel]

Hello Sir, how does it make difference in performance if we sort both tables based on key first and then use nested loops with where condition using key field without using parallel cursor?

[sireeshaande]

Hi, can we use parallel cursors for more than 2 loops..?

[AliAsim-ksbr]

Hi Rahul Do you give online training on Abap?

[yuvrajkarwar]

Sirji, what if key columns are not in order?

[charan]

In the parallel curser also we have do the bug analysis like if we add new record in header table. It was not reflecting in the output. You have explained about bug analysis for the normal process. Do We have to do the same process for the parallel cursor?
