Hi,

I want function module to get the plantwise invoices.

Currently i want to write query on VBRK for invoices and for plant details i need to write query on VBRP.

For large data it takes more time.

So can anybody tell me regarding this?

Regards,

Deepak.

Check for this FM WLF_INVOICE_CHECK_WERKS if it suits your requirement.

Thanks

Hi...

Following are some performance tuning conditions....

and better to go for for all entries method.. because it links the tables at application layer level..

Use Select Single when only one row is expected

Use Select Where rather than Selectu2026Check

Use Select with aggregate functions (SUM, MAX, MINu2026)

Use a View instead of nested Selects

Use Select column specific instead of select * for few fields

Use Selectu2026Into Table rather than Select...Move Corru2026Apend

Use Join extension with Select if possible

Use special operators (CO, CA, CS) rather than code your own

Use Delete Adjacent Duplicates rather than manual processing

Specify key fields for Readu2026Binary Search

Use Loop At Where rather than Loop Atu2026Check

Copy Internal Tables with TAB_DEST() = TAB_SRC()

Specify the sort key as restrictively as possible

Use Append To, Insert Into, Collect Into rather than Move

Compare tables with If Tab1() = Tab2()u2026

Use Delete ITAB Whereu2026 instead of Loop At ITAB Whereu2026Delete..

Use Case statements instead of If-constructions

Use Call Functions wisely, Performs use less memory

Use While instead of Do Exit

Use Type I for Indices

Keep Occurs clause realistic or use 0

Use COMMIT WORK as appropriate to free the Data Base and preserve work

Avoid:

Using Shift inside a While-loop

Leaving unneeded declarations in your program

Using Move-corresponding for just a few fields

Excessive nested includes within function calls

Using DB field names if the value will be changed

Using Occurs clause if only the header is needed

All the best!!

Thanks,

Naveen Inuganti.
