API Sales_Order batch huge quantity of line items ... process crashes?

[lmonteroquero]

Hi, experts.. 

I´m trying in $batch processing post a new sales orders containing 10,000 line items.. via Postman, I press button "sending" on Postman,  and still for all the time with message "Loading" for an hour .. nothing appears to happen or processing, and I get time out message after one hour time. 

Attached batch file I´m trying to process.. 

Any suggestion? anyone knows why ?

Thanks for helping

Hi Luis

This is a massive payload for S/4HC to try and process at one time. Can you try breaking the data down into smaller chunks and seeing what works for you? For example, are you able to post 100 line items at a time? I think I've read somewhere before that ~50 is recommended changeset increment for some services --not sure what it is for SalesOrder but I suspect 10,000 is way too high for a real time processing.

Thanks,

Marty
