SAS Web services payload size - http 413 error

Question

I have developed a stored process to receive an XML file as a response to a web service call and deployed it as a web service - something similar to the example here.

It is successful and working fine in receiving an XML file which is of ~100KB but failing to receive similar file which is about 3MB. The other system sending the response seems to throw the below error 

HTTP Response Code 413 for 'https://mystoredprocessURL'. I understand that this is related payload too large in size.

Could you suggest me how to configure the length of payload size that has to be received so that the stored process can receive a larger file. Tried to research but could not find anything relevant.

Answer 1

my first idea. I hope this helps, but that's just a hint:

SAS SMC-->plug-ins tab-->Application manager-->configuration manager-->
SAS Application infrastucture-->BI web services for java 9.4-->WebServiceMaker
-->Settings tab-->Attachemnt optimized threshold block. 
Maybe the default size is 2048.
