BIP-BRM integration with multithread.

Hi,

We have executed pin_inv_doc_gen for BIP-BRM integration with multithread.

while executing the API,it returns a correct reports  when running it with only one thread/connection .

However, some the report itself have incorrect content when using multi threads, for example we send report for invoice1 and invoce 2 , but we receive invoce 1 two times.

thanks,
