taGetPaymentNumber eConnet Error 3413: Unable to increment next document number from Document Type Setup after 1000 attempts (RM40401)

Hi,

I am using eConnect to generate big cash receipt transaction batch in GP2015. However sometimes I get error as below. Not all the time.

Please advise what might cause the next document number for cash receipt not getting updated in RM40401.

What if user forgot to close the cash receipt window. Will the next cash receipt number gets occupied in setup and can't get updated?

Exception message:

Source Procedure: taGetPaymentNumber

Error Number: 3413

Error Description: Unable to increment next document number from Document Type Setup after 1000 attempts (RM40401)

Stack Trace:

Thanks in advance!
