Autoinvoice import program is completing with error with error msg- Error calling raapic()

Autoinvoice import program in AR is going into error with error msg- Error calling raapic(). We did many hits and trial but still nothing happening.

We tried to import the same data in test instance. When we imported only line level data, we didn't receive this error and program was successful. But when we imported the line distribution level data and ran the autoinvoice import program it failed again with same error.

Can you help with some solution.
