When we schedule mass billing by EA26, error gets logged for few installations in application log as below
Internal error in form check_input (function module isu_output_ioper_process)
Billing was terminated for installation &
When we do manual bill by EASIBI, then it runs successfully. Even when we run that batch job again, the failed cases of installations are also gets done.
I am not able to track the problem why this error gets generated. If its data issue then it should be coming everytime. Surprisingly it comes only once and that also in batch job.
Please suggest on this.
