Error message - 15157293 : The resource or resource instance specified does not exist on the job /15

Hello,

When we query in Pending Jobs and Schedule form with job no. we receive error message as below:

15157382 : System cannot add resource because requested resource_seq_num has already existed or less than or equal to 0.

15157293 : The resource or resource instance specified does not exist on the job.

Would be great help if someone can explain the probable cause and soution.

Thanks,

Ajeet M
