Number sequence error when import prospects

Hi all,

I have tried to import prospects to smmBusRelTable. While I was trying to import data via excel add-in, I got the error " The number sequence CRM_2 does not allow the Prospect to be defined".

I have imported data which had number sequence fields many times before. But this time I couldn’t import the data because of this error. What should I do to solve this error?

Thanks a lot.

Have you tried creating the record manually, if yes what is the result?

Yes, I have tried and I created the records successfully.
