CREMAS Data is not Relicating Automatically

Dear MDG Experts,

I am trying to send Vendor data to ECC system, all the ALE and DRF set up is done. IDOC was generating automatically with change pointers.

Recently we have changed Number Ranges and CVI integration, nut sure because of this cong, now auto generation of IDOC is not happening.

Did any one faced the same issue? is it because of changes of CVI integration ?

Any idea really appreciated.

Thanks and Regards,

Preetham
