Hi Praveen,
1)
Go to SNRO-> object-LOY_CRD_ID, create the number range ID and interval.
2) Go to the Number ranges.path: SPRO->Customer Relationship Management->Marketing->Loyalty Management->Basic Settings->Define Number Ranges
| Application | Object | Number Range ID |
|---|---|---|
| MSH Membership | CARD Card | LOY_CRD_ID |
Assign the above defined NR interval here.
This will solve your problem.
Regards
Pramod
