ASN Generation in iSupplier portal

Hello Oracle Friends,

Can we generate ASNs automatically with Specific sequence and unique number across Supplier/Supplier sites in iSupplier Portal.?

Example: We would like to Generate unique ASNs across supplier/Supplier site with Specified sequence like as ASNYYYDDMMHHMM or Any other sequence

ASN is first fixed three characters of the ASN shipment number

YYYYDDMM is the next 8 character constitute of Year, Month and Date

HHMM is the next 4 character numbers constitute of Hours and Minutes

HH is the time in 24 Hrs.

Thanks
