ELM: BP Grouping according to Origin of List

Hi,

My client needs to define the grouping of the BP created from external list according to the origin of the list in trx. CRMD_MKTLIST (Maintain Address List).

Example:

Origin A -> BP of the list are created with grouping ZAAA

Origin B -> BP of the list are created with grouping ZBBB.

How can a solve this problem?

Best regards,

Cristina
