Complex Customer Hierarchy

[PEPS29]

Our company is transitioning from three separate CRMs systems to SAP. Currently, we have duplicate customer records across these CRMs because each system is used for different product ranges.

The initial plan is to maintain these duplicate/triplicate customer accounts in SAP, as each account, though representing the same entity, often has different payers, delivery addresses, and assigned sales representatives. However, we're exploring if a more structured approach is possible.

Example of our customer structure: 

We sell products to various schools under the New York City Department of Education through different contracts. In our CRMs, each school isn't treated as a single entity; instead, different departments within the same school are handled as separate entities. 

For example:

1. The science department of a high school purchases lab equipment and is billed separately.
2. The athletic department of the same high school also buys from us but is treated as a distinct entity.

Ideally, we'd like to structure our customer hierarchy in SAP as follows:

1. Parent Account: New York City Department of Education
2. Child Accounts: Individual Schools
3. Sub-Child Accounts: Departments within each school (e.g., Science Department, Athletic Department)

Questions are:

1. Is it possible to create this hierarchical structure in SAP? Who in the example would be created as a business partner? In my eyes the department of education and each school would be Business partners, then each department would be created as a child of each school?
2. If that's true, can each child and sub-child account have its own:
• Sales representative
• Payer
• Delivery address
• Other unique attributes
