The finance team wants to create a sub-account for the Inventory General Ledger account.

In Workday Adaptive Planning, when a sub-account (child account) is created beneath an existing General Ledger account, the system converts the parent account into a rollup account. As part of this structural transformation, all existing data and any formulas that were previously stored in the parent Inventory account are automatically migrated to the newly created child account. The parent then becomes a rollup that aggregates the values of its children. This behavior ensures no data loss during model restructuring. The rationale is that rollup accounts do not hold direct data — only leaf accounts (bottom-level accounts without children) can contain input values or formulas. Therefore, the system must relocate the data to maintain model integrity. Administrators should be aware of this behavior before creating sub-accounts in live environments, as it directly affects reporting and formula references. Existing reports may need to be updated to reflect the new account reference. Reference: Workday Adaptive Planning — Chart of Accounts, Account Hierarchy, Sub-Account Creation Behavior.
