When transitioning an AWS Partner Generated Billing (PGB) customer from a **Consolidated** billing block to a **Full Family** billing block, a duplication of credits (such as AWS Bedrock credits) may appear in the customer's Cost History after a billing rerun.
Symptoms
- General Credits in Cost History show approximately double the expected amount.
- Detailed drilldown reveals the original pinned credits are present alongside numerous unexpected credit line items.
- The duplication persists even if no Solution Provider Program (SPP) discounts are visible in the partner tenant.
This issue occurs because the **Full Family** configuration automatically passes down credits from the payer level. If credits were previously applied via the **Credit Pinning** tool while the customer was under a **Consolidated** billing block, those pinned credits remain in the system. When a rerun is triggered under the new Full Family block, the system applies both the passed-down credits and the manually pinned credits, resulting in a duplication.
To resolve the duplication, the manually pinned credits must be removed before executing a final billing rerun. The Full Family billing block will naturally account for these credits without the need for manual pinning. Please open a support ticket for assistance.
