Salesforce CPQ error "SBQQ.PriceRule__c failed" proposal total calculates to zero

TL;DR

Fix this in the Salesforce CPQ quote calculator by acting on the exact message first: open the failing price rule in Salesforce CPQ, set its evaluation order so it runs after the product rules that set quantity and list price, clear the calculated amount fields on the affected quote lines, and recalculate the quote. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

SBQQ.PriceRule__c failed

Use this when

• The operation in the Salesforce CPQ quote calculator fails with this exact message: SBQQ.PriceRule__c failed.
• The same failure repeats on retry with unchanged inputs.
• A proposal, quote or send is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in the Salesforce CPQ quote calculator, and copy the full message plus the proposal, quote or account involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: open the failing price rule in Salesforce CPQ, set its evaluation order so it runs after the product rules that set quantity and list price, clear the calculated amount fields on the affected quote lines, and recalculate the quote. Verify: the recalculated quote total equals the sum of the line net amounts and the calculation log shows the price rule as evaluated.
3. Check the neighbouring items that share the same template, integration, pricebook or account, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Compare the result against the source system in the Salesforce CPQ quote calculator so a silent partial success is caught before sign off. Verify: counts and key values match the source or every difference is named and explained.
5. Rerun the original operation in the Salesforce CPQ quote calculator on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

the price rule ran before its input fields were populated, so it evaluated against empty values and wrote zero back as the quote total.

The how-to phrasing for the same failure in the Salesforce CPQ quote calculator. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

Troubleshooting this failure in the Salesforce CPQ quote calculator

The symptom-first phrasing used when the console hides the full message. Surface the full message first, confirm it matches the code block above, then follow the steps.

Compatibility: the Salesforce CPQ quote calculator at current versions, plus the platform API or console the query names; no extra tooling beyond the source system access needed to verify counts.
