how to fix proposal error volume discount tier applied twice in pricing table fails

TL;DR

Fix this in the pricing table by acting on the exact message first: find the volume tier rule in the pricing table, remove the duplicate application by keeping the tier discount on the line rule only and clearing it from the table level rule, then 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.

Use this when

• The operation in the pricing table fails with this exact message: proposal error volume discount tier applied twice in pricing table.
• 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 pricing table, 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: find the volume tier rule in the pricing table, remove the duplicate application by keeping the tier discount on the line rule only and clearing it from the table level rule, then recalculate the quote. Verify: each line shows the tier discount applied once and the table total matches a hand check at the tier rate.
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 pricing table 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 pricing table 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 same tier discount was configured at both line level and table level, so the engine multiplied it in twice.

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

Troubleshooting this failure in the pricing table

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 pricing table at current versions, plus the platform API or console the query names; no extra tooling beyond the source system access needed to verify counts.
