title: "#9688 [main] Hidden breaking change and instability on sales/purchase line insert"
summary: Makes the v28 check that blocks inserting sales and purchase lines without an existing header more reliable, since it raised false-positive errors. The suppress switch is renamed, a SetSuppress...ExistsVerification procedure is added, the header is checked with an explicit Get, and temporary lines skip the check.

# #9688 [main] Hidden breaking change and instability on sales/purchase line insert

> Makes the v28 check that blocks inserting sales and purchase lines without an existing header more reliable, since it raised false-positive errors. The suppress switch is renamed, a SetSuppress...ExistsVerification procedure is added, the header is checked with an explicit Get, and temporary lines skip the check.

[Pull request](https://github.com/microsoft/BCApps/pull/9688) · merged into `main` (BC30) on 2026-08-04 by JakovljevicDusan · 28 files (+1279 -287), 26 AL · fix · tier official · reviewed (checked by Opus)

## What changed

- Sales Line variable HasSalesHeader renamed to SuppressSalesHeaderExistsVerification to show it is a skip switch
- New SetSuppressSalesHeaderExistsVerification() so the switch can be set without SetSalesHeader()/ClearSalesHeader()
- VerifySalesHeaderExists() now uses an explicit SalesHeader.Get() instead of GetSalesHeader()
- Verification is skipped for temporary lines; OnBeforeGetSalesHeader keeps its HasSalesHeader parameter name
- Purchase Line receives the symmetrical changes; tests updated in SCM Orders VI
- Behaviour changes for users or extensions.

## AL objects touched

- [Table 39 "Purchase Line"](../../objects/table/39.md), Base Application: modified
- [Table 37 "Sales Line"](../../objects/table/37.md), Base Application: modified
- `src/Layers/BE/BaseApp/Sales/Document/SalesLine.Table.al`: modified, not in the BC30 snapshot
