API Reference > imodeljs-backend > iModels > ConcurrencyControl > endBulkMode endBulkMode Method Beta Call this when in bulk mode and before calling BriefcaseDb.saveChanges. This function sends a single request to the iModel server for all locks and codes that are required for the changes that you have made since calling startBulkMode. If the request fails, then you must call BriefcaseDb.abandonChanges. Bulk mode is a reasonable choice only when you know there is no chance of conflicts. endBulkMode(rqctx: AuthorizedClientRequestContext): Promise<void> Parameter Type Description rqctx AuthorizedClientRequestContext Returns - Promise<void> Defined in core/backend/src/ConcurrencyControl.ts Line 99 Last Updated: 29 November, 2022
