Unit of Work (UOW) Support for Cart APIs
The Unit of Work (UOW) is a design pattern that reduces repetitive code when implementing transaction management and the coding overheads of adhering to DML bulkification.
The UOWMode = true setting in CPQ configuration enables UOW performance enhancements that save data manipulation language (DML) and Salesforce Object Query Language (SOQL) statements when making Cart-Based API calls.
If UOWMode is set to false, these performance enhancements aren’t enabled. Starting with CME Summer '22, UOWMode = false is discontinued and not supported. See CPQ Configuration Settings Reference.
Here’s the list of Cart APIs that support UOW mode:
- postCartsItems
- putCartsItems
- deleteCartsItems
- getCartsItems
- postCartsPromoItems
- getExpandedItems
- replaceOffers
- deleteAppliedPromoItems
- cloneItems
- runCartValidation
- compareOffers
- getCartsItemsById
- getAllAssets
CART APIs with UOW support must be chained only with UOW-supported APIs. A problem occurs if you string a UOW-supported API with a non-supported UOW API in the same Salesforce execution context.
