Abstract: In an example embodiment, when a user creates a consignment issue item for a given product in a sales order, the system will reserve/temporarily allocate the available quantity in consignment stock. A synchronous call to lock the inventor makes a tentative update to the inventory stock on the quantity required for the request product on the created issue item. This update is tentative because the locked quantity should be released if the user decides not to save the document, but it also should be locked so that it is not available to another user who is also trying to create an issue item in a different sales order document for the same product in a parallel session. The allocation may also change several times before saving the document by additional synchronous calls that again update the tentative allocations. When the user finally decides the final state of the issue item, it asynchronously sends either a confirmation or compensate message based on whether the document was saved or not saved.
