Covers the insert record function, sift bucket numbers, the on init event for warehouse entries, and a feature key that is on by default. [Watch on YouTube](https://www.youtube.com/watch?v=QfOgUCXg94o) · Microsoft Dynamics 365 Business Central (YouTube) · 2024-10-08 · 5:21 · tier official · reviewed (checked by Opus) ## Overview The video explains how warehouse posting worked until now: one user could post at a time, with a register such as the warehouse register and then its entries, and entry numbers were found through locking. In BC25, multiple users can post at the same time, and entry numbers come from a number sequence. It then covers the changes developers need to know about. A new insert record function handles cases where someone has posted the old way with a lock table, and resets the number sequence if insertion conflicts. A semi-random sift bucket number lowers lock contention on sift indexes. Drill down filters on the register number, and an on init event lets extensions add logic before insertion. A feature key controls the behavior and can be turned off. ## Key points - Until now only one user could post warehouse entries at a time; BC25 allows multiple users to post concurrently. - Entry numbers are assigned through a number sequence instead of locking the table and finding the last entry. - Warehouse entries get a new field that records which warehouse register they belong to. - A new insert record function replaces simple inserts. It copes with old-style posting that still uses lock table and find last, and resets the number sequence if the insert does not succeed. - Warehouse entries get a semi-random sift bucket number between zero and four. This reduces the risk of sift index lock contention when two users post for the same item and location, but does not remove it. - Drill down from the register also filters on register number: either zero (entries from before version 25) or the register number. This was done to avoid expensive upgrades. - The on init event for warehouse entries runs after initialization and before insertion, and passes the entry number and the warehouse register. Extensions that use it to insert extra entries may need to implement the same pattern. ## Chapters - [0:00](https://www.youtube.com/watch?v=QfOgUCXg94o&t=0s) Introduction to warehouse posting - [0:28](https://www.youtube.com/watch?v=QfOgUCXg94o&t=28s) How warehouse posting works until now - [1:29](https://www.youtube.com/watch?v=QfOgUCXg94o&t=89s) New concurrent posting approach in BC25 - [2:23](https://www.youtube.com/watch?v=QfOgUCXg94o&t=143s) Insert record function and sift bucket handling - [3:22](https://www.youtube.com/watch?v=QfOgUCXg94o&t=202s) Drill down filtering and event hooks - [4:23](https://www.youtube.com/watch?v=QfOgUCXg94o&t=263s) Feature key and implementation considerations ## Features Every feature below: status not stated. | Feature | At | |---|---| | Concurrent warehouse entry posting | [1:29](https://www.youtube.com/watch?v=QfOgUCXg94o&t=89s) | | Number sequences for entry numbering | [1:29](https://www.youtube.com/watch?v=QfOgUCXg94o&t=89s) | | Insert record function | [2:23](https://www.youtube.com/watch?v=QfOgUCXg94o&t=143s) | | Sift bucket number assignment | [3:02](https://www.youtube.com/watch?v=QfOgUCXg94o&t=182s) | | On init event for warehouse entries | [4:03](https://www.youtube.com/watch?v=QfOgUCXg94o&t=243s) | | Concurrent posting feature key | [4:39](https://www.youtube.com/watch?v=QfOgUCXg94o&t=279s) | ## AL objects mentioned As heard in the captions.
