help me figure out why the indicator Shipped in orders is buggy. The system allows double debiting

Hello, the problem with the specified orders and all the others has now been fixed.

the problem repeats, here is the order where there are 5 goods, 2 are written off, after correcting the field shipped, I added 2, but the fifth one was marked as Shipped and is not written off

item 37681
after the errors were corrected, I selected 3 not written off products and did the action to write off, but they were not written off, and the product 37681 appeared Shipped 1, I selected the remaining 2 and managed to write them off on the second attempt, but this product has Shipped 1, but it is out of stock process is not written off.

I created a new topic where I described a global problem in this regard, at least it exists in my CRM and it has not been solved for a long time, periodically arising it causes damage and we can only identify what we noticed, when analyzing all the BPs for a certain period, managers found more BP with errors (I solved them myself), but according to the principle of operation of financial and warehouse accounting, the system allows such errors to occur and they are often hidden. with a large number of operations, they are extremely difficult to identify and require a lot of time

Enabled you safe mysql mode
now if the system fails to insert a record when writing off or posting (when the line is occupied by another process) - you will see an error and such problems should go away

those. the procedure will not work if there is an error and it will be necessary to repeat it simply? How does protection come out of duplication of actions?

this is a very painful topic due to the fact that if you do not find such errors, it leads to "re-sorting" and shortages of goods, you have to spend a lot of time on the proceedings
