@al3xicon , we recently just did a similar one, only difference is it was for serialized inventory items.. Definitely scripting is needed. Problem we encountered is with the trigger. If you are using Advanced Bin Number Inventory management feature, it's not possible to load bin number/lot/serial number info by default before saving the transaction. Actually the use case for that client was to auto load the serial number information in the record page before saving the transaction ---- that's where we experienced the problem...Only solution was to entirely auto-create the inventory adjustment then In your case, You can probably create a scripted custom list page.. Somewhat similar to the bulk fulfill orders page. Only difference is you will manipulate the list of records to fulfill by sourcing the data through a custom search. The search will show the max qty. to fulfill for that SO, the preferred bin if with available quantity then the remaining to fulfill will be distributed to the rest of the bins with available quantity depending on what logic you want the distribution to be - on the bin quantity distribution part - that’s the tricky one and I’m not sure if it’s possible.
