We have been seeing this issue with a few of our customers who are running SAP Business One 9.1 PL7.
Enter an Inventory Counting document for batch-managed items.
Copy to an Inventory Posting
Open the Batch Number Selection Window
When the Batch Number selection comes up, the full quantity of all of the available batches for each item are already selected to issue out no matter what the actual count variance is. (See attached image)
To get around this, the customer has to move the batches back to the left side (Available Batches section) and then select the batches that are actually going out. This also happens if you should be bringing more of the item into stock, so in that case you need to unselect all batches and then create the new batch like you normally would.
This doesn't happen if you create the Inventory Posting manually instead of copying from an Inventory Counting document.
I haven't been able to find any SAP Notes about this issue, so I don't know if it is fixed in a later PL or if we are doing something wrong on our end.
Any help would be appreciated.
