To check batch history:
Click Stock Parts then click F5 on the part.
In the top right there is a drop down box labelled 'View'. That has two options, 'Live Batch Records Only' and 'All Batch Records.' If this is greyed out, the other option is not available (for example if there are no live batches).
By selecting the batch required then the transactions are shown in the bottom box, showing receipt, movement and issue of the stock. Using this, the current position of the stock can be seen.
