Stocktake Issue

Hi there,

I am looking at doing a stocktake because I have some stock discrepancies. This is the only plugin I could find that had a stocktake function. I have tried a few times to perform the stocktake but I always get an error message when I try to finalise it.

Here is a link to an image of the message: https://drive.google.com/file/d/1sh1C_mjAk9kND6u5KdfjwlyUNZ7RuQE1/view?usp=share_link

Does anyone know how to resolve this issue?

Thanks, Ben
