I am working on creating a monthly report for an inventory stuff, using a repeating group. But, here is a thing that I am struggling with for a while.
The structure is like this.
Date IN. OUT. Q’ty
For a product data type, I have data fields such as name, description… and current inventory.
As you can imagine, the problem I am facing is because the current inventory is the figure at the current date/time, I cannot use this figure for past dates.
For a certain date where there was IN or OUT, I am adding calculation to get the inventory q’ty for the previous day without problem, but when there is no IN or OUT, I need to set a date’s inventory by bringing the one of the next day’s but I don’t know how to call the next day’s inventory for a given date’s inventory.
Can anyone help with this?
