is there any filter in saved search which i can use to get quantity on hand for a particular month

Sounds like you'd either need to use two separate filters, one for month and the other for quantity. Or use a summarized saved search, grouping by month.

There is no date filter on item saved search. Just wondering what do you mean by use a summarized saved search, grouping by month.

Ah didn't realize you were looking at an Item saved search. So you're looking for a historical amount of the quantity on hand of items? I know NetSuite isn't strong in being able to provide historical changes like that, but have you looked at System Notes fields in the saved search?

Item record system notes does not track quantity on hand changes, so it is not possible to get quantity on hand for a particular month in saved search

Too bad. I guess your only recourse is a scheduled script that runs monthly, which runs a saved search to get the current quantity on hand and then stores the value with a join to the item into a custom record.

yeah. I am thinking something similar
