is there a report in WM that tells when was the last time a bin was counted based on the ABC indicator. like A means 90 days (a bin that was counted more than 90 days agao), similarly for B for 120 days and etc etc. Just looking for a report that says, here is hte list of WM biuns that you have to count.
You can use LX03 transaction, by default you will not have last inventory count date over there, select those fields from 'current layout" tab. Here you will not get the distinction as per ABC, but you can see "PZ" which is for continuous inventory.
You can use transaction LX16 for carrying out continuous inventory.
