It is acceptable to do RSCH in stand alone and obviously you will get a drastic count report if you do not confirm. It is actullay best practice to do RSCH in stand alone if the numbers don't drop for the task list. My advise is this: when it comes to the drastic count report, if you are not sure of a high dollar item's OH due to unpushed freight, backstock, zone whatever...enter the OH (to get it off the report) and keep an eye on that item. I wait 5 days on items I am unsure on. If the OH is the same by then I adjust it. You have 6 days before the item falls off the report and is counted as not worked. I exf areas I get hits on if it is a recently set planogram. I have yet to screw up accumulator.
you should talk to your ptl
they should be shooting exf's and research on areas they recently set
would solve alot of your problems and save you some time of having to figure out what's going on in certain areas, you also can't be everywhere in the store on any given day to fix problems that they should have taken care of.
