Oh, and another thing - recheck the item merge for the current week every single day of that week. Stuff may come in off the truck later in the week that will be a casepack of a DPCI that didn't have casepack locations on the report. This casepack will no doubt still have the old DPCI on it, so you'll have to go through the merge motions on it. If you don't, come next week, your previous-week report will be less than 100%, since old DPCIs came in after you did the merge.
If you are talking about the list that populates in an Excel worksheet, that has never worked for me. I always had to pull up the report under store reports on workbench.
The excel sheet is gone, the link under Logistics just sends you to store reports now, where the new-style item merge worksheet is. The excel spreadsheet was great in principle, but the goddamn thing never worked 75% of the time. I'd do everything right, then hit the find backroom locations button, and it'd immediately crash with an error letting you either stop the process, or debug the code - and the relevant code looked fine, especially since redoing the sheet on another computer would work. It was just a damn hassle having to roll the dice like that.
What I was talking about was the item's UPC still scanning under STO/SUBT/LOCU, etc. under the old DPCI instead of the new DPCI, meaning I have to go to the receiving or signing computer to store apps to do the UPC/DPCI Maintenance function to retie the DPCIs properly. Every week it's 8-12 DPCIs that I have to do this for, and it's almost exclusively HB01/HB02/PHAR/COSM. Except for this week, which was great, with none needing to be manually retied in the computer.
You can relocate items using LOCU.
Some logistics ETLs don't want people to update using LOCU. Some of them want you to erase the location using LOCU, but then put everything back into the location using STO so that they have a name they can look up and yell at on the Backroom Detail Report if something is wrong. LOCU doesn't show your name on the Detail Report.
