SAP EWM is the warehouse module of SAP. Every pick, put-away and count is recorded there as a warehouse task, and what sits on each shelf is recorded as stock. Odyssey does not connect to SAP directly — you export a report from SAP to Excel and drop the file here.

Two warehouses are kept strictly apart and never combined: S099 is production, where the picking happens, and D099 is development, where stock is held. In the file itself they appear as the SAP owner codes BPS99 and BPSDEV, which is how Odyssey works out where a file belongs without asking you.

Nothing is ever overwritten. Re-importing a month creates a new revision and the previous one stays queryable, so last month's report still produces last month's numbers.

An audit compares what is physically on a shelf with what the system says is there. Odyssey keeps that evidence completely separate from the stock export: no audit ever changes the material data. What it produces is a list of differences and a named person's decision about each one.

Opening an audit freezes the sheet. Pick a section — an aisle, a rack, a single bin, a part, everything over a year old — and the expected quantities for it are copied at that instant. Importing a new stock export the next day does not change what your count is being compared against, which is what lets a finding from last month still be checked this month.

Blind counting is on by default. The system quantity stays hidden until you enter a count. Somebody who can see "10" and half-counts nine will write ten; hiding it is the standard control against exactly that, and you can switch it off from the count sheet if you need to recheck a line.

Differences become SAP postings. Approved quantity differences are listed as inventory-difference movements: 711 when the count found less than the system holds, so the difference leaves stock, and 712 when it found more, so the difference enters stock. Direction lives in the movement type, so the quantity on the list is always unsigned. If your site maps 711 and 712 the other way round, correct it before posting — a difference posted the wrong way moves the stock twice in the wrong direction.

A relocation gets no movement type at all. Stock found in the wrong bin was never lost or gained; it is a bin transfer. Posting it as a difference would write off stock that is sitting right there and then receive it back.

Accuracy is always reported next to coverage. Ninety-nine percent accuracy across two percent of the warehouse tells you almost nothing about the other ninety-eight, so the dashboard shows both and the assistant is required to quote both.

Counted on paper or with a scanner? Drop the sheet onto the count sheet tab. Columns are matched by meaning rather than exact spelling, and any row that could belong to more than one line is shown to you rather than applied — a count written against the wrong line invents a difference in one place and hides one in another.
