How exclusion works during a count
When a count turns up a quantity you do not trust, you can hold that item back from posting by keeping it off the count sheet. In Advanced Inventory Count, only the items that appear on a count sheet are reconciled and copied to the journals. If an item is not on a sheet, the count process leaves it alone and no adjustment is created for it.
Advanced Inventory Count builds its adjustments from the lines on your count sheets. The reconciliation routines compare the counted quantity on each line against the expected quantity, then copy only the differences to the standard Business Central journals. Removing a line, or never adding it in the first place, takes that item out of scope. The item keeps its current on hand quantity in Business Central, and nothing posts against it until you decide what to do. This is the safe way to set aside a suspect figure while you walk the floor, check receiving paperwork, or confirm a bin.
Investigating before you adjust
Because items left off the sheets are never touched, you can finish and post the rest of the count without waiting on the one item under review. After you understand the variance, you can add the item back to a sheet, enter the corrected quantity, and reconcile it on its own. If the item is on a sheet but you simply have not entered a value yet, the line stays flagged as uncounted, which is another way to prevent an unverified figure from posting.
Keeping an audit trail
For discrepancies you do want to recheck rather than drop, the recount tools give you a more formal path. You can flag a line for recount, which locks the original count quantity so it cannot be edited and records the recounted value separately. That preserves the original figure, the recount figure, and who entered each, which is useful when auditors ask you to spot check specific items. Excluding an item and recounting an item are complementary tools, one for setting something aside entirely and one for documenting a second look.
Related Tools
Advanced Inventory Count manages count sheets, reconciliation, and the transfer of differences to the Business Central journals, and it is where you control which items are in or out of scope for a given count. Warehouse Insight extends the same count to handheld devices, so the decision to count or skip an item can be made on the warehouse floor while scanning.
Conclusion
The simplest way to investigate a discrepancy before you adjust is to keep the item off the count sheet, since Advanced Inventory Count only posts the items it can see. Add the item back once you have answered your questions, or use a recount sheet when you want a documented second count rather than an exclusion.
