Transfer item tracking through source reservation codeunits
Description
Moving lot/serial tracking between document lines is a source-ownership operation, not a copy of visible tracking fields. Partial movement must retain the old source's remainder, destination units of measure, quantities to handle/invoice, status, sign, and any reservation counterpart. Repointing a "Reservation Entry" loses this coordination; inserting a "Tracking Specification" row alone does not book the destination's source tracking.
Best Practice
Reservation codeunits provide source-specific tracking workflows. For the tracking portion of blanket-sales-order or quote conversion to a sales order, "Sales Line-Reserve".TransferSaleLineToSalesLine takes the existing source line, prepared destination line, and quantity to transfer in base units. It delegates the source/status and quantity movement to "Create Reserv. Entry".TransferReservEntry.
The caller still owns document conversion and destination-line preparation; this method does not create a sales order. The source and destination must have compatible item, variant, location, and source identity. Purchases, transfers, assembly, and production have their own source-specific wrappers rather than sharing the sales conversion contract.
"Item Tracking Management".CopyItemTracking serves a different purpose: it creates Prospect copies, not a transfer of reservation ownership. That is valid for its intended copy workflow. Temporary Tracking Specification processing and persisted historical tracking specifications are also normal; the working/historic representation differs from the current source booking.

Anti Pattern
Direct rewrites of persistent "Reservation Entry" source type/subtype, ID, reference number, or quantities do not perform the source-line conversion or partial tracking-transfer workflow. Changing only "Quantity (Base)" and source keys can drop the remainder or leave the other tracking/reservation quantities attached to the wrong source.
A tracking copy cannot replace movement of an existing binding reservation. Legitimate Prospect copying, temporary tracking buffers, historical tracking reads, and source-specific engine calls serve distinct purposes and are not independent reservation transfers.
