+# Carry out requisition actions through the standard workflow
+
+## Description
+
+A requisition/planning line is a pending change to a supply/demand network, not just a template for a purchase line. Carry-out interprets New, change-quantity, reschedule, and cancel actions, preserves referenced supply and planning flexibility, and moves reservation/tracking ownership before finalizing the proposal. Creating a plausible purchase order and deleting the requisition line can leave new supply unrelated to the demand that caused it.
+
+## Best Practice
+
+For requisition batch carry-out, initialize `"Req. Wksh.-Make Order"` with `Set` and invoke `CarryOutBatchAction` on the intended accepted lines. Supply the order/posting/receipt defaults separately from the ending-order-date cutoff, and preserve the selected worksheet/batch/line filters. A plain `Run` or a single order-line insertion helper is not a replacement for this batch initialization and finalization.
+
+Use the standard `"Carry Out Action"` dispatch for broader planning output and its configured purchase, transfer, assembly, or manufacturing choices. Do not turn every action into a new purchase order, bypass source-specific reservation transfer, or delete proposals before the owning workflow has completed their supply change.
+
+Ordinary manual purchase creation that does not consume planning output is outside this rule. Users may reject or delete unwanted proposals without creating supply; temporary planning simulations, pre-carry-out enrichment, and engine-owned cleanup are also legitimate. `Delete(true)` on a requisition line is not intrinsically a defect.
+
+The samples select an existing accepted New/Purchase item proposal with sales-demand context. Dates are explicit, the source selection remains bounded, and the clean sample leaves order creation and reservation handoff to the standard workflow; it is not a complete planning-run generator.
+
+## Anti Pattern
+
+Report code that consumes accepted persistent `"Requisition Line"` action messages, manually creates or changes supply from a subset of fields, and then deletes or marks the proposal handled without the standard carry-out/source-reservation handoff. Running purchase-field validation and the requisition delete trigger does not first move the proposal's demand links to the new purchase line.
+
+Require both proposal-consumption intent and a visible supply conversion. Do not flag an isolated deletion of an unwanted suggestion, an ordinary purchase-order API, or the standard carry-out engine's own insert/delete sequence.
