A company uses Dynamics 365 Business Central.

Comprehensive Detailed Explanation

Exact Cost Reversing Mandatory When enabled, this ensures that when a return or credit memo is posted, the cost reversed exactly matches the original outbound transaction cost. This guarantees proper cost application and avoids average or incorrect costing.

Select Return Receipt on Credit Memo This option ensures that when a sales credit memo is posted, the return receipt is automatically processed at the same time. It ties together the financial and physical return in a single step.

Yes for Default Item Quantity Setting this parameter ensures that sales documents (including credit memos) default the quantity to 1 when a new line is created, which reduces manual input errors and supports the requirement to always show a default quantity of one.

Why not the others:

Choose No/Blank for Default Item Quantity would leave the field empty or require manual entry.

Add a Sales Credit Memo Account in Posting Setup only defines posting accounts, not cost matching.

Archive Return Orders is about document retention, not transaction automation.
