Why does AR Invoices and Memos display positive amounts for Credit Memos, while Landed Cost allows negative amounts?

Question

Hi Everyone,

I noticed a difference in how document amounts are displayed across different screens in Acumatica:

On the Invoices and Memos AR3010PL, both Invoices and Credit Memos display the Amount as a positive number, where the document type determines whether it increases or decreases the balance.
However, on the Landed Cost PO3030PL screen, negative values are displayed directly for cost reductions or adjustments.

Could someone help clarify why Acumatica designed this differently? Is AR3010PL relying on the DocType to determine the balance impact, while Landed Cost needs negative/signed values to run its allocation logic?

Thanks in advance for your insights!

Hi ​@nomii,You actually nailed it! The difference comes down to Document Type logic vs. Line-Level Allocations:AR Invoices & Memos (AR3010PL): AR relies heavily on the DocType (Invoice, Credit Memo, etc.) to drive the accounting. Everything stays positive on the screen and on the lines because the document type itself tells the system whether it’s a debit or credit when posting to the GL.Landed Cost (PO3030PL): Landed Cost is a line-based engine rather than a traditional billing document. Since you can have both cost additionsand reductions inside the same document to adjust item costs, the lines need explicit positive/negative values. It sums those signed lines up for the total, so it doesn't need separate "credit" or "debit" document types.Hope that helps clear up why they built them differently!
