Generally during documents/journals creation users will attach the dimensions depened upon the transaction type.
But in Axapta we have Inventory management > Setup > Posting > Dimension link. .
I could not understand why we need to assign the Financial dimensions to Sites . ? because even we purchase the material for the same site , but dimension codes and values will change transaction to transaction. Then what is the advantage to have this functionality and how can we implement in a practical business.
Many businesses will dimension control teh sites as they are physcial and financial cost centres. By linking them if the user changes the site on the transaction document (sales order for example) the financial dimension is automatically altered.
