What happens to the costs reflected in purchasing documents when prices are updated in material master data?

The correct answer indicates that when prices are updated in material master data, they do not impact the costs in previously-prepared purchasing documents. This is because purchasing documents represent historical transactions that have already been committed and need to maintain their original values for accountability and auditing purposes.

Updating prices in the material master data only affects future transactions or documents generated after the price update. Thus, any existing documents stand as records of the agreements made at the time of creation. This ensures that all stakeholders have a clear understanding of the costs associated with past transactions, avoiding potential confusion or discrepancies in financial records.
