Summary :
SAP Note identifies a bug that allows manual setting or unsetting of the return indicator in purchase order items even after associated follow-on documents exist, potentially leading to data inconsistencies. Additionally, modifications to material or plant, or substitution of items via reference document updates (like contracts or requests for quotations) remains susceptible. The problem stems from a program error. A correction is available to restrict these changes once a delivery, goods receipt, or invoice receipt has updated the purchase order. Updated functions will be included in Support Packages SAPKH46B34 or SAPKH46C26, with manual installation guidance provided.
