The SAP error message /PRA/VL_SD016 indicates that there is a mismatch between the volume type and class of the material in the Sales and Distribution (SD) module, specifically in relation to a VCR (Volume Control Record) formula. This error typically arises when the system is trying to process a sales order or delivery that involves a material with specific volume-related characteristics.
Cause: Mismatch in Volume Type/Class: The volume type and class defined for the material in the system do not match the expected values defined in the VCR formula. This can happen if the material master data is not correctly configured or if the VCR formula has been changed without updating the related material data. Incorrect Material Master Data: The material master may not have the correct volume type or class assigned, leading to this error when the system attempts to validate the data against the VCR formula.
