• What is the cause and solution for SAP error message /SAPAPO/MAT453 - The Gross weight is smaller than the Net weight ?

  The SAP error message /SAPAPO/MAT453 indicates that there is a discrepancy between the gross weight and net weight of a material in the SAP Advanced Planning and Optimization (APO) module. Specifically, this error occurs when the gross weight (which includes the weight of the packaging) is smaller than the net weight (which is the weight of the product itself without packaging). This situation is logically incorrect, as the gross weight should always be equal to or greater than the net weight.
