SO/PO entry can skip the non-working day

Hi Experts,

Anyone can provide the workaround how the SO/PO entry (P4210/P4310) can skip the non-working day which setups on P00071 (Shop Floor Calendar) ? The WO entry (P48013) will provide the warning code 1921 if non-working day assigned to, however no any information provided but just accept the non-working date via P4210/P4310. Thanks in advance for any your comments !

One quick option which comes to my mind is to change the warning to error. This is crude way of getting it done but you will have to find the impact of changing the warning into error if its ever used by other programs.
