Availability Check in Replenishment Delivery against STO

Hi All,

While creating sales order system check  available stock then it will allow to save order. If the stock is not available or reserved against other sales order/ STO/ Replenishment delivery , it doesn't allow to save the sales order

But if the STO is created , we can do the PGI even for the stock assigned against the Sales order.

How can we restrict PGI in case the stock is reserved against the sales order.

This functionality is working fine for Sales order but not for STO replenishment deliveries.

We have maintained all the details like checking rule, availabilty check, etc.

Kindly provide your valuable comments.

Thanks
