Reason For Rejection for ATP with product substitution line in sales ord
Hi we are using Rule Based ATP with product substitution. SO we have a TAPA and a TAN line for a material for which the system does product substitution. If a material is fully delivered standard SAP does not allow you to reject that line item. However in case of product substitution we have 2 line items one with item category TAPA which is the main item and a sub item with item category TAN. In case if the material is fully delivered system still allows me to reject the TAPA line item. I think this is incorrect.
According to my previous testing I was not able to see reason for rejection field open in sales order for fully delivered line item.
But from today I am seeing that reason for rejection field for higher line item is not grayed out in case fully delivered line.
Is there any config for this? In item category or in order type or from ATP side? Anything helpful will be greatly appreciated.
