The implementation of Swap Trigger PLUs occurs seamlessly at the POS.
Consider the screen shots below. The first shows the entry of the Classic Combo Deal with a protein choice of chicken and bread choice of wrap. This combination does not trigger a swap and the production ingredient reported at the KMS is the (3) chicken tenders associated with the Wrap PLU.
However, in this example the Classic Combo Deal is entered with a protein choice of vegan ‘chicken’ and the same wrap bread choice. The inclusion of the vegan ‘chicken’ has triggered the swap from wrap to wrap. and the production ingredient reported at the KMS is the PB chicken pattie associated with the Wrap. PLU.
Note: While in the QSO build list the PLU displayed is wrap (the original PLU). Once saved the swap trigger PLU (vegan ‘chicken’) causes the lookup of the swap items list, the exchange is made and wrap. is displayed in the POS and KMS order windows.
