Configure a CPQ Product to be priced in real time

A Quote Calculator Plugin (QCP) is needed in order to accomplish this use case. Using JSForce, a query can pull the correct pricing data when called.

A basic example of how to set up the pricing can be found below, where QCP_Lookup_Table__c is the Object from which the pricing is queried, and fields Partner_Discount__c (Percent) and ProductId__c (text) are on the QCP Lookup Table object. The Custom Script record's Code field contains the following text and sets the Quote Line's Partner Discount field based on Quote Line matching the Product Id field on the Lookup Table.
 

export function onBeforeCalculate(quote, lines, conn){
  if(lines.length > 0){
    var productIds = [];
    lines.forEach(function(line) {
      if(line.record['SBQQ__Product__c']){
        productIds.push(line.record['SBQQ__Product__c']);
      }
    });
    if (productIds.length){
      var productIdList = "('" + productIds.join("', '") + "')";
      var queryString = 'SELECT Id, Partner_Discount__c, ProductId__c FROM QCP_Lookup_Table__c WHERE ProductId__c IN ';
      queryString += productIdList;
      return conn.query(queryString)
      .then(function(results){
        if (results.totalSize){
          var discByProduct = {};
          results.records.forEach(function(record){
            discByProduct[record.ProductId__c] = record.Partner_Discount__c;
            
          });
          lines.forEach(function(line){
            if(line.record['SBQQ__Product__c']){
              line.record['SBQQ__PartnerDiscount__c'] = discByProduct[line.record['SBQQ__Product__c']] || '';    
            }
          });
        }
        });  
    }
  }
return Promise.resolve();
