Trying to add ProductRatePlans through code; found not so efficient method, is there a better way?

[vinar]

I am trying to add specific ProductRatePlans on an existing Quote through the code and found this useful article. The article has an example at the end of the page which talks about how to "Add a Product to a quote with a specific rate plan". For some reason this idea is not scalable when you are adding ProductRatePlans from multiple Products and requires a lot of looping. Is there a better way to add specific ProductRatePlans?

Hi @vinar, 

I do have a ticket from you for the same issue and I will update this thread after my investigation towards it.

Thanks, @Hina, and @doyeli for helping me with this. I was able to add Product Rate Plans using the below code snippet.

Id quoteId = 'xxxxxxxxxxxxxxxx';
List<Id> prpIds = new List<Id>();
prpIds.add(productRatePlanId);
prpIds.add(productRatePlanId);
// Get charge groups ready to be added
List<zqu.ZChargeGroup> chargeGroups = zqu.ZQuoteUtil.getChargeGroups(quoteId, prpIds);
for (zqu.zChargeGroup chargeGroup : chargeGroups) {
    // Update chargeGroup with new quantity and discount
    List<zqu.zCharge> charges  = chargeGroup.zCharges;
    zqu.zCharge charge = charges[0];
    if (charge.IsQuantityEditable) {
        charge.quantity = '123';
        zqu.zQuoteUtil.calculateChargesOnQuantityChange(chargeGroup.zCharges);
        charge.discount = '36';
        zqu.zQuoteUtil.calculateChargesOnDiscountChange(chargeGroup.zCharges);
    }
}
zqu.ZQuoteUtil.addChargeGroups(chargeGroups);

Thank you so much @vinar

Just to enhance on what @vinar has documented earlier, here is an example code to set/populate  a custom field value as part of adding charges programatically

zqu.GlobalCustomFieldDefinition.CHARGE_FIELDS = new Set<String>{'test_data__c'};
List<Id> prpIds = new List<Id>(); 
prpIds.add('a0Rf4000001NnOS'); 
//prpIds.add('a0j1D00000080qsQAA'); 
// Get charge groups ready to be added 
List<zqu.ZChargeGroup> chargeGroups = zqu.ZQuoteUtil.getChargeGroups('a0if400000BqP3UAAV', prpIds); 
for (zqu.zChargeGroup chargeGroup : chargeGroups) { 
// Update chargeGroup with new quantity and discount 
List<zqu.zCharge> charges = chargeGroup.zCharges; 
zqu.zCharge charge = charges[0]; 
if (charge.IsQuantityEditable) { 
charge.quantity = '123'; 
zqu.zQuoteUtil.calculateChargesOnQuantityChange(chargeGroup.zCharges); 

} 
  // Read a custom field on zCharge
  charge.chargeObject.get('test_data__c');
  // Update a custom field on zCharg
  charge.chargeObject.put('test_data__c', 'test1');  
} 
zqu.ZQuoteUtil.addChargeGroups(chargeGroups);

this is a great example, thanks @doyeli
