Discount Function - FIRST Application Strategy Issue

Functions
1

I have created Discount A (10%) targetting all products. I have 2 products in cart, so I should be getting 10% discount for both the products. But I am only getting the discount applied on the first product. See the function log :

{
  "operations": [
    {
      "productDiscountsAdd": {
        "candidates": [
          {
            "message": "Prod F 10%",
            "targets": [
              {
                "cartLine": {
                  "id": "gid:\/\/shopify\/CartLine\/0"
                }
              }
            ],
            "value": {
              "percentage": {
                "value": 10
              }
            }
          },
          {
            "message": "Prod F 10%",
            "targets": [
              {
                "cartLine": {
                  "id": "gid:\/\/shopify\/CartLine\/1"
                }
              }
            ],
            "value": {
              "percentage": {
                "value": 10
              }
            }
          }
        ],
        "selectionStrategy": "FIRST"
      }
    }
  ]
}

You might suggest me to add both the cartlines to the first candidate. It will work but consider the following case :

Discount A (10%) is there targetting Product X and Discount B (15%) targets Product Y both with FIRST strategy. So according to Shopify, it should apply the First Eligible discount to each cart line. So X should get 10% and Y should get 15% respectively.
But now , only the first discount is (Prof F 10%) getting applied and only to the first candidate(cartline 0 ).

{
  "operations": [
    {
      "productDiscountsAdd": {
        "candidates": [
          {
            "message": "Prod F 10%",
            "targets": [
              {
                "cartLine": {
                  "id": "gid:\/\/shopify\/CartLine\/0"
                }
              }
            ],
            "value": {
              "percentage": {
                "value": 10
              }
            }
          },
          {
            "message": "Prod F 15%",
            "targets": [
              {
                "cartLine": {
                  "id": "gid:\/\/shopify\/CartLine\/1"
                }
              }
            ],
            "value": {
              "percentage": {
                "value": 15
              }
            }
          }
        ],
        "selectionStrategy": "FIRST"
      }
    }
  ]
}

What should I do ?

Hi @mridul_final ,

See the application strategy docs.

__________________________________
All: Apply all the discount candidates to eligible cart lines. This doesn’t override discount combination or stacking rules.

First: Apply the first discount candidate to cart lines that satisfies conditions.

Maximum: Apply the discount to the cart line that offers the maximum reduction.
__________________________________

I think in your case, you want the all selectionStrategy.

Let us know how you make out!

Not really, According to doc, FIRST should apply the first discount candidate to cart lines that SATISFIES CONDITIONS. For all the cart lines that satisfies the condition, it should apply the FIRST discount right ?

Also let me improve the earlier scenerio :
Discount A (10%) is there targetting Product X and Discount B (15%) targets Product Y both with FIRST strategy. Discount C (5%) is there targetting Product X with ALL strategy. Then how will the operations be ?

Your help is much appreciated
