#337

Short Description and Why It's Useful

• Updated the code for the Missing SKU modal, which was previously not displaying the missing SKUs of products in the list.
• After debugging, I found that the fetchOrderDetails action written for Purchase Orders had issues, causing conflicts in the list of missing items. Rewrote the logic of the action and made corresponding changes in the modal component as well.
• The fetchProducts function was also not working as expected, so I corrected it by adding pagination using a do-while loop.
• Replaced the shopifyProductSKU field with identification, which was conflicting with the regular purchase order flow.
