question

1- This is how tax created:-

val taxRate = TaxRate()
taxRate.isDefault = false
taxRate.name = ml + "ml"
taxRate.rate = 0
taxRate.taxAmount = taxAmount

val isCreated = inventoryConnector().createTaxRate2(taxRate)
taxId = isCreated.id

2- This is how tax applying.

val listTaxRates = ArrayList<String>()
inventoryConnector().taxRates.forEach { i ->
    if (taxId == i.id) {
        listTaxRates.add(i.id)
        return@forEach
    }
}
inventoryConnector().assignTaxRatesToItem(
    itemId,
    listTaxRates
)

:- So I want to add tax to the specific inventory item, Suppose we have 5 inventory items so I want to add custom tax(What tax we want to add) to specific inventory item.

:-So at this time tax is created but not applied to the item.
