Cost Change Amount inclusive of tax

Hi,

Can you help me in understaning whether the cost change created in RMS the cost change amount includes TAX or excludes it.

In our Current system Commercial users are creating the cost changes excluding the VAT/TAX amount, now we have received a request that users will upload the cost change amount inclusive VAT/TAX from vendors/supplier.

For this do we have to make any change (configuration/code) level so that the users can in cost change amout along with the tax.

Below are my current settings in system options.

system_options.VAT_IND='Y'

system_options.CLASS_LEVEL_VAT_IND='Y'
