Use/Self Assessment tax process

Hi Gurus,

What is the procedure of handling use tax/self assessment tax in case, where we purchase goods from one province and use it in another province?

At what time accounting entries will be posted related to use tax? When we purchase goods, there will be no tax but self assessment tax will be applicable when we use that material in another provice and tax rate will be applicable on the basis of province in which we used?

Please let me know what are the steps involved in this, how can we handle this requirement in SAP? What is complete process for this?

Thank You

Regards,
