EFFECT OF TAX PROCEDURE

HI

First we configured CIN settings (TAXINN procedure) in our 650 client (DEV clinet) later we changed to TAXINJ in DEV itself and again we changed to TAXINN only. Now the tax codes are not working while doing the MM transaction is coming stating that Tax code is not assigned to TAXINN procedure. Now i want to know is there any effect by chaning the tax procedure like this manner will effect the tax codes or not? Please help me in solving this issue.
