How to or which table i can find Sales Tax Code in CRM

Hi,

I need to get Sales Tax Code(mwsk1) in BADI 'CRM_COND_COM_BADI'. if i use CRM_ORDER_READ( ET_PRIDOC) or CRM_PRIDOC_READ_OW it is going into endless loop. So i can't use these Function modules in CRM_COND_COM_BADI.

Can you help me table or any other way to get sales tax code of Pricing conditions that appear on the sales order in CRM.

Thanks,

Praveen
