Tax details missing in BP and Product master data

Hi experts,

I'm facing a problem in CRM 7.0. My BPs  (sold to party) into BP transaction don't contain the Tax Information after download from ECC.

I have the same issue Into the product tax details

I have reviewed all configuration about Taxes:

1. Tax Types and Tax Groups
2. Assign Tax Groups to SAP ECC Tax Classifications (Product)
3. Assign Tax Groups to SAP ECC Tax Classifications (Business Partner)
4. And I perform the Report: CRM_TAXCUST_VALIDATE to ensure my customizing.

But I don't have the TAX data into the customers and product after initla load.

Anybody have and idea what is the problem?

Thanks for your help.

Maria.
