Middleware -BDoc is failling --Message "Other city only with PO Box "

Hi,

In SAP CRM 5.2 system , we have performed the data download of Customer data from SAP R/3 4.6c into CRMusing Middleware .We are facing certain validation errors in the BDocs.

The error message that we receive see in this BDoc is "Please specifyother city only with PO Box or company postal code". But when look at this data in the ERP System, none of these three fields (Other City (HOME_CITY), PO Box (PO_BOX), company postal code(POST_CODE3))have any

data in the ERP Customer record.

Can someone help me on this ...Points will be rewarded.

Regards,

Ritvij
