DI Error: (-223) Deleting rows not supported for object Fiscal IDs for BP Master Data

First, I sent a BP with BPAddresses and BPFiscalTaxID/TaxId0 through the integraiton (B1iSN, DI API using the XML interface of B1), It is OK.

But B1iSN got this error when update the BP on an existing BP(Created before), In the XML file , I actually added an additional ship to address, Why it says "deleting rows error"
