In version 4.0 of data services we had an nvl mapping on a target field with a double datatype as follows that worked without issue:
nvl(QRY_FVA_SALES_TXT.Opportunity_Value,'')
We are upgrading to version 4.2 and now this statement fails with "Cannot insert the value NULL into column...."
It works if we replace the '' with 0. This change seems logical but I can't find any documentation on it. Any suggestions on how I can confirm that this was a designed change by SAP?
