If I have multiple PVOs available for a table column, which one should I select?
Summary: While mapping table columns to PVOs, I found in most cases we have multiple PVOs present. What should I consider while choosing a PVO?
Content (required): Attached is a screenshot from 23C mapping sheet. For column CUSTOMER_TRX_ID of table RA_CUSTOMER_TRX_ALL, we have multiple PVOs present. What should I consider while choosing a PVO for this column?
Till now I was randomly selecting any PVO, but for one of the SRs raised by me, it was recommended to use extract PVOs since the other PVOs are meant for internal use and are not ideal for extraction. But since in the past I have already used non-extract PVOs for extraction, I would like to know its impact. Is it necessary to use extract PVOs wherever its possible? What if an extract doesn't exist for a certain table column? Also, what if I chose a non-extract PVO even if there was an extract PVO available for it?
