Hi Dirk,
Thanks for the link to the SAP note and RDM document.
However I dont see the relation to my question.
In the ETL process during T I have to retrieve a value from a customizing table that I require for migration file. In other words: an enrichment of the migration files is required.
It could be done in a QUERY I think and with a LookUp function, however the conversion table the lookUp function has to retrieve the value from is no a DB table: it is a table in SAP ERp, that might change frequently. So the select single has to happen during Transform.
Please describe
