Conv Routin in DataSource
This is the generic DataSource created in R/3, and replicated into BW. In RSA1, I double-click on the DataSource. In the Field tab, I can see the list of fields used by this DataSource. However, I noticed that the Conversion Routine exist for the field PROID in this DataSource, under Column SS Conv. Rout. In the F1, it says:
Conversion Routine in Source System (Outside of BW)
Why the conversion routing is assigned to this field? What does this mean? How can I remove this?
