Dear community,

I am trying to create a data source based on SDA (HANA Source system) referring to an Oracle view in order to build a further data flow in BW.

After trying to activate I am notice an error message in HANA Studio which says: "Type mapping not supported: NCHAR -> CHAR". The entries in the respective tabel are only Text entries e.g. KG, L, M3 etc., so I do not see why the Type mapping in this case should not working.

Each effort to choose another Data type does not provide success. How can I define the correct data type or how do I have to receive the respective entries?

We are running on BW 7.5 on HANA SP5. Any idea would be great. Thank you in advance. Best regards, Stefanos from Munich/Germany
