COPA DATASOURCE

Dear EXperts,

i am having the COPA datasource 1_CO_PA333ZPAC4 and the user requested three new fields.

The required three fields are already available in the datasource when i checked the same through KEB0,but they have not taken till now.In KEB0 i am not able to change the datasource.

i think in this case there is no need to re-create the datasource again right.

please correct me regarding the same and let me know in which transaction i can change the datasource for selecting the required fields.

Regards,

Sunil Kumar.B
