While assigning infosource to datasource, we are getting an error saying "Field length in the structure is greater than 16 (Message type E)".
After debugging we found that in the table RSADMIN there should be an entry with
object = RSAR_LONG_FIELDNAME and
Value = Comm.structure name.
We were not able to find the maintanance view or transaction to maintain this entry.
Any idea from where can we maintain this value would be very much helpful.
