hello...i have an external source system which is a SAP client, I have a table with the fields i wanted, when the field of the table change to "ctmd end", the abap program in this source client will trigger the process chain in SAP BW and the selection of the infopackage which is a business date will be triggered as well to load the data based on the business key date in the source systems. I am new in abap program and wanna know can this be done so? If can, how can this be done? Thanks!
