Scenario
Sometimes it is required to feed data from source fields which are of length > 60 into BW. In such cases while populating target fields into BW we get blank spaces.
Ex:
We have 3 source fields of length 100 and we want to populate fields in BW target. We have entered 50 characters each in 3 fields of source system (total characters 150). Now we want 1st field in BW to have 60 characters and 2nd field to have 60 characters and 3rd field to have rest 30 characters.
Code needs to be written in two pieces, one in Start routine and other in end routine.
Source fields METRIC_HELP1, METRIC_HELP2 and METRIC_HELP3
Target fields /bic/zdbcmnt1, /bic/zdbcmnt2 and /bic/zdbcmnt3
