Why we do recording in Call Transaction in BDC?
when we want do the call transaction we want know what is technical information of each field .
so we go for recording. tcode is ‘SHDB’.
it will store the progarm name, screen no, field name, field value for each field on the
screen.
Transaction is set of screens in a predefined sequences, its record the particular transaction and that can convert the record into program. In order to know the screens and there values., here doing recording.
eg. if we transfer data manually it takes record one by one . if we do recording then it takes large amount of record automatically when recording runs.
in future we have transfer data of same fields then we will run recording & it will transfer the data
why we are using continue after commit check box??
