What is the better option to programming in network data sharing:

1) Using the scatter and gatter command, and manually locking, using the rlock() , flock() and isrlocked(), set reprocess, ......

2) Using the buffermode property, and this way use the tableupdate() , tablerevert() , begin transaction,.....

I´m using the dataenvironment, datasession property type 1, buffermodeoverride property type 3.

Thanks
