Answer Posted / nagaraju bhatraju
generate a sequance values through sequesnce generator and
connet it to the target get the max value of it every time
from unconnected lookup and set this value(maxvalue) to
mapping variable so that the last max value will be stored
in repository. Once the sequance generator is reached its
max value say 2billion , set the property reset to 1 so
that sequence generator will start again to produce
sequance numbers .
and in experession write the logic like
new_seq=max(mapping_variable+sequence_generator (value)
then it is like 2million+1...2......(seq_gen)
every time sequance generator will reset to 1 after
reaching its max value
