I'm working in Informatica support project:
In generally we say any new req. "ticket" Ex: INIT1113371
using this ticket no. we can able get the document through
remedy tool
and just go through the document and understand the
requirement. adding new column or remove column like that.
If we are removing any column means, first check it out
this column refered any table or not
after that only. we can remove the particular column.
adding new column is very easy. 1-1 mapping.
after finishing we prepare migration document. we will send
to customer for cutomer requirement.
