I am new to sap bi. What is meta chain
Hi Nikhil ,
A Meta chain is a chain containing other chains as its processes. In simple terms its a parent chain having other local (Sub) chains which it triggers.A meta chain is basically used to combine runs of various chains like in my system we have transaction data chain and master data chain .Now transaction data runs only after master data completes.So we have a meta chain which after the start variant has master data chain as first step and transaction data chain as second step.
Hope it helps.
