Hi Team,

Business case here is as below. 

We have given option to user to add/remove multiple records to ADP records. 

So now Payload count is not freeze it depends on the records available in ADP. 

For Single Payload Processing we were good, since we can apply for loop and get records send for REST api as single payload. 

But here we need to write payload in to for loop first , then created payload we need to submit for one REST API. 

Is it feasible ? If yes any suggestion are welcome. 

We have one rest API in Inventory for inventory Staged Transaction as below for batch processing.
