GST- TDS Payments to Authority

hello

Our client is having Multiple Locations/INV ORG across different states and more than one Location in same state in a Operating Unit.

They have been maintaining AR and AP transactions in all the locations.They have been receiving payments from customers in all locations in assigned banks to Location.

But they do payment from one Location. e.g. Location Z which comes under same OU in question.

Transaction tax - First party registration is at Inventory Org level which includes location Z.

Withholding tax as required registered at  OU level.

Pl clarify:-

While making GST payment to authority they make single challan for a state and pay from Location Z . How this payment will get split into Locations accounting. They do not want any workaround of manual entry in locations.
