Supply Chain Planning data POST failures using API

I am using following API to get the planning data and trying to update the planning data using POST operation.

/fscmRestApi/resources/11.13.18.05/supplyChainPlans/300000038721808/child/PlanningTables/300345947794325/child/Data

The API response is success but however planning data is not updated.

What could be the reason and steps to debug the issue?

Input Payload:
{
"TableHierarchies": "XXXXX",
"TableDataHeader": "XXXXX",
"TableData": "XXXXXX"
}

Response:

{
"TableId": 300345947794325,
"TableHierarchies": "XXXXX",
"TableDataHeader": "XXXXX",
"TableData": "XXXXX",
"Message": "The service was completed. Refer to message details for diagnostic information.
