TI-API: Unable to input quotation# and change the CRD date

Part Number: TI-API

Tool/software:

Hi team,

We have tried to input quotation# and change CRD date, however it keeps on returning error.

Sample Change Order Request I submit to update quoteNumber/ change CRD:
{
  "order": {
    "orderNumber": "XXXXX",
    "checkoutProfileId": "XXXX",
    "lineItems": [
      {
        "customerLineItemNumber": "1",
        "lineItemChangeIndicator": "U",
        "tiPartNumber": "XXXXXX",
        "customerAnticipatedUnitPrice": 0.33,
        "quoteNumber": "XXXXXX",
        "customerCurrencyCode": "USD",
        "schedules": [
          {
            "requestedQuantity": 14000,
            "requestedDeliveryDate": "2025-02-24"
          }
        ]
      }
    ]
  }
}
However, it still returns this error: 
"messages": [
            {
              "code": "TI-TXT-062",
              "type": "ERROR",
              "reason": "customerLineItemNumber 1 cannot be changed",
              "message": "customerLineItemNumber 1 is in process by TI and cannot be changed. If you are still having issues, contact TI customer support https://support.ti.com/csm"
            }
          ]
Please kindly advise on what we could do to solve this issue. We have tried looking for CSC, but we do not have any proper answers.
Best Regards,
Ernest
