Update PO Item Management Codes via API for purchase orders

Account name : ICC Sydney
Region : APAC
Client version (Enterprise) ;25.4
Description of the issue :
- What does the client want to do? Why do they want to do this?
  - Customer C# console application calls the PO Item API endpoint to update the PO Item Management Code to some other value
  - The PO item distribution has for ex: Liability hence references a Non-Asset/Expense GL account.
  - While updating the console App returns warning/error ''10041838 ***** -- Non Asset/Expense GL Accounts have been entered into the purchase order distribution. Do you wish to continue? .''
  - When tested through Main menu > API help, we were able to recreate the error. But customer want to know if there is any option to override the validation message in the PO Item Update API call.
  - They have noted that in Relationship API we came across a feature that allows validation errors to be bypassed using the Option.Subjects parameter(screenshot below). Advice if there is a way to bypass the PO Item validation error.
What you've already tried or suggested. Why does this not work?
- Tested on Sample environment and able to recreate the error for PO 10041581
Business impact if not resolved ; Normal : They need to know if this can be achieved?
