Automatic Freight settlement for STOs

Hi,

Can we have Automatic freight stettlement for STOs just like we do MRRL in normal standard POs?

What are its IMG configuration and any other configuration if required?

Also there is option to settle planned delivery cost in MRRL, then why it is not picking the STOs for freight settlement?

Following Settings already Done
1.) ERS checked in Vendor Master
2.) IMG MM--->LIV--->ERS--->Specify Automatic Stettlement of Planned delivery.

3.) Since we dont have Invoice Tab in STOs hence there is no option to tick ERS in STOs. If it is possible to bring ERS checkbox in STOs kindly suggest the configuration needed.

Regards,

Ashish.
