New Primary Location Change on Sales Order

Hi,

we have closed a w/h & transferred all the Sales orders to the New w/h.

Also we moved the existing stock through IT.

Now the closed w/h was having only blank primary location.

User created new primary location in New w/h.

We need to update this new primary location on the existing sales orders which are transferred to new w/h.

Kindly suggest the method to do so.

Regards,

Shakil Mulani
