Order planning fails in sub domain but plans via master domain

Hi All,

In our implementation, we are interfacing orders to various sub domains under a master domain and planning them instantly after order creation. This requirement is to isolate different types of order releases. There are one particular sub domain where when the order is interfaced, the order is created but fails to plan instantly. When we login to master domain or the sub-domain, we are able to plan the order manually. Is there something we can check to begin with as to where is the root of the problem.
