How to default charge account from costing of the departments

Summary:

Hi All,

While creating requisitions charge account is defaulting from the default expense account added at employee level.

Our client is having the requirement to default charge account based on costing of the departments, so we need to default Reporting unit, Responsibility center, sub segment from costing of department and the third segment (Natural Account) needs to be defaulted from the mapping set if an item is linked to the account.

Basically, if a requester belongs to some A department, then 1, 2 and 4 segments in the charge account must be defaulted from costing of the department of A and the 3rd segment must come from the mapping set.
