This field is enabled if one of the two conditions apply:
The Allow GL Account override when posting costs box is checked in JC Company Parameters (GL Cost tab)
The Allow GL Account override when posting costs box is unchecked, but the GL account defaults as null (blank).
The transaction GL account defaults as follows:
If an override account is defined for the phase in JC Departments (Phase Overrides tab), defaults the override account.
If no override account is defined for the phase, defaults the GL account defined for the specified cost type in JC Departments (Cost Types tab).
If no GL account specified at either the phase or cost type level (in JC Departments), defaults as null.
If no default account was specified, or if allowing overrides and you are overriding the default, enter the GL account to charge for this material cost. Must be a valid GL account set up (in GL Chart of Accounts) with a ‘Job’ or ‘null’ sub ledger code.
