Checking Status Entries 
When you carry out a transaction in the SAP System in a particular object, the system first checks whether:
There is a status entry for the object
The business transaction is permitted for the object (combination of funds center/commitment item/fund).)
If there is no status entry for this object, the system uses the closest fitting entry for checking purposes.

You want to enter funds reservations for the combination <Funds center 1/commitment item 2/fund 3>. There is no status entry for this particular combination. This being the case, the system searches for other suitable combinations, for which there are status entries.
It finds entries for the following combinations:
<Funds center */commitment item */fund *>
<Funds center */commitment item 2 /fund *>
<Funds center 1 /commitment item 2 /fund *>
In this case, the system uses the third status entry for the check.

The system automatically generates the combination <Funds center */commitment item */fund *> when you maintain any status.
Among the business transactions covered by the check are:
G/L account posting
Manual funds reservation
Payment transfers
Material procurement
