System Response
Table T440A contains a list of fields for each object which cause anentry in the MRP File if they are changed.
Via these entries, on the one hand the data definitions are defined foreach object and on the other hand, the compare instructions are defined
for each object.

Procedure
You can create or delete new fields for existing objects and tableswhich, if are changed, should cause an entry in the MRP File.
If you want to create new fields, do this by creating the desiredfields for the object in question and press F11. Enter the object inthe window which appears. By pressing F11 again, the data definitionsand the compare instructions are created.
The data definitions and the compare instructions are saved in thevarious application programs and are also amended there. If a newobject or a new Table is created, then the necessary instructions willbe missing from the application programs. This means that no entry canbe made in the planning file for the new object.
If, however, you want to make an entry for the new object, then youmust amend the coding in the appropriate program.
