Special Features for Materials
Processing of a material in Engineering Change Management depends on which function you used to create the material.
Creating a Material
You can create a material with reference to a change number using two functions.
You can change the material immediately with reference to a change number whose valid-from date is not in the future. The changes you make are then valid with immediate effect (as of today’s date) or as of the date in the past.
There are revision levels for these materials.
The system does not create the material master record until the scheduled material is activated on the valid-from date of the change master record. The current date is set as the create date. You can then process this "real" material master record either with or without a change number.
If you schedule to create a material with reference to several change numbers, the system overwrites the existing organizational areas when it is activated.
As an example, you schedule a material with reference to the change number N1 and maintain data for engineering design and materials planning.
You then schedule the same material with reference to the change number N2 and maintain data for engineering design and storage.
You activate the material for the valid-from date of change number N1. If you activate the material for the valid-from date of change number N2, the engineering design data is overwritten. Only the state with reference to change number N2 is saved.
There are no revision levels for scheduled materials.
Change material
There are two functions that you can use to change a material with reference to a change number.
You should then activate the scheduled change for the valid-from date of the change master record.
