Why we Maintain the data in Trxn # CL20N / CL24N for Release Strategy ?

Question

Dear All Gurus,
Please resolve my Query , that during maintaining the Release strategy for a P.O , i used to create characteristics for defined values such as plant , currency , doc. type etc, then creating class and assigning these characterstics with this class created.
Now after this i had create Release Group , Release Code and Release Strategy and assigned the Rel. Code with the Rel . Str and in Classification tab i had manually mentioned all those created Characterstics in CT04 and finally saved this Process.
Till now i had not at all made any entry in Trxn # cl20n.
But when i had create a P.O with all  the values as same as defined in characteristsc , the Rel Str got triggered succesfully.
My Question is that , what is the use of mainiating data in Trxn # CL20N & CL24N ?
Please clarify my doubt.
Many Thanx in advance.

Answer 1

it is just another way to maintain the same thing in the same tables. Classification notspecific to release strategies, materials and batches, vendors and customers can be classified too.
You can do this from withion those objects, or from the central classification menu using the classification transactions.
People here recommending this for production system after you have transported the strategy from developement to production. Becaues classification is master data and cannot be transported the usual way. And many here do not know how this can be done with ALE
