Entering configuration for contract item is not possible

Hi all,

When creating a contract using item category KMN, I should have the option of entering the configuration for the material X, maintained as follows:

Material X - (HALB)

Client Specific Configuration

VARIANT = 'X'

CROSS-PLANT CM = MATERIAL Y

CLASSIFICATION

CLASS TYPE 023 "maintained"

BATCH MANAGED = X

Material Y (HALB)

Client Specific Configuration

VARIANT = ' '

CROSS-PLANT CM = ' '

CLASSIFICATION

CLASS TYPE 023 "maintained"

CLASS TYPE 300 "maintained"

BATCH MANAGED = X

When I create a contract and enter this material (item category KMN) I don't get the CONFIGURATION popup and if I click on the configuration button It shows me all the right characteristics there, but not open for input and empty.

Any idea on what could be missing?

Thanks

Leonardo
