ALE configuration - change pointers

Hello,

Iam trying to create idocs whenever there is a change in the customer master i need to trigger an idoc.Iam trying to use change pointer for that.

I checked in bd61,bd52,bd50 all the settings are ok.

but still idocs are not created when i change the customer master...

Do i need to run BD12(RBDMIDOC)...?or am i misssing any other settings...(When i tried to use bd12 to send customers iam able to generate idocs so my model is working...).

Second question I need to send DUNS number in the idoc which Iam not able to find in DEBMAS/DEBMAS04 how can i send that...?Even if i extend how can i populate it ...I dont find any user exits for MASTERIDOC_CREATE_SMD_DEBMAS which holds the control record....?

can anyone help....

Thanks

Larry
