Configuring the transaction MB21
When using transaction code MB21 you are a.o prompted to insert the movement type - ie. 201 for goods issue for cost center.
You may also use the menu bar, where you select Movement Type => ie. Consumption => Cost center. This results in the insertion of same movement type as described above.
If you have configured your own movement types you may like to configure the menu bar so it is selecting these own configured movement types instead of the standard movement types provided in the standard SAP system.
If anyone has a clue on how to make this configuration, please do not hesitate to respond.
