ALE : conversion rule for field value to become null
I need to pass a material from one system to another with ALE. The problem is that the field marc-prctr (profit center) of this material is populated in the first system, but it does not exist in the second, so I assume transaction bd79 should be used to convert somehow the value of prctr to initial.
How can I do that??? I have already tried defining a conversion rule and assigning it to message type MATMAS, segment E1MARCM, but it did not work.
