Running MDG 7. We have had a custom material master change request set-up for a while now and everything has worked as it should.
However this morning when we came to run a change request through we encountered a problem...
As soon as a Roundtrip event is triggered (e.g.from using a drop down) all of the fields in the Basic Data UIBB lose their values, but all the other UIBBs retain their values. Running the check entity method through debugging shows that it_data is not being populated by the input values.
We also have certain fields defaulting using the Rule Service BADI (MTART, MEINS etc.) and even though these are being defaulted, as seen in debugging, they are not shown on the screen. Some of these fields are used in different UIBBs, MEINS is in the dimensions UIBB and the default value is being shown.
This has led me to believe that there is something wrong with the Basic Data UIBB but all the settings look fine.
What could cause standard and previously working custom fields to no longer populate in the back-end tables? It's almost as if the UI input fields are not connected to anything. How could this be?
Thanks in advance for your help!
