As per our requirements, we need to add couple of fields to ANSI X.12 834 4010. I did below steps
1) ANSI.X12 --> Editor --> Message Editor
2) Click on Copy control key.
3) Created Z control key and assigned 834 message type to the Z control key.
4) Maintained an entry in ANSI X.12 --> Control Key Scenario Association.
After the above steps are done, i try to edit the message.
1) ANSI.X12 --> Editor --> Message Editor
2) Drop down my custom control key.
3) Did the changes and save --> It is triggering a dump, when i'm trying to save.
Error is
java.lang.NullPointerException: while trying to invoke the method com.sap.customization.comp.wdp.IPublicCustomizationComp$IDropdown_subversionElement.getSubversion() of a null object returned from com.sap.customization.comp.wdp.IPublicCustomizationComp$IDropdown_subversionNode.currentDropdown_subversionElement()
Are we missing anything, I did not find any OSS notes for this error we are on SP2.
