In OMS2, Checked the box(X) , External number assignment without check box.
Number range intervals maintained 00000000000000001 to Z9999999999999999,
Requirement is to go for external number ranges for materials,i was able to create alphanumeric partnumber ,
but when i am creating numeric partnumber (1234) it is throwing me an error.
With this material type, ext. material no. must not contain only numbers
