Hi Experts,

SAP MDG Runtime Error is occuring when user selects link Create material Change request.

SAP MDG version: 7.1

The change request was working fine previously. Suddenly CR started giving dump.

Material number in staging area was not getting generated. We investigated the error and found that Number range of Object MDG_BS_MAT had reached the maximum limit i.e. 999. (We are not sure whether it gets stop here or we need to extend the limit in number range manually) any light on this topic is much appreciated.

Changing the number range and NR status has solved the issue. Please find the below changes.

Old Range: 0000000000000100 to 0000000000000999

The number range was increased from 999 to 9999

New Range: 0000000000000100 to 0000000000009999 NR Status: 1009

Post configuration change, Create material change request started working fine. This solution worked in our case.

@Experts- Please advise if the above solution is the correct approach to resolve the issue.
