dump due to "material deviation"

[former_member190992]

hello colleagues,

I am facing a strange problem with MMCL Tcode.

when I try to display the batch stock through MMCL, a dump is generated.

after debugging, I found that the root cause is due to the material deviation in the batch master data.

with many test I found that each time I fill it beginning with 90X 60xxxxx (see attachments), the dump appears.

could you advice?
