PR material description not change with change in materil master

Hi,

When i am changing the description of material in material master, it is getting reflected when we see that component in CJ20N, but when we see the PR, the descreption is not getting changed in MR(ME53n), what should i do so that when i change description in material master, it gets changed in PR also as it is already changing in CJ20n.

Regards,
