Hi Experts,

I have an issue related to purchasing view of material master with field "Post to inspection stock".

Field is hide for one plant A and and enable for other plant B. Due to this, all materials of plant A is not posted to inspection stock during creation of PO and everytime user changes manually.

Material type is same and no specific sreenselection for both plants.

Could anyone help me out how to resolve the issue. please let me know if there is any plant specifc field selection in material master customization.

Thanks in advance for your help.
