Dear Experts,

I GR ref. PO when I fill Date of Manufacture and press enter system not calculate SLED/BBD (Material Master maintained Total shelf life), but system will be calculate SLED/BBD when I press the button "check".

In my exp, field SLED/BBD will be calculate when I enter Date of Manufacture.

So, I want to config field SLED/BBD calculate when I enter Date of Manufacture.

Note: I tried to config in OMJ5 but doesn't work.

Could you please guide me?

Thank you.
