Batch determination in PI Sheet

Hi Gurus'

I am working in PPPI environment. I am having requirement to do batch determination from PI sheet.

I have done all config and condition records maintained in COB1

but when I enter * in batch field and pressing enter system says enter allowed values.

and when I enter * and do F4 normal popup comes.

Please guide me in this case.

I am unable to see context menu in PI sheet, if any one knows how to enable context menu in PI sheet please guide me.

Thanks & Regards,
