MIGO running very slow (Schedule agreement)

Hi all,

I have problem with MIGO - more specifically is performance. First person created Schedule agreement and next person does to this schedule agreement ASN (inbound delivery in VL31n). Always is everything ok, but I have a few materials when I try confirm in migo I need wait a 30 min sometimes 1-2 hour. Does anyone knows why this is happening ?

Thanks in advance.
