Hi,

I am installing one solution in LN but its showing PS001001001 solution as dependancy. I search this solution in support.baan site but didn't get it from there. Can anybody tell me from where I will get this solution?

It is part of the Tools Service Pack/Feature Pack-1 upgrade (you can order those CDs from the Support site).

It seems that you manually changed the Base VRC of the Update VRC to B61_a1 (or 7.6_a1_tt in case of tools). After initial installation it was B61_a and 7.6_a_tt. You were allowed only to install solutions for these Base VRCs. By installing new Service Pack 1, PMC will automatically change the Base VRC to B61_a1 and 7.6_a1_tt. After that you will be allowed to install solutions only for the Base VRCs B61_a1 and 7.6_a1_tt. This is the mechanism PMC uses to prevent that you install the wrong solutions for the active Service Pack.
