Mark, The problem with moving closed positions to an archive portfolio or sub-portfolio is remembering which investment belongs to which subportfolio where two or more subportfolios held and sold the same security. This is a problem since FM does not maintain a db for each security in the master portfolio but rather repeats the same investment in each subportfolio, eg cgmrx.dat, cgmrx1.dat ..........cmgrxn.dat. I have talked with you about this before. CGMRX is CGMRX. Its price and distribution activity are what they are without regard to which or how many subportfolios may hold it.
Unless separate archives are set up for each sub you have a problem is there is a need to open a previously closed investment. Using Advisor I have numerous subportfolios many hold the same security. I really know of now way to do this. Overtime, the db grows and grows.
