axapta - How to add an extra row to a custom lookup query? -


i created custom lookup on prodbom table , displays bom items given production order user can select items listed on bom. want them able select produced bom item (prodtable.itemid) in list (1 item). how this?

here current lookup:

static void lookupitemidbomsubset(formstringcontrol   _ctrl,                                   prodid              _prodid) {     systablelookup          systablelookup  = systablelookup::newparameters(tablenum(prodbom), _ctrl);     query                   query           = new query();     querybuilddatasource    qbds            = query.adddatasource(tablenum(prodbom));     ;      qbds.addrange(fieldnum(prodbom, prodid)).value(queryvalue(_prodid));     qbds.addsortfield(fieldnum(prodbom, linenum), sortorder::ascending);      systablelookup.parmquery(query);      systablelookup.addlookupfield(fieldnum(prodbom, linenum));     systablelookup.addlookupfield(fieldnum(prodbom, bomid));     systablelookup.addlookupfield(fieldnum(prodbom, itemid), true);     systablelookup.addlookupmethod(tablemethodstr(prodbom, itemname));     systablelookup.addlookupfield(fieldnum(prodbom, prodlinetype));     systablelookup.addlookupfield(fieldnum(prodbom, inventtransid));      systablelookup.performformlookup(); }

you try using temp version of prodbom, populate necessary information , use buffer perform lookup:

prodbom         tmpprodbom,                 prodbom; prodtable       prodtable; ;  //set table temp buffer tmpprodbom.settmp();  //first record, insert temp buffer select prodtable prodtable.prodid = _prodid;  tmpprodbom.linenum = 0; tmpprodbom.bomid   = ""; tmpprodbom.itemid  = prodtable.itemid; //...etc each field have/want available tmpprodbom.insert();  //insert rest of records while select prodbom prodbom.prodid = _prodid {     tmpprodbom.linenum = prodbom.linenum;     tmpprodbom.bomid   = prodbom.bomid;     //...etc each field want available     tmpprodbom.insert(); }  systablelookup.parmtmpbuffer(tmpprodbom);  systablelookup.addlookupfield(fieldnum(prodbom, linenum)); //etc  systablelookup.performformlookup();

i don't have adequate form set test lookup, may need play around in testing environment, have used similar method in past.
