Halachos for Erev Shabbos Kodesh
1)
If one recited Ya'aleh V'Yavo during the Bracha of Shomea Tefilah or
within another of the middle set of brachos in Shemona Esrei, and not in
its rightful place in the Bracha of Avodah (Retzei) he has not
satisfied his obligation. (Sefer Chayei Moshe Siman 422:1)
2)
If instead of inserting the proper words "Yom Rosh HaChodesh Hazeh" in
Ya'aleh V'yavo, the words "Chag Hasukkos Hazeh" or "Chag Hamatzos Hazeh"
or the name of another Yom Tov was recited, he has not satisfied his
obligation and must repeat it correctly. (Chayei Moshe ibid.)
However,
if instead of "Yom Rosh HaChodesh Hazeh" he said "Yom Hazikaron Hazeh",
the words inserted on Rosh Hashana, according to some Poskim he may
have satisfied his obligation. (See Shu"t Hisorerus Teshuva
Vol. 1 Siman 193 based on Talmud Eruvin 40a that teaches that the words
"Yom Hazikaron" cover both Rosh Hashana and Rosh Chodesh; see also
Machzor Vitri 321)
Halachos for Shabbos Kodesh
1)
A woman that forgets Ya'aleh V'Yavo in her Shemona Esrei, according to
some Poskim isn't required to repeat the Shemona Esrei. (Chayei Moshe Siman 422:1)
Other
Poskim, however, maintain that she too must repeat the Shemona Esrei,
especially if she is someone that usually davens on a steady basis. (ibid.)
2)
When the Shliach Tzibbur repeats Shemona Esrei and recites Ya'aleh
V'Yavo, the custom is for the congregation to answer Amen after he says
"Zachreinu Hashem Elokeinu Bo L'Tovah", after "U'fakdeinu Vo L'Vracha"
and after "V'Hoshi'einu Vo L'Chaim [Tovim]" (See Drisha on the Tur Siman 127
