Creating an indicator variable

Hello everybody,

I have data as shown in the table below, wherein I need to create an indicator based on combined delivery of AC models.

Have table:

#.	Year	id	AC model	component	date	time1	time2
1	1989	aaa	001	bb1	ccc	abc	xyz
2	1989	aaa	002	bb1	ccc	abc	xyz
3	1989	aaa	001	bb1	ccc	efg	hij
4	1989	aaa	002	bb1	ccc	efg	hij
5	1989	aaa	001	bb1	ooo	fdc	hkg
6	1989	aaa	002	bb1	ooo	fdc	hkg
7	1989	aaa	001	bb2	ddd	lmn	opq
8	1989	aaa	002	bb2	eee	def	ghi
9	1989	aaa	003	bb1	fff	rst	uvw
10	1989	aaa	004	bb1	fff	rst	uvw
11	1990	bbb	001	bb1	ggg	def	ghi
12	1190	bbb	002	bb1	ggg	def	ghi
13	1990	bbb	001	bb2	hhh	jkl	mno
14	1990	bbb	001	bb2	iii	jkl	mno
15	1990	bbb	002	bb2	kkk	fgh	ijk
16	1990	bbb	002	bb2	kkk	fgh	ijk
17	1990	aaa	003	bb1	jjj	vwx	cde
18	1990	aaa	004	bb1	jjj	vwx	cde
19	1991	ccc	001	bb1	lll	bcd	mno
20	1991	ccc	002	bb1	mmm	qew	pqr
21	1991	ccc	005	bb1	sdj	djg	jfk
22	1991	ccc	006	bb1	sdj	djg	jfk

So basically, wherever an AC model with the same id and component = bb1 has been delivered on the same date and in the same time frame, there needs to be an indicator for a combined delivery. For AC model = 001 and 002, indicator = "A" (rows 1&2, 3&4, 5&6 and 11&12) For AC model = 003 and 004, indicator = "B" (rows 9&10 and 17&18). For AC model = 005 and 006, indicator = "C" (rows 21&22) and so on and so forth.

If an AC model with the same id and component = bb1 has different delivery dates/times, then the delivery is not combined and indicator = AC model (rows 19&20). Similarly, in cases where component = bb2, indicator = AC model (rows 7, 8, 13, 14, 15 & 16).

The delivery can be at different times on the same date (as seen in rows 1&2 and 3&4) or on different dates/times (rows 5&6). Also, the delivery combination is never random and always as pairs of 001 and 002, 003 and 004, 005 and 006, etc.

The row # and year are only for reference and not to be taken into consideration for the indicator. The table should look as below:

Want table:

#.	Year	id	AC model	component	date	time1	time2	Indicator
1	1989	aaa	001	bb1	ccc	abc	xyz	A
2	1989	aaa	002	bb1	ccc	abc	xyz	A
3	1989	aaa	001	bb1	ccc	efg	hij	A
4	1989	aaa	002	bb1	ccc	efg	hij	A
5	1989	aaa	001	bb1	ooo	fdc	hkg	A
6	1989	aaa	002	bb1	ooo	fdc	hkg	A
7	1989	aaa	001	bb2	ddd	lmn	opq	001
8	1989	aaa	002	bb2	eee	def	ghi	002
9	1989	aaa	003	bb1	fff	rst	uvw	B
10	1989	aaa	004	bb1	fff	rst	uvw	B
11	1990	bbb	001	bb1	ggg	def	ghi	A
12	1190	bbb	002	bb1	ggg	def	ghi	A
13	1990	bbb	001	bb2	hhh	jkl	mno	001
14	1990	bbb	001	bb2	iii	jkl	mno	001
15	1990	bbb	002	bb2	kkk	fgh	ijk	002
16	1990	bbb	002	bb2	kkk	fgh	ijk	002
17	1990	aaa	003	bb1	jjj	vwx	cde	B
18	1990	aaa	004	bb1	jjj	vwx	cde	B
19	1991	ccc	001	bb1	lll	bcd	mno	001
20	1991	ccc	002	bb1	mmm	qew	pqr	002
21	1991	ccc	005	bb1	sdj	djg	jfk	C
22	1991	ccc	006	bb1	sdj	djg	jfk	C

I can do some very basic programming in SAS but this is completely beyond the scope of my experience/expertise. Would really appreciate all help. Thanks in advance.
